 Troubleshooting Guide 

 

Item  Symptom 

Possible Problem 

Solution 

Reading is incorrect. 

1. Poor connection at the 
Clips. 
2. Broken sensing lead. 

1.Check connection to make sure 
sensing and current teeth are 
touching the device under test 
(DUT). 
2. Inspect sensing cables. 

No Test Current. 
(Current % read zero) 
and resistance 
reading=0 

1. No test current going 
through DUT. 
2. Drive circuit not 
working. 

1. Check Connection to DUT. 
2. Run Calibration Test. 

Have test current but 
resistance reading = 
0. 

1. Broken sense leads. 
2. Reverse sense leads. 

1. Inspect sense leads.
