MI 3152(H) EurotestXC (2,5 kV)
Measurement procedure
Enter the R iso function.
Set test parameters / limits.
Disconnect tested installation from mains supply and discharge installation as required.
Connect test cable to the instrument.
Connect test leads to object under test (see Figure 7.7 and Figure 7.8).
Different test cable must be used for testing with nominal test voltage U
U
= 2500 V. Also different test terminals are used.
N
The standard 3-wire test lead, Schuko test cable or Plug / Tip commanders can be used
for the insulation test with nominal test voltages ≤ 1000 V. For the 2500 V insulation test
the two wire 2.5 kV test lead should be used.
Start the measurement. A longer press on TEST key or a longer press on "Start test"
option on touch screen starts a continuous measurement.
Stop the measurement. Wait until object under test is fully discharged.
Save results (optional).
