Commissioning and Operation
4.3.5 Integrated Measuring Instrument
Applies to calibrators with integrated measuring instrument:
Connect device under test
 Connect the cable ends with terminal connectors or the thermocouple adapter to the ap-
propriate inputs.
 Connect the cable screen to the earthing socket if necessary.
Connect device under test with standard signal (mA or V)
 Connect the temperature sensor to the integrated measuring instrument as follows:
3-wire device under test with voltage sup-
ply via calibrator
2-wire device under test with voltage sup-
ply via calibrator
2-wire device under test without voltage
supply via calibrator
3-wire device under test with voltage sup-
ply via calibrator
2-wire device under test with voltage sup-
ply via calibrator
2-wire device under test without voltage
supply via calibrator
Attach clamp-on ferrite
If your sensor cable has no cable screen and the measurement result is affected by electro-
magnetic interference, we recommend using a clamp-on ferrite. Clamp-on ferrites are suita-
ble in which the sensor cable can be inserted with a winding and whose damping properties
match the interference frequency.
 Place the sensor cable with a winding in a suitable
clamp-on ferrite.
 Attach the clamp-on ferrite as close as possible to the
connectors of the measuring instrument and close the
clamp-on ferrite.
Open clamp-on ferrite
 Open the clamp-on ferrite with the supplied ferrite key.
