B.2.8 Resistive Temperature Probes (Temperature) - AOIP CALYS 50 Mode D'emploi

B.2.8 Resistive temperature probes (Temperature)
Display the MEASUREMENT CONFIGURATION dialogue box:
Select the Rt measurement function, then the appropriate "type of probe" using the function and navigation keys.
Select the display unit
Confirm with ENTER.
Connection is made according to the number of wires of the resistive probe.
The following probes are available:
α is the temperature coefficient of the probe.
The CALYS 50 / 75 / 100 displays an icon showing the connections used (
for 4 wires) to carry out the measurement. The wiring arrangement is automatically detected by the calibrator.
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 mΩ
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.
