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.
