9.7 Test Execution
The selected test mode can be started by pulling down the Run menu and selecting All or by
clicking on the Start button. During test execution, no changes to test parameters are allowed.
The test progress can be monitored at the bottom of the window in the status bar.
9.8 Test Parameter File Creation and Limits
New tests can be created by editing the data entry grid. The following test parameters are
available for each test step. Note that the number of test steps is limited to 100 steps which
should be more than adequate to cover any possible product standard.
Field Description Range
Unom (%) Specifies the percentage of Unom to use for this test step.
Typical values are 100 %, 110 % and 90 % for a 0, +10 and
-10 change. 50 to 150 %
Test Level (%) Specifies the percentage change from Unom to apply for
this test step. Test levels are defined for different product
classes. -20 to +20 %
Level Repeats Number of times specified test level is applied at this step.
Normally, this value is set to 3. Each test level is applied for
2 seconds and repeats in 5 second window. The rise and
fall times are set to 5 cycles each. 1 to 100
Delay (s) Time is seconds between successive repeats of this test
step. 0.1 to 999.9 sec.
Repeats Number of times this test step is repeated. Normally, this
value is set to 3. 1 to 100
9.9 Test Results
There is no way for the CIGUI to determine the outcome of this test as a clear definition of a
failure can not be given. The draft standard called out the following possible test results:
“The�test�results�shall�be�classified�on�the�basis�of�the�operating�conditions�and�functional�
specifications of the equipment under test, as in the following, unless different specifications are given
by product committees or product specifications.
a) Normal performance within limits specified by the manufacturer, requestor or purchaser
b) Temporary loss of function or degradation of performance which ceases after the disturbance
ceases, and from which the equipment under test recovers its normal performance, without
operator intervention.
c) Temporary loss of function or degradation of performance, the correction of which requires
operator intervention.
d) Loss of function or degradation of performance which is not recoverable, owing to damage to
hardware or software, or loss of data.
As a general rule, the test result is positive if the equipment shows its immunity, for the duration of the
application of the test, and at the end of the tests the EUT fulfills the functional requirements
established�in�the�technical�specification.”
The user has to make this determination by observing the
unit under test. At the end of a test run, the following
dialog box is displayed. Click on the Help button to
display the pass/fail criteria shown above.
9.10 Report Format- 414 Test Files
The IEC 61000-4-14 test module produces a test report when the Print Report button is clicked.
Reports can also be printed from the File, Print menu. Test reports include all selected test
parameters and options. A sample test report is shown below. The report format used can be
