The troubleshooting method is as follows:


Trouble phenomenon:


1. No response after booting, no display on LCD


Troubleshooting:


1) Check for AC power supply;


2) Check the power cable;


3) Check whether the fuse in the fuse base is blown.


2. The resistance value is too large during the test or displayed as over-range


Troubleshooting:


1) Check whether the measured resistance value is too large;


2) Check whether the voltage input line is connected to the inside of the current output line;


3) Check whether the polarity of the test line is reversed;


4) Check whether the voltage output line is connected well, and whether the joint of the DUT is oxidized.
