Temperature Probe Calibration
If you have replaced the temperature probe for any reason or require greater accuracy the NTC
temperature probe can be quickly calibrated:
1.
Enter the menu by pressing Select (
⏎
)
2.
Use the Up or Down arrows to navigate to
Settings
and press Select (
⏎
)
3.
Use the Up or Down arrows to navigate to
2-point calibration
and press Select (
⏎
)
Once in the 2-point calibration mode set up two glasses of water. Ice water to one glass and add hot
water to the second glass.
Calibration Point 1
Insert the temperature probe of the RAPT Temperature Controller into the glass of ice water while
simultaneously measuring the temperature of the ice water using a calibrated external thermometer
such as a digital instant read thermometer (KL23320). Wait for the temperature reading on both the
RAPT Temperature Controller and the external calibrated thermometer to stabilise as much as
possible.
Then adjust the temperature shown on the RAPT Temperature Controller to match the temperature
measured on the external calibrated thermometer.
Press Select (
⏎
)
to lock in this calibration point 1 and move on to calibration point 2.
Calibration Point 2
Insert the temperature probe of the RAPT Temperature Controller into the glass of hot water while
simultaneously measuring the temperature of the hot water using a calibrated external
thermometer. Wait for the temperature reading on both the RAPT Temperature Controller and the
external calibrated thermometer to stabilise as much as possible.
Then adjust the temperature shown on the RAPT Temperature Controller to match the temperature
measured on the external calibrated thermometer.
Press Select (
⏎
)
to lock in this calibration point 2.
Once both calibration points have been set the NTC temperature probe has been calibrated.
