If the display still shows no voltage bar, call the service department. Use a meter to confirm
the insulation resistance of the device being tested.
Current bar operation can be tested by shorting test lead 1 and the ground lead together.
Under this condition, the voltage bar will not move off the zero line and the current bar
should rise very rapidly and activate the hipotovercurrent trip warning light (hipot trip). If the
hipot trip light does not light, check for open test leads at either test lead #1 or the ground
lead (see Open Condition Check). If the problem persists, contact the serviced epartment.
HiPot over current trip check
1) Either the hipot trip lamp does not activate under known shorted conditions, or it will
not go out when test is discontinued.
Call the service department immediately for assistance. Please record information off the
unit and the specific problem prior to calling.
Open ground check
The open ground warning prevents testing.
Answer these questions:
• Has the unit recently been moved to a new location with possibly an ungrounded
outlet?
• Is the unit being operated in a field where the AC power source is unknown?
• Is the unit being operated on a scope cart that has its own outlet or power source?
• Is the unit being operated using a two-wire extension cord?
• Is the unit being operated on a transformer-isolated circuit?
If you answer “yes” to any of these questions, the unit is probably operational and indicating
that there is open AC line ground connection.
In the case of numbers 1–3 above, use an outlet tester to ensure proper wiring connections
to the outlet.
Limited output surge waveform
The display shows a limited output (amplitude) surge waveform. The display rises normally,
but stops at some point. Alternatively, you must continually increase the output control for
successive tests to achieve the same output test amplitude.
Call the service department immediately for assistance on this or any other abnormal
condition noted. Please record basic information from the tester and the specific problem
prior to calling.
Proper storage of leads/unit
After the instrument has been correctly shut down, the high-voltage and resistance leads can
be placed back into the nylon bag with the power cord. This can be carefully placed on top of
the touchscreen and the lid closed for storage. By not placing the leads in the nylon, bag and
putting them directly onto the touchscreen can break or damage this screen. If the screen is
damaged, the unit will not operate properly and have to be sent to SKF USA for replacement.
Even though these units come with a comprehensive one-year warranty, exterior damage of
this type is not covered.
