4.1 Turning On The Constant Temperature Integrating Sphere

Refer to Section 3.1, connect the Constant Temperature Integrating Sphere to a suitable power source, and turn it on.

4.2 Mounting and Connecting the Stage

4.2.1 Persiapan

To facilitate transport, the stage and strip light fixture are secured inside the Integrating Sphere. Remove the panel marked in Figure 6 to reveal the stage and strip light fixture secured inside.

After installing the stage and connecting its cables as described in Section 4.2, and after aligning the crosshairs as described in Section 4.4.1, reinstall this panel.

4.2.2 Mount Installation

The stage can be mounted either on top of the Integrating Sphere or at the bottom. Here, we use the example of mounting the stage at the bottom, as shown in Figure 7.

Feed the four-core cable for the stage through the bottom cable opening, as shown in Figure 8.

Then tighten the mounting screws to secure the stage.

4.2.3 Four-Conductor Cable Connection to the Stage

As shown in Figure 9, simply connect the four-conductor cable from the stage to the four-conductor wires provided inside the junction box, matching them one-to-one by color.

Both the junction box (Fig. 10) and the stage (Fig. 11) are equipped with red and black POWER and SENSE terminals. The terminals on both ends correspond one-to-one; simply connect them according to the cable colors.

4.3 Installation of Linear Light Fixtures

When you need to test linear lights, such as LED tubes, you can use a linear light fixture to secure the tube, as shown in Figure 12.

Note: When the strip light fixture is not in use, remove it and store it properly.

4.4 Cross-Line Laser

4.4.1 Crosshair Laser Calibration

Refer to Section 3.1 to turn on the cross-hair laser.

The direction of the cross-laser beam may shift or become misaligned during shipping. Please use a tape measure to confirm the center position of the Integrating Sphere, and then follow the instructions in Figure 13.

Once the crosshair laser is properly adjusted, you can reinstall the panel you removed.

4.4.2 Uses of Cross-Line Lasers

The crosshair laser is used to assist with light installation. Turn on the crosshair laser during installation to ensure that the light-emitting surface of the installed light is positioned exactly at the center of the Integrating Sphere. Turn off the crosshair laser during testing.

5. Hardware Operation of The Constant Temperature Integrating Sphere

5.1 Connecting Spectrometer Accessories

Refer to Section 3.1 to connect the spectrometer’s accessories—such as Optical Fibers, photometric probes, and temperature probes—to the corresponding dedicated ports on the Integrating Sphere.

5.2 Installation and Connection of Sample Luminaires

5.2.1 Bulb Lamps and Strip Lights

For incandescent bulbs, the mount includes an E27 socket. Incandescent bulbs can be installed directly into the E27 socket or connected to it using an adapter; no additional wiring is required inside the Integrating Sphere.

For strip lights, refer to Section 4.3 and use strip light fixtures.

5.2.2 Other Lighting Fixtures

For other types of lights, simply place them on the mounting platform and secure them using the M6 screw holes provided on the platform to prevent them from slipping off.

5.2.3 Confirmation of the Light-Emitting Surface Installation Location

The stage is height-adjustable. Please refer to Section 4.4.2 and use the cross-hair laser to verify that the sample’s emitting surface is positioned exactly at the center of the Integrating Sphere. After adjusting the height, make sure the screws are securely tightened to prevent the stage from suddenly falling; see Figure 14.

5.2.4 Connecting the Sample Power Cord

Simply connect the sample power cord to the two terminals labeled “POWER” on the stage. The two red terminals and two black terminals labeled “POWER” and “SENSE” on the stage are already internally short-circuited, so there is no need to connect the wires to the “SENSE” terminals on the stage separately.

5.3 Connecting the External Power Cable and Sampling Cable

The four terminals on the front of the Constant Temperature Integrating Sphere’s junction box are used to connect to your other devices. The two “POWER” terminals connect to the sample power supply, and the two “SENSE” terminals connect to the voltage sensing leads.

5.4 Using the Auxiliary Lamp Fixture

Please install the Auxiliary Lamp into the MR16 lamp holder on the fixture, as shown in Figure 15.

The Auxiliary Lamp clamp comes with two pre-installed power cords. When using the Auxiliary Lamp, connect it using an extension cord to a power source that meets the specified requirements.

6.2 Heating and Cooling Procedures

Constant Temperature Integrating Sphere is primarily used for high-temperature testing. It heats up relatively quickly, typically reaching the set temperature and stabilizing within about 10 to 20 minutes.

The entire interior of the device housing is lined with insulation to prevent heat loss from the interior of the Integrating Sphere. In other words, when the Integrating Sphere is at a high temperature, both chambers inside the device—the chamber containing the Integrating Sphere itself and the chamber between the Integrating Sphere and the outer housing of the device—are at a high temperature.

When you have just completed a high-temperature test and need to allow the internal temperature to cool down to room temperature (25°C), the cooling rate will be relatively slow if you rely solely on the equipment’s temperature control program. If necessary, you can open the Integrating Sphere directly to assist with cooling.

7. End-of-use procedure

7.1 Integrating Sphere Operation

You can allow the unit to cool down naturally using the temperature control program, or turn on the Integrating Sphere to accelerate heat dissipation. Once the temperature inside the sphere has returned to room temperature, if no further testing is required, you may turn off the device’s main power supply.

Once the temperature inside the Integrating Sphere has returned to room temperature, promptly remove the sample and wiring from inside the Integrating Sphere. Do not leave any unrelated accessories inside the Integrating Sphere.

7.2 Close The Integrating Sphere promptly

When the Integrating Sphere is not in use, be sure to keep it closed to prevent dust from entering.

8.2 Items to Be Inspected on a Regular Basis

8.2.1 Structural and Operation Checks

Each month, inspect the opening and closing handles and hinges; if any are loose, tighten the screws. Check that the gap where the two halves meet is even and that no light leaks through.

8.2.2 Inspection of the Inner Wall Coating

Inspect the interior coating monthly to ensure there is no peeling, yellowing, darkening, or staining.

8.3 Guidelines for Long-Term Storage

Storage conditions: Dry, protected from light, dust-free, temperature 0–40°C, relative humidity ≤70% RH; ensure the sphere is completely closed and covered with a dust cover; perform a thorough cleaning and inspection before storage.

8.4 Persyaratan Interval Kalibrasi

To ensure the measurement accuracy and operational reliability of the equipment, it is recommended that it be sent periodically to a qualified third-party metrology laboratory for calibration. The recommended calibration interval is 12 months. Users may determine the specific calibration interval based on usage frequency, environmental conditions, and quality system requirements.
