MDtest (100-140 V) - User’s Manual
4
Measurements
4.6.2
Direct method - IdirPat
Figure 12: IdirPat measurement
If the test voltage is present in Test Socket
1
, then the tested equip-
ment starts to run after its mains switch is switched on! Take into
consideration all safety warnings referred to by the DUT!
Do not touch the exposed conductive parts
of the tested object
after the mains switch is switched on!
The MDtest is equipped with an electronic check for excessive leak-
age current during measurement. If the leakage current exceeds the
limit value of approximately 10 mA, then the mains voltage is discon-
nected from the Test Socket
1
. This status is indicated by displaying
(Current >10.00 mA)
and the acoustic signal sounds.
WARNING
•
The earth bond resistance (chapter 4.3) must be first tested; it
is recommended that you also test the insulation resistance if it
is possible too (chapter 4.4). Then you can carry out the leakage
current measurement!
•
Test Socket
1
of the MDtest must not be used for continuous
power supply of the appliance!
