To configure the arc detect sensitivity, press the "CNFG" key and select the "SAFETY" option and then the “ARC” option. The
arc detection feature enables the 944i to sense the presence of arcing before catastrophic damage occurs to the DUT. The arc
detection prompt will appear as follows:
SET ARC SENSITIVITY
FAST MED SLOW OFF
This menu allows the user to set the threshold for arc detection. "FAST" sensitivity means that the unit will trigger on lower
amplitude, short duration spikes, while the "SLOW" sensitivity setting requires greater amplitude, longer duration spikes to trigger
the arc detection circuit.
