Adjust Current
Limit
Off Line Adjustment: Use the Current Limit Test (Off Line) to
verify that the current limit circuit needs adjustment, before
continuing with this procedure.
Amps
± 2.5% of reading ± 2 amperes*

To compare, measure the shunt voltage. 1mV of shunt voltage indicates
5 amperes of output current. For example, the shunt voltage should be
40 mV at full load (200 amperes). At 125% of full load (250 amperes),
the shunt voltage should be 50 mV.
