Making the Thermapen Trim Adjustment:
After determining that your Thermapen requires adjustment by following the
above procedure, follow these steps to trim the Thermapen:
1. Turn the Thermapen off by folding the probe away and
locking it into the probe retaining slot.
2. Calculate the trim adjustment value by subtracting the reading
written down in Step 3 of ‘Determining if Your Thermapen Requires
Adjustment’ from 32.0°F (or 0.0°C).
Example:
• Reading from my Thermapen = 32.9°F
• Adjustment Value: 32.0°F - 32.9°F = –0.9°F
3. Using a Philips screwdriver, remove the battery compartment to access the Set and Menu buttons.
4. Open the probe to turn on the Thermapen.
5. Hold down the menu button for 5 seconds until ‘SET TRIM’ is displayed. Press the Set button until the target trim
adjustment value is displayed. Note the trim adjustment value range is from –3.6°F to +3.6°F (-2°C to +2°C).
6. Press the Menu button to save the trim setting, ‘END’ is displayed for 1 second before returning to normal operation.
7. Retest in the ice bath to confirm that the new reading is within the acceptable limits: between 31.3°F and 32.7°F (–0.4°C
and +0.4°C). If the reading is still outside of the acceptable limits, redo the trim adjustment by following steps 1 through 7.
