Temperature Measurement By Pt100 - HBM ClipX Bedienungsanleitung

6.6.5

Temperature measurement by Pt100

With the ClipX, temperatures can be measured in degrees Celsius, Kelvin or Fahrenheit
using a Pt100 resistor. The cable resistance is adjusted by way of the sense line.

When using TEDS, measurements are initially always in °C. However, you
can set a different unit via your web browser's Amplifier menu. Any conver-
sion template in the TEDS is not evaluated.
