First of all, the digit blinks (here: 1 without icon) until the
measured value is stable. The evaluation cycle is visu-
alized as follows: the progress bar starts at the left-
hand edge of the display and moves to the right. When
it reaches the rightmost position, evaluation has been
completed and the icon shown at the right appears
with the current number.
➭
Depending on whether you want to delete the last
value saved to buffer memory or all values, press the
icon with the wastebasket shown at the right an appro-
priate number of times.
➭
Proceed to the next measurement by pressing the key
shown at the right.
If the measured value appears red at the display, a limit
value has been violated. If you press
, the DUT will not
pass the test unless further measures are implemented.
Various options are available depending on which setting was
selected in SETUP (Auto. Measurements 3/4):
–
Abort: Testing is interrupted and the test is failed.
–
Retry: A popup appears from which either interrupt or repeat
can be selected.
–
Continue: The test instrument continues with the next test
step without displaying any further message.
Note
A test step which is classified as critical generates a
warning.
Caution:
Dangerous Voltage! Do not touch metallic parts.
If the test sequence is continued, accessible parts may
conduct
dangerous voltage
during the test, because the
DUT is operated with mains voltage despite possible
insulation faults, excessive protective conductor resis-
tance etc.
Proceed as follows if you’d like to continue.
1 Wear suitable personal safety equipment (PSE).
2 Secure the DUT against touch contact with a suitable
cover.
3 Use a 30 mA RCD.
4 Continue by pressing

Note
Test Sequence IEC 60974-4 / EN 60974-4 / VDE 0544-4:
Section 5.2 of IEC 60974-4 / EN 60974-4 / VDE 0544-4
expressly stipulates that the cables have to be bent and
twisted over their entire length during the measurement,
in particular in proximity to the cable glands, in order to be
able to detect any interruptions of the protective conduc-
tor.
Test Steps with Automatic Evaluation (R
INS
, I
PE
)
The measured value is ascertained automatically within a speci-
fied period of time. The evaluation cycle is visualized as follows:
the progress bar starts at the left-hand edge of the display and
moves to the right. When it reaches the rightmost position, evalu-
ation has been completed. Depending on the results (see
page 90), the test sequence is then automatically continued or
aborted.
Manual Evaluation of the Function Test
(prerequisite: “function test” sequence parameter is preset to “on”.
➭
Evaluate the function test:
➭
If you mark the function test as not passed with the
softkey shown at the right, the sequence is aborted and the
test is evaluated as not passed.
➭
If you evaluate the function test as passed, you can
simply continue with the test sequence.
In either case you can enter a comment, which can be
subsequently edited as well.
Setting Limit Values Manually
If “Expert” is selected instead of “Normal” in setup under “Auto
Measurements” in the “Limit Value Mode” submenu, the LIMIT
softkey appears next to the “measurement failed” popup. This key
makes it possible to enter a user-defined limit value (as a rule a
limit value specified by the manufacturer which deviates from the
standard):
Note
Selecting “Abort” or “Try Again” rules out the possibility of
entering a limit value.
17.7
End of the Test Sequence
“Sequence finished” appears at the display.
Initial Display (memory screen)
The memory screen display depends on the setting in the setup
menu with the rotary switch in the
SETUP
position:
Setup 1/3 > Auto Measurements 1/4 > At End of Sequence >
Memory Screen
.
If set to
Results list
, the above display is skipped and the results list
shown below is displayed.
You can also access the results list by pressing the key
shown at the right.
