6．3 Preparation for measurement

Before testing, always check the following:-

1. The low battery Indication " " is not displayed

2. There is no visually obvious damage to the tester or to the test leads.

3. Test the continuity of the test leads by switching to continuity test and

shorting out the lead ends. A high reading will indicate that there is a faulty

lead or that the fuse is blown.

4. MAKE SURE THAT THE CIRCUIT TO BE TESTED IS NOT LIVE. A

warning LED is lit if the instrument is connected to a live circuit but test the

circuit as well!

6．4 Insulation resistance measurement

KEW 6010B has a selectable, double test voltage of 500V and 1000V DC.

1. Select the insulation resistance setting by rotating the function switch to the

required test voltage - "500V" or "1000V" as indicated under the "insulation"

test section of the functional switch, after making sure that the instrument is

not connected to a live circuit.

2. Attach the test leads to the instrument and to the circuit or the appliance

under test. (see Figs 7 & 8)

Note : Insulation testing must only be undertaken on de-energised circuits.
