2.1.2 - External Probe Connection

Place the 4-wire Pt-100 standard sensor into the insert and plug the mini-DIN

connector to the external probe input (

EXT. PROBE

) located on the calibrator front panel, as

illustrated in the figure below:

The temperature control with the external probe must be enabled by the

PRBe

option of the

PRG

menu. More details in item
