5.1 Horizontal Commissioning of the Main Unit

5.1.1 Single-Character Laser Ready

Insert the batteries into the laser pointer and turn it on.

Gambar 31

Gambar 31.1

Install the single-line laser onto the Goniophotomoeter and secure it in place.

Gambar 31.2

Buka perangkat lunak.

Jumlah	Note

③	Kemudian klik untuk membuka antarmuka kontrol sudut.

Gambar 31.3

Jumlah	Note
①	Masukkan 0
②	Click to rotate the Gamma axis to the 0-degree position
③	Click, and the single-character laser begins to rotate on its own.

Gambar 31.4

Secure a sheet of white paper at the far end of the darkroom. Use a pen to trace the path of the red laser dot, creating a circular pattern of varying sizes, as shown by the black circular path in the figure below.

Gambar 31.5

Click the “Stop” button on the “Angle Control” interface to stop the straight-line laser from rotating. Then, depending on the actual situation, adjust the four small Allen screws shown in the figure below to align the straight-line laser spot exactly at the center of the circular path, as indicated by the red arrow in the figure above.

Gambar 31.6

Then restart the straight-line laser’s rotation, redraw the trajectory, and repeat the above steps until the trajectory of the straight-line laser dot forms a point (or the trajectory radius is small enough), rather than a circle. Then click the “Stop” button on the “Angle Control” interface to stop the straight-line laser from rotating. Once debugging is complete, all four small Allen screws on the single-line laser should be fully tightened.

Note: Once the single-line laser has been properly calibrated, it must remain attached to the Goniophotomoeter until the installation and calibration are complete before being removed.

5.1.2 Crosshair Laser Ready

Find the crosshair laser device and tripod.

Gambar 32

Lepaskan laser garis silang dan baterai. Masukkan baterai ke dalam laser garis silang. Sakelar daya terletak di sisi perangkat. Putar sakelar ke posisi "buka kunci" untuk menghidupkan perangkat.

Jumlah	Note
①	Power switch: Turn it to the “Unlock” position to turn on the power.
②	VH refers to vertical and horizontal laser switches, respectively.

Gambar 33

Mount the crosshair laser onto the tripod.

Catatan: Laser garis silang ini memiliki fitur perataan otomatis. Jika tidak rata, alarm akan berbunyi. Hal ini mungkin disebabkan oleh permukaan yang tidak rata atau tripod yang tidak terpasang dengan benar. Pastikan laser garis silang tetap rata setiap saat selama penggunaan.

5.1.2 Steps for Horizontal Commissioning of the Host Machine

According to the darkroom drawings, the center height of the LSG-1800A goniophotomoeter is 1375 mm. Using a tripod, adjust the height of the horizontal laser beam from the crosshair laser to 1375 mm. At this height, the horizontal laser beam should pass through the center of all light-transmitting holes in the darkroom partition.

Gambar 34

Please note: Do not place any objects on the Goniophotomoeter or within its rotation range to prevent damage to the equipment during rotation.

Click the continuous rotation button in any direction, and the Gamma axis of the Goniophotomoeter will begin to rotate continuously.

Gambar 36

At this point, observe the horizontal laser beams emitted by the single-line and cross-line lasers from the main axis of the Goniophotomoeter.

Gambar 37

Then, using an appropriate wrench, raise the goniophotomoeter and level it by adjusting the height of its four support legs. The final result of the calibration: regardless of the Gamma angle of the goniophotomoeter, its straight laser beam is perfectly aligned with the horizontal laser beam, as shown in the figure below.

Gambar 38

You’ll need plenty of patience to complete this step. Once the adjustment is complete, make sure all four legs of the main unit are firmly on the ground. Then click the “Stop” button on the software’s angle control interface to stop the Goniophotomoeter from rotating. Next, secure the four legs of the Goniophotomoeter by tightening the screws at the top of each leg. Once the position and level of the Goniophotomoeter main unit have been properly adjusted, do not move it again, as doing so will cause the test results to be inaccurate.

5.2 Kalibrasi Probe Fotometri

5.2.1 Calibration of the Photometric Probe at the 0-Degree Position

Jumlah	Note
①	Masukkan 0
②	Click any rotation direction to rotate the Gamma axis back to the 0-degree position.

