Figure 4.21: Measurement of Riso, Riso-S (socket)

RISO measurement procedure



Select the

Riso

function.



Set test parameters / limits.



Connect test leads to ISO(+), ISO(-) terminals on the instrument, then connect test leads to
device under test, or



Connect device to mains test socket. For Riso-S test, additionally connect test lead to P/S
terminal on instrument, and then connect test lead to device.



Start measurement.



Measurement can be stopped manually or by timer.



Save results (optional).

Figure 4.22: Examples of Insulation resistance measurement results

Note:



When P/S probe is connected during the Riso measurement, then the current through it
is also considered.
