Q1: The power supply of the instrument is unstable, and it restarts frequently.
A1: The instrument is connected to the computer using a USB cable. The instrument communicates with the computer through the USB cable, and the computer supplies power to the instrument through the USB cable. If the power supply of the computer’s USB port is unstable or insufficient, the instrument will restart frequently.

You can also connect a 5V1A power adapter to the power port on the back of the instrument to ensure that the instrument can be used normally.

Q2: The difference between using the instrument with an integrating sphere and using it with a darkroom.
A2: When connected to an integrating sphere, it is necessary to use a luminous flux standard lamp and calibrate in the form of luminous flux . When connected to a darkroom, it is necessary to use a light intensity standard lamp and calibrate in the form of light intensity (illuminance). And the calibration interface in the figure below ① Select luminous flux or light intensity (illuminance).

LSRF-3 Calibration Interface

In the test setting interface, ① you also need to select luminous flux or light intensity (illuminance) according to the situation. If it is an integrating sphere, select luminous flux, and there is no need to set or modify ② the test distance. If it is a darkroom, select light intensity (illuminance) and need to set the correct ② test distance.

LSRF-3 Test Settings

Note: relevant operations are required for flicker test software and start run up time test software.

Q3: Test results are not stable.
A3: Because the instrument collects data quickly, please warm up the instrument for about 5 minutes before starting calibration or testing. If you do not warm up, the internal components of the instrument may not reach a stable state, and the collected data may be biased.

Q4: After booting up, the screen flickers and cannot run normally.
A4: See Q1 of this FAQ for the same reason.

Q5: A lot of data is not displayed in the test report.
A5: The flicker test needs to be continued for 180 seconds to produce a complete test report, otherwise many data cannot be calculated according to the standard.
