Operation Manual

GMC-I Messtechnik GmbH 9
To test your ohmmeter, proceed as follows:
1 Connect the two probes of your measuring instrument to
the test sockets B1 and B2 (blue and black socket), if you
whish to select the 1  resistor.
2) Connect the two probes of your measuring instrument to
the test sockets B3 and B4 (blue and black socket), if you
whish to select the 50 m resistor.
3) On your ohmmeter, select the desired measuring range
according to the operating instructions of your ohmmeter.
4) Perform the resistance test.
5) Read the measured value on your measuring instrument.
6) Check that the displayed value corresponds to the value
selected on the ISO-Kalibrator 1, taking into account the
tolerances of the ohmmeter.
The resistance value at a time is given on the resistance
symbol which is correlated with the test sockets. You
should use this value as a comparison value. It was individ-
ually determined for your ISO-Kalibrator 1.
7) Conclude the measurement and put the ISO-Kalibrator 1
into an electrically dead condition.
8) You now can select another test resistor and start a new
test, or disconnect your measuring instrument from the
ISO-Kalibrator 1.
9) Do not on any account remove the probes in live condition.
