Fast Photo-Electric Tester

The Fast Photo-Electric Brightness Test Meter consists of three main parts: electrical parameter measurement circuit, photometric parameter measurement circuit and CPU system circuit. The voltage and current signals are amplified and sent to the high-speed A/D converter, and then the converted digital signal is sent to the microprocessor, the input current signal of the brightness detector is sent to the A/D converter through I/V conversion, and then the digital conversion signal is sent to the microprocessor. The microprocessor processes the input photometric parameter and electrical parameter data, which can automatically switch between different ranges and calculate and display the data at the same time.

Feature:
• Four windows display electrical parameters and photometric parameters, reducing the possibility of incorrect reading
• The tester comes with built-in lamp holders, and the lamp can be directly installed for testing
• The measured electrical parameters are true RMS values
• Photodetector V(λ) correction accuracy is high, meeting national CLASS 1 brightness meter requirements
• The measurement range can be automatically switched according to the test results
• Built-in dual watchdog, high reliability, no crash in complex environment
