The master output will be connected with the CT primary and output pulse current with
setting value.
The slave machine will be connected with the CT secondary side to check the winding
polarity. If there are more than 2 slave machines configured, more CT polarity can be
checked at the same time.
There is magnetic installed inside of the slave machine so it can be attached to the cabinet
for convenience.
During testing, if it is showing the master battery low indication LED on, it is suggested
decrease the master output period and max current or change a new master machine.
