Controller (TT)
Calibration bath (TM)
The ATC (Absolute Temperature Calibration) function serves to
calibrate the working sensor.
 Place the working sensor "A" and the temperature sensor of a
thermometer in the calibration bath.
 Determine the difference temperature (∆T=TM - TT)
and store as correcting factor (example ∆T = -0.26 °C) as
follows:
 With the edit keys change the menu function from
"Atc 0" to "Atc 1" and then press enter .
 Using the cursor keys and the edit keys
set the correcting factor (example -0.26 °C) and then press
enter
.
After exiting the menu level, the corrected value (example: 36.7
°C) is indicated on the MULTI-DISPLAY (LED).
Recommendation
:
In case a calibrated temperature measuring instrument is used, the
ATC function allows the controller to be used as testing instrument
according to ISO 9000.
