Program AC test prior, to a calc test
Rezero GC measurements only, indicates that the
calculated GC resistance is less than zero, probably
because of a change in lead set or using rear input
instead of front. Perform Measure Offset
Safety Shutdown This message may result from a ground fault (GFI)
or overload
*SHORT* Current exceeded power amp limit of 25 mA
**SHORT** Current exceeded limit specified for instrument
(20 mAAC, 8 mADC)
***SHORT*** High voltage relay opened because of current
surge. Opening the relay prevents exceeding the
specified maximum current.
****SHORT**** A to D converter overrange, usually results from
too much capacitance in DUT. Add series
resistance to correct
Start ignored, Interlock not asserted
Start ignored, Stop being asserted
Sequence offset invalid, select single step test
Set single step test, currently set to skip
Set single step test, currently set to calc
Test is disabled, program measured param
Test is disabled, program sequence test
Test restored from, defaults correctly
Unable to run – Program, single step test
Unable to set arc detect Arc detect centering failed, connect HV lead to
return lead (to minimize noise) and press STOP
twice.
