Offset/Calibration Function

Using the Offset to Adjust for Probe Errors
Use the offset/calibration option to adjust the meter’s 

readings to compensate for the errors of a specific 

sensor. The allowable adjustment range is ±9.0°F or 

±5.0°C.
1. Plug the probe into the meter’s input connector.
2.  Place the probe in a known, stable temperature 

environment (such as an ice bath).

3. Allow the readings to stabilize.
4.  Adjust the offset until the primary reading matches 

the calibration temperature. 

Adjusting the Offset
The primary display shows the temperature plus the 

offset and the secondary display shows the offset.
1.  Press the CAL button for 3 seconds to enter user 

calibration T1 mode (alarm will sound).

2.  Press the Up (

) or Down (

) buttons to adjust the 

offset by 0.1°. The max offset value is 5°.

3.  Press the CAL button again for 3 seconds to enter 

user calibration T2 mode (alarm will sound).

4.  Press the Up (

) or Down (

) buttons to adjust the 

offset by 0.1°. The max offset value is 5°.

5.  Pressing the CAL button a third time will save the 

settings and return to normal measurement mode.
