serves calibration of an external Pt100 sensor.
 Immerse the external Pt100 sensor and a calibrated thermometer
together in a calibration bath at 50°C, for example, and allow the
reading to stabilize.
 Read the temperatures of the calibrated thermometer (T
M
) and the
external Pt100 sensor (T
ExtIst
) in their respective displays.
 Calculate the temperature difference and enter and set this difference
value as the ATC external compensating parameter. (Example: T = T
ExtIst
- T
M
= 1.22 K)
 Use the keypad to enter the desired compensating value
(e.g. 1.22 °C) and set with enter .
Important:
The ATC function remains active until reset to 00.00 °C..
