7.4 Measuring contact current (IL)
Before performing this measurement, the protective conductor resistance test,
in clause 7.1, must be first performed and passed. Contact current measurement
to be performed instead of insulation resistance measurement for Safety class ll
devices, or for Safety class l devices with exposed conductive parts which are
not connected to the protective conductor. (see Fig.17)
(1) Connect the DUT to the mains outlet. Be sure to connect the same
mains outlet to which the instrument is connected.
(2) Set the range switch to the "IL 2mA" position.
(3) Connect the RPE - Test lead with probe to PE/2mA terminal.
(4) Power the DUT on.
(5) Contact exposed metal parts at the DUT with the test probe.
(6) Read the measured value in "mA" from the LCD.
Result
For Safety Class l, I(with heating elements), and II devices, according to DIN
VDE 0701, Part240, measured values may not exceed 0.25mA, and may not
exceed 0.5mA according to DIN VDE 0701 as well.
This instrument has LED indications which illuminate when the resulting
measurement is below the DUT threshold value of 0.25mA or 0.5mA.
CAUTION
● The mains outlets to which the test instrument and the DUT are
connected must be connected to the same mains outlets.
● Contact current measurement must be performed with the mains plug
poled in both directions. The larger of the two measured values applies.
● A defect in the DUT may cause tripping of the residual current circuit
breaker during testing, which would also result in interruption of supply
power. Data must be backed up before making measurements at data
processing equipment.
