Resistive temperature probes (Temperature)
Display the MEASUREMENT MENU dialogue box:
Select the Rt measurement function, then the appropriate "type of probe" using the function and navigation keys.
Select Auto, 2 -Wire, 3-Wire or 4-Wire connection with the function and navigation keys.
Select display unit.
Confirm with ENTER.
Connection is made according to the number of wires of the resistive probe.
The following probes are available:
Sensor
Pt 50 (α = 3851)
Pt 100 (α = 3851)
Pt 100 (α = 3916)
Pt 100 (α = 3926)
Pt 200 (α = 3851)
Pt 500 (α = 3851)
Pt 1000 (α = 3851)
Ni 100 (α = 618)
Ni 120 (α = 672)
Ni 1000 (α = 618)
Cu 10 (α = 427)
Cu 50 (α = 428)
α is the temperature coefficient of the probe.

In order not to introduce an error when measuring with 3 wires, the following is recommended:
Measure using conductors of the same length, the same diameter and the same type of metal (a
difference of 40 m between two wires introduces an error of about 0.1° C).
Take care with the connections to avoid the appearance of interfering contact potential differences.
