10. If there were data error, can not connect the device or other problems during use , it
can be solved: exit back to the main menu and re-run the program , then all the data are
restored to default values.
Section 2 Procedures of starting up/shutdown
1. Starting up
(1) Connect the tester power cord with 220V outlet, start main power, after IPC start the
Windows XP 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. It will disappear when the loop short circuit. If
power on the amplifier power switch after connects the circuit loop wire, there will not be
sparking 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, wiring
correctly.
2. 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.
