5.6 Using circuit breaker
created in CABA Win
Breakers created in CABA contain less information
than breakers created in the instrument. Therefore,
the missing information has to be added when
importing a CABA breaker to the instrument unit.
This addition of information is done only when it is
required, i.e. the first time a breaker is imported to the
instrument.
The added parameters will initially get default values
according to below. After completed import the user
has to go through the values under the Breaker View
tab. The user can change some of the values, see
table next page.
Note If a breaker that has been located in the
instrument is exported to an old version of
CABA there is a risk that some information
get lost. In this case the user will be notified
that default values are added and that he has
to check all the settings again
When a CABA breaker is imported to the
instrument the attached test plan is changed
to a non-edible type, which means that it
can neither be altered in CABA nor in the
instrument regarding number of contacts etc.
The reason behind this is that changes might
destroy the possibility to compare old test
results with new. However, still speed calcula-
tion points can be edited in CABA.
