4.2 Displaying PI and DAR
86
When the resistance indication blinks, the
displayed reading may be incorrect. (Insu-
lation resistance changed rapidly before
end of set specified time, affecting mea-
surement range due to internal circuit fail-
ure to respond)
When the resistance reading blinks, regard
the PI or DAR value as a reference. Per-
form measurement again.
The table below shows special indications
for PI and DAR.
