6.3  Setting temperature (Set °C°F) sub-function  
1.  Select the “SET °C°F” sub-function, then press the ENT key. 
2.  Selecting temperature unit: press the ▲ or ▼ key to select the desired temperature unit 
“°C” or “°F”. Press the ENTER key to confirm your selection. 
3.  Enable/disable ATC mode: press the ▲ or ▼ key to enable (ATC ON) or disable (ATC OFF) 
automatic temperature compensation. Press the ENT key to confirm your selection. 
−  ATC disabled (ATC OFF): 
For manual temperature compensation you can set the process and calibration 
temperatures. This allows calibration at a temperature other than the process 
temperature. Example: setting a calibration temperature of 25°C lets you calibrate 
using standard solutions at 25°C, even if your process temperature is different from 
25°C. 
4.  Setting the process temperature: press the ▲ or ▼ key to adjust the process temperature 
(upper value, setting range: –10.0 to 125.0°C / 14.0 to 257.0 °F). Press the ENT key to confirm 
process temperature. 
5.  Setting the calibration temperature: press the ▲ or ▼ key to adjust the calibration 
temperature (upper value, setting range: – 10.0 to 125.0°C / 14.0 to 257.0 °F). Press the ENT 
key to confirm the calibration temperature. 
−  ATC enabled (ATC ON): 
6.  Setting the temperature offset: The display shows the current temperature offset (upper value) 
and the temperature currently measured (lower value). Compare the current temperature 
displayed on the transmitter to a thermometer known to be accurate. Note the correct 
temperature value. Press the ▲ or ▼ key to adjust the lower value. The upper number 
indicates the offset value. You can offset the temperature by up to ±10°C/±18°F. Press the 
ENT key to confirm your setting. 
Continue with additional Setup procedures, or return to the Measurement mode by pressing 
the ▲ and ▼ key (escape) simultaneously.
