4.7. Special functions

With regards to the setting of the protection parameters is possible to carry-out
several tests by using different settings and curves to identify the optimum program
for the circuit breaker/installation .
The test unit can memorise a special "frequent use" program for each of the
protection units that may be electronically programmed (Define default).
The manual test function also enables a general current to be introduced into the
release in order to test the trip time (a particularly useful function for selectivity
studies between two or more circuit breakers).
