5. Calibration of darkroom equipment (Each step must be performed carefully and thoroughly; otherwise, calibration data may be inaccurate and test results may be abnormal.)

5.1 Horizontal Commissioning of the Main Unit

5.1.1 Laser Ready

There is a laser switch on the back of the goniophotomoeter’s main arm. When you turn on the line laser switch, you will see a red line laser beam emitted directly in front of the main arm.

Gambar 31

Find the crosshair laser device and tripod.

Gambar 32

Remove the cross-line laser and the batteries. Insert the batteries into the cross-line laser. The power switch is located on the side of the device. The device turns on when the switch is set to the “unlocked” position.

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.

Note: The cross-line laser is self-leveling. If the cross-line laser is not self-leveled, an audible alarm will sound. This may be due to an uneven surface or a tripod that is not properly set up. Please ensure that the cross-line laser remains self-leveled at all times during use.

5.1.2 Steps for Horizontal Commissioning of the Host Machine

According to the darkroom drawings, the center height of the LSG-1890B goniophotomoeter is 1510 mm. Using a tripod, adjust the height of the horizontal laser beam from the crosshair laser to 1510 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.

Buka perangkat lunak.

Jumlah	Note
①	Click to switch angle modes
②	Click ① to display the C-Gamma angle here instead of the B-Beta angle.
③	Kemudian klik untuk membuka antarmuka kontrol sudut.

Gambar 35

Click the continuous rotation button for any direction. The Gamma axis of the Goniophotomoeter will then 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 legs. The final result of the calibration: Regardless of the Gamma angle of the goniophotomoeter, its straight laser beam perfectly aligns with the horizontal laser beam, as shown in the figure below.

Gambar 38

You’ll need plenty of patience to complete this step. Once adjusted, 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, lock the four legs of the Goniophotomoeter in place using the screws at the top. Once the position and level of the Goniophotomoeter main unit have been properly adjusted, do not move it again, as this will cause deviations in the test results.

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 single-line laser passes through the exact center of the last partition horizontally.
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 rotating clockwise, the angle value increases from 0 degrees to 360 degrees; when rotating 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 cover counterclockwise and remove it.

Gambar 41

Kotak kemasan lampu standar berisi cermin kecil.

Gambar 42

Gambar 43

Remove the small reflector and attach it to the probe.

Gambar 44

At this point, the Gamma axis of the near-field photometer 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 travels back along the same path.

Gambar 45

Kemudian, kencangkan alas braket probe ke lantai dengan sekrup.

Gambar 46

Once secured, you may need to make slight 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 adjust them, as doing so may cause the test data to be inaccurate.

You can secure the photometer probe’s power adapter to the probe mount as shown in the figure below to protect the probe’s power jack.

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 crosshair 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 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 crosshair laser and use the direction of the single-line laser to roughly determine the position of the crosshair 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 cross-shaped laser and at the exit of the single-line laser. If the centerline of the single-line laser aligns with the centerline of the cross-shaped laser at both locations, you can confirm that the position and orientation of the cross-shaped laser are correct.

Gambar 56

Gambar 57

Next, secure the cross-laser tripod to the wall using screws. Once secured, you can still loosen the screws if necessary to make slight adjustments to the cross-laser in both the horizontal and vertical directions, ensuring it remains properly aligned. After calibration is complete, 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. You can use this to create a permanent mark. That is, 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. Turn off the line laser on the main shaft of the Goniophotomoeter.

5.4 Membersihkan

You may shut down all equipment. When doing so, first turn off the power switch on each individual device, and then turn off the main power switch for the cabinet. Next, thoroughly clean the darkroom and control room. 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 during removal. Then turn off the cross-line laser.

6.2 Kalibrasi Probe Fotometri

Jumlah	Note
①	Jenis perlengkapan pencahayaan: lampu dalam ruangan, lampu luar ruangan, atau lampu pertumbuhan tanaman—ketiga jenis perlengkapan pencahayaan ini tunduk pada pengujian C-Gamma.
②	Select whether the luminaire is symmetrical or asymmetrical. Unless there are specific requirements, select the first option (asymmetrical) regardless of whether the luminaire being tested is symmetrical or not (to obtain the luminaire’s actual data).
③	Rentang sudut bidang C: Pilih 0 hingga 180 derajat; tidak perlu modifikasi. Untuk data yang berkisar dari 180 hingga 360 derajat, perangkat lunak akan secara otomatis mengonversinya. C-plane angle intervals. Symmetrical luminaires, such as indoor lights, can use a larger interval (e.g., 30 degrees), while asymmetrical luminaires, such as streetlights, can use a smaller interval (e.g., 10 degrees). The smaller the angle interval, the higher the test accuracy, but the longer the test will take. If time permits, we recommend selecting 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 may select a Gamma plane angle interval ranging from -90 degrees to 90 degrees. Unless there are special requirements, a 1-degree interval 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	For standard luminaires undergoing standard testing, select “Normal Speed”; if the luminaire being tested has an extremely narrow beam angle, select “Slow Speed” to obtain more accurate test results; for expedited testing, select “Fast Speed.”
⑦	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. If you have ample time, or if you frequently test lamps with different luminous intensities, we recommend leaving this box unchecked; in this case, the photometric probe will automatically select the appropriate range for each lamp and enter continuous scanning mode. This is suitable when the angular interval of the Gamma plane is between -180 degrees and 180 degrees. During the test, when the Gamma angle approaches ±180 degrees, simultaneously rotating the C-axis to the next scanning position—that is, the Gamma axis rotates continuously without stopping to save time. If you have ample time, we recommend leaving this option unchecked.
⑧	To set the monitoring angle during lamp warm-up, simply set it to (0, 0).
⑨	Normalisasi mengacu pada keputusan apakah akan menerapkan nilai seragam pada baris pertama data dalam tabel intensitas cahaya pada laporan pengujian; standar tertentu, seperti standar lampu jalan AS, mungkin mengharuskan Anda untuk melakukan penyesuaian serupa. Ada tiga pilihan: tanpa normalisasi, normalisasi ke nilai maksimum (yang akan sedikit meningkatkan fluks cahaya total luminer), dan normalisasi ke nilai rata-rata (yang pada dasarnya tidak mengubah fluks cahaya).
⑩	If you need to remove all stray light outside a specific angle, check this box and 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.
⑪	Enter the number of light sources in the luminaire and the rated luminous flux of each light source. If you do not know these values, you may leave them blank; this will not affect the test results.
1	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.
⑬	Enter information about the sample light fixture
⑭	Enter the temperature and humidity of the test environment (i.e., the darkroom)
3	Klik OK untuk menuju layar pemanasan, atau menuju layar pengujian.
