MaxTester 600 Series
A guide to performing a closed circuit resistance test for verification of the Copper Test leads. This is a useful validation for when the Copper measurements are not as expected.
Procedure to follow
1. Connect all three test leads (A, B and Earth) together to form a closed electrical circuit.
2. On your EXFO MAX Tester, press the Home button on the keypad and select Copper Test.
3. Select Multimeter.
4. Select Resistance.
A closed circuit should give 0 Ohms (or close to) across all three pairs (as shown in the picture below).
If you observe high resistance on one or more pair then this could indicate a problem with the test leads or crocodile clips. Try with a new set of test leads and clips by following the procedure MaxTester 600 series - Compensating the Copper test leads
