What to do if my Fluke 620 doesn’t appear to be measuring correctly?
If your Fluke Cable Tester isn’t measuring correctly, it could be due to defective internal circuitry. Try performing a self-test on the test tool. Also, perform the steps under 'Verifying Proper Operation'.
Why does my Fluke 620 display go blank?
Your Fluke Cable Tester display might be blank because the Battery Save feature turned the test tool off. To resolve this, turn the rotary switch to off, wait 5 seconds, and then turn the switch to TEST. Alternatively, the batteries may be too low, in which case, replace them.
