14.2 Example of an Integrated Test
Sequence
Individual test steps can be configured with the sequence
parameters (see operating instructions).
* If the settings of the classification parameters are de-
tected automatically, they’re identified by an orange
border (in this case and ). However, they have
to be entered manually if they’re not automati-
cally detected, or if they’re detected incorrectly.
➭ Connect the DUT to the test instrument
in accordance with the selected test se-
quence.
– Test socket
– Permanent connection
– Adapter
Connection depends on the type of DUT.
For testing extension cords in accordance
with standards: connection to the test
socket via the following adapter
– EL1: for single-phase extension cords
– VL2E/AT3-IIIE: for single and 3-phase
extension cords
The following checks are run auto-
matically before the test sequence is
started:
• Probe check P1 (determines whether or
not test probe P1 is connected and fuse
link P1 is intact)
• Insulation test (whether or not the DUT is
set up in a well-insulated fashion)
• On test and short-circuit test.
In order to be able to detect a short-cir-
cuit at the DUT, testing is conducted
between L and N, as well as LN and PE.
If you’ve set the “ Detected classification ”
parameter for the respective test
sequence to “Always accept” and the
“
Auto-detection of ” parameter to “Con-
nection and SK” (before triggering
Start ), the
following additional checks will be run before
the test sequence is started:
Meas. Parameter Meaning
Standard Test standard / extension cord
Protection category * PC1/PC2/PC3
Connection type * Test socket / permanent /
adapter
Measurement type (MA)
*
Active or passive DUT
(on test:
on = passive, off = active)
Detected classification No auto-detection:
all classification parameters
such as connection, protection
category and measurement type
must be entered manually.
Always accept:
All classification parameters ac-
tivated under “Auto-detection of”
are detected automatically and
accepted.
