Customizing your Thermapen®

You can personalize your Splash-Proof Thermapen™ by changing the factory default settings, including:

  • Changing the display units from °F to °C
  • Changing the display resolution from 0.1° to 1°
  • Disabling the auto-off feature

To make any of these changes, open the battery compartment (see How to Change the Batteries) and, using the tip of a bent paper clip, flip the appropriate switch:

Switch 1: Display Units

The factory setting for your Thermapen display is for °F. To display °C, move the switch numbered "1" to the "off" position—towards the batteries.

Thermapen SwitchesSwitch 2: Display Resolution

The factory setting for your Ther- mapenTM display is to show tem- peratures to tenths of a degree (0.1°) for both °F and °C. To change to whole numbers (1°), move the switch numbered "2" to the "on" position—away from the batteries.

Switch 3: Disable Auto-off*

The factory setting for your Ther- mapen is with the auto-off feature enabled. This means your Ther- mapenTM will turn itself off ten minutes after you extend the probe

and turn it on, to preserve battery life. Once off, you will have to close the probe and extend it again to turn the Thermapen back on. To disable this auto-off feature while taking lengthy readings, move the switch numbered "3" to the "on" position—away from the batteries.

Switch 4: Trim Adjust

This feature allows you to set an offset that will automatically add or subtract a number of degrees from your Thermapen readings. It should NOT be needed for normal use.

* Remember, with auto-off disabled, your Thermapen will stay on and continue using battery power if you forget to close the probe.
