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.<br \/>\n<strong><br \/>\nFitur:<\/strong><br \/>\n\u2022 Four windows display electrical parameters and photometric parameters, reducing the possibility of incorrect reading<br \/>\n\u2022 The tester comes with built-in lamp holders, and the lamp can be directly installed for testing<br \/>\n\u2022 The measured electrical parameters are true RMS values<br \/>\n- <span class=\"HwtZe\" lang=\"en\"><span class=\"jCAhz ChMk0b\"><span class=\"ryNqvb\">Photodetector V(\u03bb) correction accuracy is high, meeting national CLASS 1 brightness meter requirements<\/span><\/span><\/span><br \/>\n\u2022 The measurement range can be automatically switched according to the test results<br \/>\n\u2022 Built-in dual watchdog, high reliability, no crash in complex environment<\/p>\n<p><strong>Spesifikasi:<\/strong><br \/>\n-\u00a0<strong>Electric parameter:<\/strong><br \/>\n1.
