1. Connect the sockets "PT100" and "PT1000" of the 773 pH/mV
Simulator with the temperature measuring input of the instrument
with separate 6.2150.000 Cables.
For instruments with DIN plugs (e.g. 670, 636) use 6.2150.010 Cable.
2. Set the instrument being checked to temperature measurement.
The measured value should be approx. 0 °C (exact value given in
the table - field PT100/T and PT1000/T).
3. Plug the cables into the 773 pH/mV Simulator as follows:

The measured value should be approx. 25 °C (exact value given
in the table - field Add.data, red).
This check is not possible for instruments which can only measure with Pt100
(e.g. 670, 636).
Please take into account both the resolution of your instrument’s
display and the information about tolerances given in the
‘Instructions for Use’ for your instrument.
