Anomalous Situations - HT PV-ISOTEST User Manual

6.1.4. Anomalous situations

1. To zero the value of compensated resistance, carry out a
new compensation procedure with a resistance higher
than 5 as, for example, with open leads. The message
"Zero Reset" appears on the display.
2. In case the instrument detects a voltage higher than 3V
at its terminals E and C, it does not carry out the test,
gives out a long sound and displays the message "V.Input
> 3V".
3. In case the instrument detects that the calibrated
resistance is higher that the measured resistance, the
instrument gives out a long sound and displays the
message: "Zeroing NOT OK"
4. In case the instrument detects a resistance higher than
5 at its terminals, it gives out a long sound, zeroes the
compensated value and displays the message "Zero
Reset".
5. If the instrument detects a calibrated resistance higher
than measured resistance (e.g. by using test cables
different from the supplied ones) at its terminals, it gives
out a long sound and displays a screen like the one to the
side. Perform a calibration reset with open terminals and
start a new calibration.
