➡️Method of use

✅Starting up
(1) Connect the tester power cord with AC220V outlet, start main power, after IPC start the Windows 7 system, the tester auto enter software main interface.
(2) Turn on the power amplifier, connect the current, voltage circuit, connect switch input if necessary, and choose the appropriate software module to test.
Note:
① When connecting the current loop, sparking phenomenon may occur, this is normal. There is 20V DC voltage on the current loop. To avoid the spark phenomenon, please turn off the power switch of the power amplifier, then connect the wire of the current loop, and then turn on the power switch of the power amplifier after connecting, there will be no spark phenomenon.
② Check the wiring is correct. If the current open circuit indicator lights on, it means the corresponding current loop wrong wiring. If the voltage short circuit indicator lights on, it means the corresponding voltage loop wrong wiring. The voltage short circuit indicator cannot return to normal condition itself. After the voltage circuit failure settled, turn off the power amplifier for 20 seconds, then re-start it, there will not be red indicator on voltage loop, It means the wiring is OK.
✅Turn off
(1) Turn off the power amplifier switch first.
(2) Close the test software menu. At the “start” column press “shutdown”, when the Window system indicates “safe to shutdown”, turn off the main power, disconnect the test wires, and put the tester into the case.
