General User Cautions and Notes
•
Irregularities, particularly vertical spikes, may be seen the first cycle of the
surge wave pattern. Therese occur most frequently on large, high voltage
motors. Do not interpret these as faults in the windings. Any winding fault
will be seen throughout the entire wave pattern.
•
DO NOT change the TEST LEAD SELECT (TLS) SWITCH while a test is
being made. Doing so will cause arcing and damage of the instrument’s
components.
•
Do not switch the FUNCTION CONTROL between Surge and HiPot
settings during testing.
