MDtest (100-140 V) - User’s Manual 4 Measurements
4.6 Leakage current from the Application parts according
to EN 62353
4.6.1 Alternative method - IaltPat
Figure 11: IaltPat measurement
Do not touch the exposed conductive parts of the tested appliance while
measurement is in progress – RISK OF ELECTRIC SHOCK!
The test voltage is max. 127 V / 50 or 60 Hz and the short circuit
current is approximately 1.5 mA.
Leakage current measurement is also possible if the MDtest is con-
nected to the IT mains.
Procedure:
• Press the [2 IALT] key and release it.
• Connect the tested appliance: plug in its mains plug into the Test Socket 1
and plug the applied part into the PAT terminal. If necessary (e.g. protective
class II appliances), plug the test lead into the PE terminal.
• Switch on tested appliance’s mains switch.
• Press the [TEST] key.
• Press the test tip against the exposed conductive part of the tested appliance.
• The last measured value is displayed after finishing off the measurement.
• Switch off the tested appliance’s mains switch.
If the measured value is <0.100 mA, then the resolution can be in-
creased. For higher resolution press the [4/5 D] key.
This setting is not saved.
