Calibration and Connection of Pt 100 Resistance Thermometer
The Pt 100 input is calibrated in the factory. A new calibration is required only
when the detector boards or the detector microprocessor are replaced.
1. Apply 100 Ω (with lowest tolerance) to Pt 100 input at the detector (terminals
3 and 4, Figure 21).
2. Press <
enter
> until the menu Service Menu/Mass Flow is displayed.
3. Select Service menu with <
sk1
>.
4. Press <

5. Press <
sk2
> (2
nd
softkey) and <

> at the same time. When the display
„Pt 100 calibration running...“ appears, press <