Gambar 39

Verify that the single-line laser beam is passing through the exact horizontal center of the last partition at this point.

Gambar 40

If not, follow the steps below.

Jumlah	Note
①	Please enter a small angle value here based on the actual situation, such as 1, 0.1, 0.05, etc.
②	Select a rotation direction, and rotate the Gamma axis until the straight laser beam passes through the exact center of the horizontal plane of the last partition.
③	Click “Set to 0 Degrees” to set the current position of the Gamma axis on the near-field luminance probe to 0 degrees. The password is LISUNGROUP.

Gambar 40.1

Note 1: After setting the Gamma axis of the near-field photometer to 0 degrees, do not arbitrarily set it to 0 degrees again, as this will cause deviations in the test results.

Note 2: Definition of the Gamma angle for a goniophotomoeter. The direction directly facing the photometer probe is defined as 0 degrees/360 degrees. When rotated clockwise, the angle value increases from 0 degrees to 360 degrees; when rotated counterclockwise, the angle value decreases from 360 degrees to 0 degrees. Since angle notation may vary, -90 degrees and 270 degrees correspond to the same position.

5.2.2 Mounting the Photometric Probe

Rotate the light sensor’s lens hood counterclockwise and remove it.

Gambar 41

Kotak kemasan lampu standar berisi cermin kecil.

Gambar 42

Gambar 43

Lepaskan reflektor kecil dan pasang ke probe.

Gambar 44

At this point, the Gamma axis of the near-field photometer probe is still at the 0-degree position. Slightly move the probe base and adjust the screws at points ① and ② to adjust the probe’s height and orientation. Position the probe so that the straight laser beam coming from the main axis hits the exact center of the mirror, and ensure that the reflected beam returns along the same path.

Gambar 45

Kemudian, kencangkan alas braket probe ke lantai dengan sekrup.

Gambar 46

Once secured, you may need to make minor adjustments to the probe’s height and orientation so that the straight laser beam continues to hit the exact center of the reflector and the reflected beam returns along the same path. After calibration is complete, ensure that all screws are tightened. Then remove the reflector and reinstall the light probe’s light shield.

Note: Once the probe’s position and orientation have been set, do not change them, as doing so may cause the test data to be inaccurate.

Anda dapat mengamankan adaptor daya probe fotometer ke braket probe seperti yang ditunjukkan pada gambar di bawah untuk melindungi jack daya probe.

Gambar 47

5.3 Cross-Line Laser Installation

Finally, the crosshair laser must be mounted on the side wall of the darkroom. Depending on the specific layout of each darkroom, the crosshair laser can be mounted on either the left or right wall. Take the darkroom layout shown in the figure below as an example.

Gambar 52

Go to the angle control screen.

Jumlah	Note
①	Enter 90 (if the installation position of the cross-hair laser in your darkroom blueprint is different, enter -90)
②	Click to rotate the Gamma axis to a 90-degree position, so that the main-axis laser beam is directly aligned with the position where the crosshair laser is installed.

Gambar 53

Secure the crosshair laser to the triangular mount we provide.

Gambar 54

Turn on the cross-hair laser and use the direction of the single-line laser to roughly determine the position of the cross-hair laser.

Gambar 55

Fine-Tune the Position of the Crosshair Laser: The centerline of the straight laser should be perfectly aligned with the centerline of the crosshair laser. You can verify and adjust the position using the following method. Place a sheet of white paper at the exit of the crosshair laser and at the exit of the single-line laser. If the centerline of the single-line laser aligns with the centerline of the crosshair laser at both locations, you can confirm that the position and orientation of the crosshair laser are correct.

Gambar 56

Gambar 57

Next, secure the cross-laser tripod to the wall with screws. Once secured, you can still loosen the screws if necessary to make slight adjustments to the cross-laser’s position horizontally and vertically, ensuring it remains correctly aligned. After calibration, all screws should be tightened securely.

Gambar 58

Then rotate the gamma axis back to the 0-degree position. The cross-shaped laser beam is projected onto the opposite wall. This creates a permanent mark. In other words, when the cross-shaped laser beam is projected in this direction, it indicates the horizontal and vertical center positions of the Goniophotomoeter. This mark is needed for both calibration and testing.

