CIBANO 500 PTM User Manual
274 OMICRON
18.2 First Trip test
The First Trip test measures the opening time of the circuit breaker during the first operation after a long
static period. The trip coil current characteristic is automatically recorded and, if spare auxiliary contacts
are available, they also could be included in the First Trip measurement.
Note: To perform the First Trip test, you need a license. Without the license, it is not possible to start the
measurement and Primary Test Manager displays a missing license message. To get the license,
contact your regional OMICRON service center.
