Remedy and Reference
When the
instrument is
calibrated, the
accuracy of
the insulation
resistance range
falls outside
the device
specifications.
Has the supplied or
optional test lead used?
Use the test leads that
came with the instrument
or its optional test leads
to perform the calibration
procedure. With standard
wiring, characteristics are
affected when the resistance
in the 1000 V range reaches
or exceeds 100 M
Ω
.
Has the insulation of the
test lead deteriorated?
Replace the deteriorated
test lead with a new one.
*1 Batteries with high internal resistance may not be able to deliver enough
energy to power the instrument, even if you’re using new alkaline batteries
or batteries with sufficient charge. If the instrument does not operate even
though its batteries have just been replaced, try batteries from a different
manufacturer.
*2
Polarity: A phenomenon whereby a substance’s positive and negative
electric charges move in opposite directions when an electric field is
applied to it, causing the center position of the positive and negative
charges to shift.
