5 Measurements
5.1 Insulation resistance
The Insulation resistance measurement is performed in order to ensure safety against
electric shock. Using this measurement the following items can be determined:
 Insulation resistance between installation conductors,
 Insulation resistance of non-conductive rooms (walls and floors),
 Insulation resistance of ground cables,
 Resistance of semi-conductive (antistatic) floors.
For additional information concerning insulation resistance measurements refer to
Metrel’s handbook Measurements on electric installations in theory and practice.
How to perform an insulation resistance measurement
Step 1 Select Insulation function with the function selector switch.The following
menu is displayed:
Figure 5.1: Insulation resistance measurement menu
Step 2 Set the following measuring parameter and limit values:
 Nominal test voltage,
 Low limit resistance value.
Step 3 Ensure that no voltages are present on the item for testing. Connect the test
leads to the EasiPLUS instrument. Connect the test cables to the item under
test. (see figure 5.2) to perform insulation resistance measurement.
