11 Measurements – Selector Switch Settings for Standards
If measurements need to be performed in accordance with given stan-
dards which require specific tests, and if results need to be documented
with a test report, an automatic test sequence is advisable instead of indi-
vidual measurements.
➭ Connect the SECUTEST
®
SII to mains power.
A mains connection test is initialized (see chapter 3.2 on page 10).
➭ Connect the DUT to the test socket at the SECUTEST ®
SII (see chap-
ter 7 on page 14). The test instrument initializes connection type
recognition.
➭ Set the selector switch to the appropriate standard.
If the test instrument is equipped with features B00, 01 or 03, and if
the DUT has been connected to the test socket, safety class recognition
is performed. Otherwise, the safety class must be specified manually.
Move the cursor up into the third line in the initial window with the
key, and acknowledge with the key. A safety class can now be
selected with the and keys and acknowledged with the key.
➭ The test sequence can be configured in the Setup… menu, limit values
can be changed if necessary and database options can be selected.
➭ The test sequence is started by selecting Start test and acknowledging
with the key (see following chapter, “Test Sequences”.
Tests which have already been included in chapters 9 through 14 are not
described here again. The only exception is measurement of extension
cables.
11.1 Test Sequences
Test sequences for the various standards are always run in the same
order, assuming that the device under test has been properly connected
and the mains connection test has been passed.
The test sequence can be run step by step with manual activation of each
subsequent step if this function has been specified, or automatically. Step
by step manual operation can be selected if “Manual Sequence” has been
activated under Sequence... in the setup menu in the initial window.
• Visual inspection: If “Visual Inspection” has been activated under
Sequence …
If a part is recognized as defective by the user, it must be identified as
such by selecting it with the cursor and acknowledging with the
key.
• Protective conductor measurement (for SC I devices under test only)
Note
☞
If a protective conductor connection is not possible, the mea-
surement can be skipped with
(when the message „Connect
probe to protective conductor“ is shown on the display).
• Evaluation of protective conductor testing
• Insulation resistance measurement
DIN VDE 0751:
Only if ISO-R is activated under Sequence
…
in the setup menu
DIN VDE 0702: Only if ISO-R is activated in the initial window
• Evaluation of insulation test
• Leakage current measurement
• Evaluation of each individual leakage current measurement
• Evaluation of the overall test
• Perform function test if required:
The function test can be performed each time a safety test has been
successfully completed. The blinking signal lamp indicates that the
function test should be started. Beyond this, the function test can also
be started from the Function Test selector switch position. See chapter
10 on page 24 regarding performance of the function test.
• Display test results
(the worst measured values for the test sequence)
• Save test results and print if required