Gambar 59

Installation and commissioning are complete. Remove the flat-head laser from the main shaft of the Goniophotomoeter and store it safely.

5.5 Membersihkan

You may shut down all equipment. When doing so, first turn off the power switch on each device, and then turn off the main power switch for the cabinet. Next, clean the darkroom and control room thoroughly. To prevent dust from entering the equipment, cover the devices with dust-proof cloths before cleaning. After cleaning, turn all equipment back on and continue with the calibration and testing procedures.

Catatan: Jaga agar ruang gelap sebisa mungkin bebas debu selama penggunaan.

Gambar 64

Lampu standar harus disesuaikan sehingga berkas laser berbentuk salib diarahkan ke tengah cermin kecil, dan berkas laser horizontal dan vertikal yang dipantulkan dari cermin bertepatan persis dengan berkas laser berbentuk salib aslinya.

Gambar 65

Based on our experience, follow these steps for calibration: First, adjust the height of the standard lamp to the appropriate position. The vertical reflected laser can be calibrated by rotating the calibration target, while the horizontal reflected laser can be calibrated by adjusting the pitch of the standard lamp. After calibration, the center height of the standard lamp may change, requiring you to readjust its height. Continue the reflection adjustment until the cross-shaped laser beam is projected onto the center of the small mirror, and the reflected horizontal and vertical laser beams perfectly align with the original cross-shaped laser beam.

Once the standard lamp is properly aligned, carefully remove the small reflector, taking care not to alter the alignment of the standard lamp while doing so. Then turn off the cross-hair laser.

Gambar 69

Note: The test distance is the distance from the center of the Goniophotomoeter to the surface of the photometric probe. The distance calculated by the software should be close to the actual distance; an error of 1% or less is considered normal. If the error is too large, please refer to Section 2.3.1 to verify that the darkroom is functioning properly, and refer to Chapter 5 to review the calibration steps.

After calibration is complete, you can turn off the standard lamp using the software. Since the standard lamp becomes quite hot during use, wait for it to cool down before placing it back in its packaging for safe storage. Remove the calibration rod and store it properly.

6.4 Kalibrasi dan Pemeliharaan

Jumlah	Note
①	Lighting fixture types—indoor lights, outdoor lights, or plant grow lights—these three types of lighting fixtures are subject to C-Gamma testing.
②	Select whether the light fixture is symmetrical. Unless there are specific requirements, select the first option, “asymmetrical,” regardless of whether the light fixture being tested is symmetrical or not (to obtain the actual data for the light fixture).
③	C-plane angle range: Select 0 to 180 degrees; no modification is needed. For data ranging from 180 to 360 degrees, the software will automatically convert it to C-plane angle intervals. For symmetrical luminaires, such as indoor lights, you can select a larger interval, such as 30 degrees; for asymmetrical luminaires, such as streetlights, you can select a smaller interval, such as 10 degrees. The smaller the angle interval, the higher the test accuracy, but the longer the testing time. If time permits, it is recommended to select a smaller angle interval.
④	Gamma plane angle range: If the sample’s light irradiation angle exceeds 180 degrees (e.g., incandescent bulbs), select -180 degrees to 180 degrees; if the sample’s light irradiation angle is less than 180 degrees (e.g., panel lights), you can select an angle interval for the Gamma plane ranging from -90 degrees to 90 degrees. Unless there are special requirements, selecting 1 degree is sufficient. The specific angle interval selected here has no effect on test speed.
⑤	If the system has multiple photometric probes, please select the one you want to use.
⑥	Fixed Range: If you are consistently measuring the same type of light fixture and the luminous intensity data does not vary significantly, you can check this box to save time. However, if you have ample time or frequently test light fixtures with different luminous intensities, we recommend leaving this box unchecked so that the photometer can automatically select the appropriate range for each light fixture.
⑦	To set the monitoring angle during lamp warm-up, simply set it to (0, 0).
⑧	Normalization refers to the decision of whether to apply a uniform value to the first row of data in the luminous intensity table of a test report; certain standards, such as the U. S. streetlight standard, may require you to perform a similar adjustment. There are three options: no normalization, normalization to the maximum value (which slightly increases the luminaire’s total luminous flux), and normalization to the average value (which leaves the luminous flux essentially unchanged).
⑨	If you need to remove all stray light outside a specific angle, check this option and then enter the desired angle . For example: If you check this option and enter 60, the data outside ±60 degrees of the luminaire’s gamma plane will automatically be set to 0.
⑩	Enter the number of light sources in the luminaire and the rated luminous flux of each light source. If you do not know this information, you may leave it blank; it will not affect the test results.
⑪	Masukkan dimensi permukaan pemancar cahaya sampel. Untuk perlengkapan pencahayaan dalam ruangan, perangkat lunak memerlukan data ini untuk menghitung kurva batas luminansi, UGR, dan parameter lainnya.
1	Enter information about the sample luminaire
⑬	Enter the temperature and humidity of the test environment (i.e., the darkroom)
⑭	Click OK to proceed to the warm-up screen, or to the test screen.

