This procedure describes the method of trimming the Splash-Proof

Thermapen at a single temperature point (32°F/0°C) by using a properly

made ice bath. The Thermapen should rarely need adjustment and

should only be performed if absolutely necessary.

Materials Required:

A coin to open the Thermapen battery compartment (USA nickel works

best)

Large kitchen cup (preferably 1 quart/1 liter size)

Crushed ice (enough to fill cup)

Paper clip

Determining if Your Thermapen Requires Adjustment:

1. Make a proper ice bath by following these steps:

a. Fill a large cup with crushed ice.

b. Add just enough water into the cup to fill in the gaps in ice so no ice floats off the bottom of the cup. Too

much water will cause errors.

c. Stir gently and wait approximately 1 minute.

2. Set the Thermapen display to read temperature in tenths (example: 32.1°F) of a degree.

If the display is set to read temperature in whole degrees (example: 32°F), change to tenths by following these

steps:

a. Turn the Thermapen off by folding the probe away and locking it into the probe retaining slot.

b. Using a coin with the appropriate thickness open the battery compartment.

c. Locate the switch bank directly above the batteries numbered 1 through 4.

d. Move switch 2 to the ON position by pushing the white switch forward and away from the number 2 using

the tip of an opened paper clip.

e. Replace the battery compartment and open the probe to confirm that the display now reads in tenths of a

degree (example 32.1°F).

3. Test the Thermapen display using the ice bath following these steps:

a. Turn the Thermapen on by opening the rotating probe.

b. Insert the tip of the metal probe into the ice bath about 2 inches (50mm) maximum.

c. Stir gently so the tip does not rest on any ice. While stirring observe the displayed reading after about 15

seconds.

d. Once the display is stable and no longer changes, write down the reading. You’ll need this if the

Thermapen requires adjustment.

4. Determine if an adjustment is necessary.

If the reading from the ice bath test is within acceptable limits: 31.3°F and 32.7

°F (-0.4°C and +0.4°C); then

no adjustment is necessary.

b. If the reading is outside of acceptable limits proceed to making the trim adjustment.
