Sub-leakage measurement procedure
Select the
Sub-leakage
function.
Set test parameters / limits.
Connect test leads to SUB1,SUB2 terminals on the instrument, then connect test leads to
device under test, or
Connect device under test to mains test socket. For Isub-S test, additionally connect test
lead to P/S terminal on the instrument, and then connect test lead to a device.
Start measurement.
Measurement can be stopped manually or by timer.
Save results (optional).

Note:
When P/S probe is connected during the Sub-leakage measurement, then the current
through it is also considered.

YES: The instrument measures leakage current in two sequential
steps with 5 s delay in between. The phase voltage is firstly
applied to the right live output of the mains test socket and
secondly to the left live output of the mains test socket.
