Refer ence Probe (-R models only)
The reference probe section of the user manual explains in detail how to set up the reference
of the calibrator using the front panel keys. The procedure is summarized here.

Probe Connection

A PRT is the only type of probe that is supported by the reference thermometer in
(RTD or SPRT) probe connects to the reference thermometer input using a 5-pin DIN connector.

pins 2 and 4 sense the potential). If a shield wire is present it should be connected to pin 3.
A two-wire probe can also be used with the reference thermometer. It is connected by attaching
one wire to both pins 1 and 2 of the plug and the other wire to both pins 4 and 5. If a shield wire is
present it should be connected to pin 3. Accuracy may be significantly degraded using a two-wire
connection because of lead resistance.
