IV.Fault inspection and processing of China Factory Wholesale Price DC Resistance Test Equipment
  Phenomenon Reason Solution
1 Green light don't turn on when
 power switch connected
Current lines open a 
circuitPower fuse fusing
Change power lines
Change power fuse
2 Red light don't turn on when
push the red button
Pressure regulating
didn't return to 0
Potentiometer return to 0
3 Red light turns on when push 
the red button, while raise voltage,
red light turns off, red light turns on
High voltage output 
terminal tester 
has short circuit
Check the output electric
cable.Check the tested 
4 During raise voltage, red light 
turns off, green light turns on.
Tester discharge or 
break-down over voltage
 or over current protection
Check the tested 
products reset setting
