Click Mode Operating Instructions 10-13
10.7.3 Determination of N
As required by the standard, N may be determined either by counting the
clicks, or by counting the switching operations.
Select Clicks if N has to be calculated on the number of clicks, or select
Sw.Op.+ or Sw.Op.- to determine N on the number of switching
operations, going up and down the list of the available options in terms of
switched current: 10mA; 20 mA; 50 mA; 100mA; 200mA; 500mA; 1A; 2A
and 5A. The current threshold value must be chosen in relation to the DUT
declared consumption.
Refer to § 10.9 for the connections to the external Switching Box,
indispensable when you need to measure the switching operations.
10.7.4 Factor f
The applicable standard may require a certain factor f to be used to
calculate the click rate N (see § 9.2.1). For example, table A2 of the
CISPR14 gives the factor f for several products.
This factor depends on the nature of the EUT and shall be entered by the
User in the normal way (see for example §4.2).
10.7.5 Stop on Fail
The Click test may be rather long, as the observation time and EUT cycle
can take as long as 120 minutes.
In order to save time and increase productivity, the PMM 9010 can stop the
test as soon as a fail condition is achieved.
Two options are therefore available: stop immediately as the fail condition
occurs (Right away) or anyway at the End of Step.
Press Change to flip from one to the other option.
