Multifunction Tester
3. Use the F1 to select the test voltage. Most insulation testing is performed at 500 V, but observe local test
requirements.
4. Press and hold TEST button until the reading settles and the
tester beeps.
Note
Testing is inhibited if voltage is detected in the line.
The primary (upper) display shows the insulation resistance.
The secondary (lower) display shows the actual test voltage.
Note
For normal insulation with high resistance, theactual test voltage (UN) should always be equal to or higher
than the programmed voltage. If insulation resistance is bad, the test voltage is automatically reduced to limit
the test current to safe ranges.

6.3 Using the RE Function

6.4 Earth Resistance Display/Switch and Terminal Settings

The earth resistance test is a 3-wire test consisting of two test stakes and the earth electrode under test.
This test requires an accessory stake kit. Connect as shown in right figure .
Best accuracy is achieved with the middle stake at 62 % of the distance to the far stake. The stakes should
be in a straight line and wires separated to avoid mutual coupling.
The earth electrode under test should be disconnected from the electrical system when conducting the test.
Earth resistance testing should not be performed on a live system.

6.5 To measure earth resistance

1. Turn the rotary switch to the RE position.
2. Press and release TEST button. Wait for the test to complete.
The primary (upper) display shows the earth resistance reading.
The Test Current will be displayed in the secondary display.
If  V oltage detected between the test rods greater than 10 V, the test is inhibited.