Solusi: Instal ulang driver, sambungkan kabel komunikasi sesuai dengan pengenal perangkat, mulai ulang perangkat lunak, dan coba lagi.

12.2 Kesalahan Pengujian

12.2.1 Anomali Fluks Cahaya

Cause of the malfunction: Check whether the light source is stable and whether the warm-up time is sufficient; verify that the equipment is properly calibrated, that the test distance is correct, and that the reference lamp is functioning properly; check whether there is any external light interference in the darkroom and whether the light path is obstructed.

Solution: Extend the warm-up time, recalibrate the instrument, turn off other light sources in the darkroom, and remove any obstructions from the optical path.

12.2.2 Anomali UGR

Cause of error: Dimensions of the luminaire’s light-emitting surface were not entered; the luminaire’s beam angle is less than 45°; the calculation standard was selected incorrectly.

Solusi: Masukkan dimensi permukaan pemancar cahaya luminer (panjang/lebar/tinggi) dengan benar; verifikasi bahwa luminer tersebut adalah luminer dalam ruangan (sudut pancaran harus memadai); pilih standar CIE 190:2010 dan hitung ulang.

12.3 Goniophotometer Tidak Berputar

Cause of the malfunction: Check whether the main unit is powered on and whether the wiring is correct; check whether the angle controller inside the cabinet is operating normally; confirm whether any foreign objects are jammed in the rotating shaft.

Solusi: Periksa catu daya dan kabel, dan singkirkan benda asing apa pun; mulai ulang perangkat dan perangkat lunak, lalu coba lagi.

12.4 Kegagalan Perangkat Lunak

12.4.1 Kerusakan Perangkat Lunak

Penyebab masalah: Periksa apakah Anda masuk ke sistem operasi komputer dengan akun administrator; verifikasi bahwa perangkat lunak telah terinstal sepenuhnya; periksa apakah file basis data rusak.

Solution: Create a new database file and save it; restore the default way to open LGF files.

12.5 Kegagalan Daya

12.5.1 DC Power Output Abnormalities

Penyebab kerusakan: Sakelar AC/DC pada kabinet tidak disetel ke DC; tegangan atau arus sampel melebihi batas catu daya DC; korsleting pada sampel;

Penyelesaian Masalah: Harap verifikasi bahwa tegangan dan arus sampel berada dalam rentang keluaran catu daya DC. Misalnya, DC3005 Model ini memiliki tegangan keluaran maksimum 30 V dan arus keluaran maksimum 5 A. Periksa apakah sampel mengalami korsleting; jika ya, perbaiki sampel sebelum melakukan pengujian ulang.

12.5.2 Tidak Ada Output AC

Cause of the malfunction: The cabinet’s AC/DC switch was not set to the AC side, and the overload protection was triggered;

Troubleshooting Steps: Check the AC power output wiring and sample connections to ensure there are no loose connections or short circuits. If the overload protection is triggered, turn off the power, let the unit cool for 5 minutes, and then restart it. Ensure that the sample’s power consumption remains within the AC power output range; for example, the LSP-500VARC memiliki daya keluaran maksimum 500 W.
