20 Test Sequences (Automatic Test Sequences)
– AUTO Function
Select AUTO Switch Position at the Test Instrument
With the rotary switch in the AUTO position, all of the test
sequences in the device are displayed.
If there aren’t any test sequences in the instrument, NO DATA
appears.
20.1 General (test sequence layouts)
If the same sequence of tests will be run frequently (one after the
other with subsequent report generation), for example as speci-
fied in the standards, it’s advisable to make use of test
sequences.
Automated test sequences can be compiled from manually cre-
ated individual measurements with the help of the test sequence
function.
A test sequence consists of up to 200 individual steps, which are
executed one after the other.
Fundamentally, differentiation is made amongst three types of
individual steps:
•Note (Visual Inspection test step) Test sequences are inter-
rupted when a pop-up message is displayed for the inspector.
The test sequences is not resumed until the message has
been acknowledged.
Sample Message Before Insulation Resistance Measurement
“Disconnect the device from the mains!”
• Visual inspection, testing and report generation: The test
sequence is interrupted when a passed/failed evaluation is
displayed. The comment and the results of the evaluation are
saved to the database.
• Measurement (“User-Evaluated Measurement” test step): same
as individual measurements with instruments with storage and
parameters configuration
20.2 Creation of Test Sequences with ETC
The test sequences are created at the PC with the help of ETC
software, and are then transferred to the test instrument.
Measurement parameters are also configured at the PC. How-
ever, parameters can be changed at the test instrument during
the test sequence before the respective measurement is started.
When the test step is started once more, the parameter settings
specified in ETC are loaded again.
ETC does not subject the parameters to a plausibility check. As a
result, the newly created test sequence should be checked at the
test instrument before it’s permanently added to the database.
Limit values are not currently set in ETC, and have to be adjusted
during the automatic test.
Accessing the Menu for Editing Test Sequences
In order to be able to edit existing test sequences (e.g. add test
steps or change parameter settings), they first have to be loaded
to ETC.
There are two ways to do this:
•ETC: Extras  Test Sequences  Load Test Sequences
(from the file “test_sequence_xyz.seq”)
or
• ETC: Device  Test Sequences  Receive Test Sequences
(from the connected test instrument)
Operating Overview: Creating Test Sequences at a PC
1 Create a new test sequence – enter a designation.
2 Change the designation of the selected test sequence.
3 Duplicate the selected test sequence,
(Copy) is added to the name of the duplicated sequence.
4 Delete the selected test sequence.
5 Create or add a new test step for the selected test sequence.
– Select the test step type from the list to this end and either accept or edit
its designation.
6 Duplicate the selected test step.
7 Delete the selected test step.
8 Change position of the selected test step within the sequence.
9 Select test parameters for the selected test step type from the list.
10 Select a setting for the measuring parameter from the list.
11 Accept change to the measuring parameter.
12 Exit the test sequences menu.
Saving Test Sequences in ETC to the PC
We recommend saving default test sequences, as well as edited
and new test sequences, to the PC or to other data
storage media using the desired filename (test_se-
quence_xyz.seq) with the help of the following menu command:
Extras  Test Sequences  Save Test Sequences. Data loss
resulting from certain administrative operations is prevented in this
way (see following notes).
Due to the fact that only up to 10 test sequences, can be trans-
ferred to the test instrument, no more than 10 test sequences
should be saved to any given file.
Test sequences which have been saved to a file can be reloaded
to ETC at any time by clicking “Extras  Test Sequences  Load
Test Sequences”.
Sequences can be further edited by clicking
“Extras  Test Sequences  Edit Test Sequences”.
Transferring Test Sequences from the PC to the Test Instrument
After executing the following ETC command, all previously cre-
ated test sequences (up to 10) are transferred to the connected
test instrument: “Device  Test Sequences  Send Test
Sequences”.
