Proper storage of leads/unit
After the analyzer 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. Not placing the leads in the nylon, bag and putting
them directly onto the touchscreen can break or damage the screen. If the screen is
damaged, the unit will not operate properly and it will have to be sent to SKF for replacement.
Although these units come with a comprehensive one-year warranty, exterior damage of this
type is not covered.
Take care to keep the unit dry. The analyzer should not be stored in any location where water
entry to the analyzer can occur. Humidity will also affect the operation of the analyzer.
Checking test leads for broken sections
Either prior to using the analyzer or at least once a month, inspect each test lead for broken
sections. If the analyzer has a broken lead, it will not work properly and could yield erroneous
results. The typical spots where leads break are within the first six inches from the analyzer
panel strain-reliefs and 12–18 inches from the clips. There are two methods to check for
breaks in the leads: a manual check and an overcurrent trip test.
Manual break check
1) Inspect the lead wire for any cuts or nicks in the wire sheath.
2) Take the clip in one hand and grip the lead wire in the other had approximately 12–
18 inches from the clip.
3) Grip the lead wire approximately six inches from the strain relief on the analyzer.
4) Steadily, pull the lead. If the lead stretches, it is broken. If it does not have any give,
it is good.
Overcurrent trip test
The black ground lead is the most commonly broken lead. This is an easy test to verify if the
black lead is broken.
1) Connect all leads together (clip to clip) (three red, one black ground).
2) Place analyzer in either Meg-Ohm or DC HiPot mode. Initiate test.
3) If the analyzer immediately shows an overcurrent trip, the black test lead is good. If
the analyzer continues to ramp up to the test voltage, the black test lead is broken.
Open circuit test to verify analyzer operation
While doing periodic testing, there are some instances that the analyzer will immediately trip
when first initiating testing. When this occurs, there is generally some question by the
operator if the motor is truly bad or if the analyzer is operating correctly. A simple open circuit
test verifies analyzer operation.
1) Unhook all leads from the motor being tested.
2) Store all leads in a safe place: on the floor, over the edges of a plastic trash can, and
so on. Ensure that the test clips do not touch.
3) Place the black lead away from the red leads.
