Product Description

Wide Measuring Range 40A Digital Transformer DC Winding Resistance Meter

I.Introduction

Transformer winding dc resistance tester is essential in transformer handover, overhaul and  change of the lead switch, it's also the important inspection program to after transformer fault.


II.Features

1. Output current is big, test range wide, small volume, light weight, simple operation
2. Test speed fast, high-accuracy, good reiteration test, Strong anti-interference ability
3. With perfect protection circuit, strong reliability.
4. With the functions of discharge acoustics, discharge the instructions clear, reduce errors  operation.

IV.Fault inspection and processing
 

	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 potentiometer  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  products
4	During raise voltage, red light  turns off, green light turns on.	Tester discharge or  break-down over voltage  or over current protection  movement	Check the tested  products reset setting valu
