Substitute leakage – S probe measurement procedure
 Select the Substitute leakage-S probe function.
 Set test parameters.
 Connect device under test to the instrument (see figures above).
 Connect EB/S probe to accessible conductive parts of the DUT.
 For fixed equipment:
 Disconnect mains supply of the fixed equipment;
 Connect LN test socket of the instrument to L/N terminals of the fixed equipment;
 Connect EB/S probe to accessible conductive parts of the fixed installed DUT
 Press the START key for measurement.
