Description
The output voltage or current of
the UUT is too low.
The output voltage or current of
the UUT is too low.
The output voltage/current of the
UUT is too high for the High
current setting of the 9100.
The output voltage/current of the
UUT is too high for the 9100.
The output amplifier of the
Option 135 has become saturated.
The Option 135 has an output
voltage compliance of 1350VDC.
You have attempted to connect
the negative terminal of your UUT
to the HI terminal of the 9100, or
you do not have a complete circuit
connected.
Action
Ignore if you do not have the TEST button pressed
(the 9100 has no way of recognising this), or press
the CHANGE CURRENT key to re-scale the 9100
for a lower current/voltage input signal (N.B. This
should NOT be necessary if using a ‘standard’
insulation type tester).
If you do not have the TEST button pressed, press
the CHANGE CURRENT key to restore default
(SuperI) current setting. If you do have the TEST
button pressed, check the connections to your
instrument as there is no current path. If the
connections are OK, there is a fault with your
insulation tester and it is not supplying sufficient
output voltage for the Option 135 circuits to operate.
Press the CHANGE CURRENT key to restore
SuperI current setting (this is the default current
setting).
Release the TEST button immediately. The output
current of the UUT is too high for the Option 135.
Release the TEST button immediately. Check that
the maximum output voltage of your UUT is less
than 1350VDC.
Check the connections to the instrument are correct
(check you have no short circuits or faulty leads).
Check that you have correctly wired the UUT to the
Model 9100.
