MAKING MEASUREMENTS

Measuring Volts and Frequency

To measure voltage and frequency:
1. Turn the rotary switch to the V position.
2. Use all (red, blue, and green) terminals for this test. You can use test leads or mains cord
when measuring AC voltage.
• The primary (upper) display shows the AC voltage. The tester reads AC voltage to 500
V. Press F1 to toggle the voltage reading between L-PE, L-N, and N-PE.
• The secondary (lower) display shows mains frequency.

Measuring Insulation Resistance

Figure 9. Insulation Resistance Display/Switch and Terminal Settings
WWarning
To avoid electric shock, measurements should only be performed on de-energized circuits.
To measure insulation resistance:
1. Turn the rotary switch to the R
2. Use the L and PE (red and green) terminals for this test.
3. Use the F4 to select the test voltage. Most insulation testing is performed at 500 V, but
observe local test requirements.
4. Press and hold
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, the actual 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.
