Measurement
Examine the test sample.
o
Determine the necessary measuring points before
starting the test.
Select the testing current.
o
Select the testing current by
touching the line shown on the left.
Measurement
1 Move the test probe to the first contact point and apply it.
2
Tap the “
Start
” button.
o
Observe the measured value on the display
(the highest measured value will be saved).
3
Tap the “
Pause
” button.
4 Move the test probe to the next contact point and apply it.
5
Tap the “
OK
” button.
o
Observe the measured value on the display
(the highest measured value will be saved).
Repeat measuring steps
3
to
5
to measure at further contact
points.
During the measurement, move all movable
individual parts of the protective conductor
section.
Pay attention to a proper contact of the
o
alligator clip(s) or test probe and
o
all terminal and plug connections.
If there is a significant change of the measured
resistance value when the protective conductor is
moved, it must be assumed that the protective
conductor is not properly connected or damaged or that
one of the terminal or plug connections has lost contact
with the test sample.
Tap the “
Stop
” button when you have scanned all
accessible conductive parts of the test sample by
means of the test probe that are connected to the
protective conductor.
The “
Test result
” screen opens.
Measuring errors
If you lose contact with the test sample during the measurement,
the circuit will be interrupted.
The maximum value of
> 30,000
Ω
is shown on the display of the
appliance tester.
The test will be considered as failed.
15.2.4.1 Troubleshooting
1 Establish a proper connection between the test probe and the
contact point of the test sample.
2 Then tap the "
Reset
" button while the measurement is active
or running.
The maximum value will be overwritten by the currently measured
value.
If the
measured value
is lower than the current
limit
, the test is
passed.
