General Settings
(Setup: Auto Measurements parameter)
The following settings can be entered for all test sequences with
the rotary switch in the
SETUP
position on menu page 1/3 under
the
Auto Measurements
parameter:
Automatic Measurements (1/7)
❑
At the End of the Sequence
Determines whether the main window with storage option
(“memory screen”) or a report with test results (“results list”) is
displayed at the end of a test sequence.
❑
Considering Measuring Uncertainty
If
Yes
is selected, measuring uncertainty is taken into consider-
ation when the measurement results are displayed. The final
result which appears at the display is downgraded by an
amount equal to measuring uncertainty.
❑
Auto Measuring Point
If
Yes
is selected, the test instrument detects whether or not
the protective conductor is contacted with the probe during
the protective conductor resistance measurement of an auto-
matic test sequence and automatically starts recording a new
measuring point. Statuses are indicated by various, continu-
ous acoustic signals. The protective conductor test can thus
be conducted without using the keys on the test instrument.
Note
The “Auto Measuring Point” function is only activated
during test steps of the “multiple measurement” type. If
you want to use this function ...
– In the case of integrated test sequences: make sure
that “multiple
measurement is selected for the RPE test step.
– In the case of user-defined test sequences (only with
the SECUTEST DB+ database extension – Z853R or
feature KB01): make sure that the RPE test step
has been entered to the sequence as a “multiple mea-
surement”.
Automatic Measurements (2/7)
❑
Initial Window Style
Selection can be made here between a tree view and a detail
view for the first page of the test sequence (see section 17.2).
❑
Auto Mains Off
Automatic test sequences detect whether the DUT is
switched on or off.
DUT is off: test sequence is continued automatically (without
pressing any key on the test instrument).
DUT is on: as soon as the DUT is switched off by the user,
mains power is also automatically switched off at the DUT.
The test sequence is then continued automatically (without
pressing any key on the test instrument).
Attention!
!
The function is NOT suitable for DUTs for which a sys-
tematic shutdown procedure is required (e.g. desktop
PCs).
On/off detection is based on current consumption at the
device under test. If momentary current consumption
falls below a certain threshold, the test instrument dis-
connects the DUT from the mains without user confirma-
tion (and continues with the test).
This function should only be activated for DUTs which
are not vulnerable to unprepared disconnection from
mains power.
❑
Startup Instruction
Specifies whether or not the test message “Start up DUT now
and then confirm” is displayed after mains power is switched
on during active testing.
Attention!
!
Erroneous Measurement Results
The DUT must be fully operational during leakage current
measurements.
If the instruction is deactivated, the user must immedi-
ately place the DUT into full operation without being
asked to do so (after mains power to the DUT has been
switched on). An erroneous value would otherwise be
obtained during the following leakage current measure-
ment.
In case of doubt, the measured leakage current value
must be verified with the rotary switch in the IPE or IE
position.
Attention!
!
Deactivate instruction for experienced users only /
deactivate instruction for “on/off” DUTs only.
The DUT must be fully operational during leakage current
measurements because measurement results will other-
wise be incorrect (see previous warning).
For this reason, the instruction should only be deacti-
vated if:
- The DUT can be switched on fully within 3 seconds (ex-
amples: lamps, handheld tools, power supplies, monitor
screens etc.)
- If the inspector is very experienced and thus knows at
which point in time during the measurement the device
under test must be fully switched on.
Automatic Measurements (3/7)
❑
Limit Value Mode
If you want to use only the limit values specified in the stan-
dards to evaluate the measurements, set the parameter to
Normal
.
When set to
Expert
, the
LIMIT
softkey appears next to the
“measurement failed” popup if the measurement has not been
passed. 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), in order to allow the test to
be passed under these new conditions.
Note
Entry of a user defined limit value isn’t possible if “Con-
tinue” is selected for the “Limit Violation” option.
❑
In Case of Limit Value Violation
(only with SECUTEST DB COMFORT – Z853S or feature
KD01)
With its “
Try Again
” operating mode, the test instrument makes
it possible to immediately restart the failed test step and repeat
the measurement in the event that a limit value is violated.
In the “
Continue
” mode, the test instrument doesn’t terminate
the test sequence in the event of a limit value of violation, and
instead continues testing despite any individual steps which
have failed.
