USER LIMITS SETTINGS Screen
This screen allows programming user defined voltage and frequency upper and lower limits
to prevent an operator from accidentally programming output settings that could be
damaging to a unit under test.
For example, when testing a 50 Hz transformer, a lower frequency limit setting of 47 would
prevent output frequency programming of values that could cause the transformer to
saturate.
This applies to voltage where a high voltage value could damage a unit under test that was
not designed to handle high AC input voltage.
