ThermoWorks SPLASH-PROOF SUPER-FAST THERMAPEN - Manual (Page 2)

Instrument Configuration
You can personalize your Super-Fast Thermapen by changing several factory default set-
tings including the temperature display units from °F to °C, changing the temperature display
resolution from 1° to 0.1°, and disabling the auto-off feature. To reconfigure these settings,
open the battery compartment (see Replacing the Batteries section for instructions on open-
ing the battery compartment) and, using a bent paper clip, change the switch bank settings
as instructed below.
Switch 1 – Units Changes the instrument’s display units between (°F) Fahrenheit
and (°C) Celsius. The factory default is °F or switch set furthest
from batteries. To change to °C, move the switch to the position
closest to the batteries.
Switch 2 – Resolution Changes the instrument’s display resolution between 1°(F or C)
and 0.1°(F or C). The factory default is 1° resolution or switch set
farthest from the batteries. To change to 0.1° resolution, move the
switch to the position closest to the batteries.
Switch 3 – Auto-Off Enables or disables the auto-off function. If the auto-off function is
enabled (factory default), the unit will automatically turn off after
10 minutes to preserve battery life. If disabled, the unit will remain
on until the probe is folded away and turned off by the user. The
factory default is auto-off enabled or switch set closest to the
batteries. To disable the auto-off function move the switch to the
position furthest from the batteries.
Switch 4 – Trim Adjust If the Thermapen is within specification, we do not recommend
using the Trim Adjust. It should not be needed in normal use. This
mode allows the user to set an offset that will add or subtract up
to 3.6°F (2.0°C) to all readings of the Thermapen. It can therefore
be used to tune the calibration. For detailed instructions visit www.

Calibration
The Thermapen is individually factory-calibrated using very high-precision temperature stan-
dards that are traceable to NIST (national standards). A certificate with actual test data is
supplied with your Thermapen. However, if you have any doubt about its accuracy, you can
check it yourself in a properly prepared ice bath. If it reads correctly in the ice bath, it is almost
certainly accurate at other temperatures.
Making a Proper Ice Bath
Fill a cup or glass with ice. Add just enough water to fill the gaps between the ice. (If the ice
is floating, the water beneath the ice will be at a higher temperature.) After a few moments,
immerse the tip of the Thermapen probe to the middle of the ice and gently stir. Within 3 or 4
seconds the Thermapen will read 32°F within 1°F. Do not let the tip of the probe rest against
an ice cube or it will read a lower temperature (it’s that fast and sensitive). If the reading is
within the published specification, the Thermapen is accurate. You can also test the Ther-
mapen in boiling water but you must first know the correct temperature of boiling water at
your altitude and at the current atmospheric pressure. A calculator can be found at
