Touch leakage current - IdirTouch / IdifTouch / IdirW
WARNING
Touch leakage currents are measured by the same measurement meth-
ods as leakage currents which are specified in chapter 4.6. Therefore,
all safety warnings and operating instructions apply for these measure-
ments as to those measured leakage currents listed in chapter 4.6.
4.7.1
Protective class II appliances
Procedure:
•
Press the
[5 I
DIR TOUCH
]
key (direct method) or the
[8 I
DIF TOUCH
]
key
(differential method).
•
Press the
[5 I
DIR TOUCH
]
or
[8 I
DIF TOUCH
]
keys repetitively in order to
measure with L-N reversal. Symbol L-N reversed is displayed.
•
Connect the tested appliance: plug in its mains plug into Test Socket
1
.
•
Plug the test lead into the
I
TOUCH
terminal.
•
Press the
[TEST]
key.
•
Switch on tested appliance’s mains switch.
•
Press the test tip against the exposed conductive part of the tested appliance.
•
The HOLD function can be used (press the
[
H
]
key).
•
Switch off the tested appliance’s mains switch.
•
Finish the measurement (see chapter 4.2.1).
4.7.2
Protective class I appliances
The same measuring circuit is used to measure the touch current and
the leakage current. The instrument measures simultaneously both
the leakage current and the touch current. To determine the leakage
current and touch current value for Class 1 appliances, first measure
the protective conductor current and then the touch current. The
displayed value is the sum of the leakage current and the touch current,
and this data can be stored in the device memory.
If you only want to measure the touch current (and not the sum of the
current by the protective conductor and the touch current), connect
the DUT directly to the mains socket (not to the Test Socket 1).
The measurement procedure is the same as the procedure in the chapter 4.7.1.
