Congratulations
The new Super-Fast Thermapen Mk4 is a precision thermometer used for many applications,
including cooking. With proper care, it will offer accurate measurements for many years. The
new Mk4 Thermapen includes several new features, including: intelligent backlight, auto-
rotating display, user-selectable sleep interval, motion-activated wake-up mode, and added
water resistance.
Instrument Operation
The unit is switched on by unfolding the thermocouple probe
until the display comes on. Conversely, the unit is turned
off by folding the probe away and lightly pressing the tip
into the rubber probe retainer located at the bottom rear of
the instrument. It is recommended to store the probe in the
closed position when not in use.
Do not force the probe further than 180° when opening
or damage to the rotating hub may occur.
The micro-thermocouple sensor is located at the tip of the probe shaft. Minimum immersion
is only 1/8" (3 mm). For best results, immerse or penetrate the probe into the food item so the
probe tip is in the place you want to measure. In food, this should normally be at the center
of the thickest part.
The Thermapen will read to within 1°F of the actual
temperature of an ice bath within three seconds. Reading
times in other foods may vary slightly.
Do not immerse the probe all the way to the plastic
rotating hub. Avoid getting flour, moisture, or oil on the
hub itself. Although there is an O-ring seal, oils can
work their way past the seal and accumulate inside
the hub and may cause failure. The probe tip is sharp.
Use caution to avoid injury. Do not “stab” the material
to be measured. Use steady force to penetrate meats
or semi-solids. Avoid bone. Do not lift or flip heavy
meats with the probe tip. The probe shaft is hollow and
contains a sensor. If bent, it may fail.

Operating Instructions
Instrument Configuration
You can personalize your Thermapen by changing several factory default settings including:
Temperature display from °F to °C
Display resolution from 1° to 1.0°
Screen Rotation
Auto-Off/Sleep Mode
To change any of these settings,
loosen the battery cover screw using
a Phillips screwdriver and remove the
battery cover. Open the probe to turn
the unit on. The Thermapen Mk4 has
two small buttons inside the battery
compartment: MENU, which is used
to enter, save settings, and exit the menu; and SET, which is used to select desired settings.
Settings are saved once ‘END’ is displayed at the end of the menu options. To abort settings,
close the probe. Press the MENU button to cycle through the following settings:
Temperature Display Units, °F to °C
Press the MENU button until ‘C or F’ is displayed. Press SET to toggle between
‘°F’ and ‘°Cas displayed in the upper right hand corner of the display. When the
selection is complete, press MENU to store setting.
Display Resolution, 1° to 1.
Press the MENU button until the current resolution setting ‘0.1°’ or ‘1°’ is
displayed. Press SET to toggle between ‘0.1°’ and ‘1°’. When the selection is
complete, press MENU to store setting.
Screen Rotation
Press the MENU button until ‘DISPLAY’ is shown at the top of the display. Press
SET to select ‘360°’ for full 4-way rotation, ‘180°’ for 2-way rotation (horizontal
only), or choose to lock the display in a specific orientation when ‘Loc’ is
displayed. Press MENU to store the rotation setting.
Auto-Off/Sleep Mode
Press the MENU button until ‘SLEEP’ is shown at the top of the display. Press the
SET button to step through the sleep interval settings from ‘10’ seconds to ‘180’
seconds in 10-second intervals, or to turn the sleep function ‘off.’ Press MENU to
store the sleep interval and the unit will enter sleep mode at the specified number
of seconds without movement detected. END will flash momentarily to show that
all settings are saved.
Note: When the probe is open and the unit is in sleep mode, any motion detected
by the Thermapen will conveniently wake the instrument and turn it back on.
When you are done adjusting settings, replace the battery cover and tighten the
battery cover screw with a Philips screwdriver. Do not overtighten.
Calibration
Each Thermapen is individually factory-calibrated using very high-precision temperature
standards 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
MENU
SET
the Thermapen in boiling water but you must rst know the correct temperature of boiling
water at your altitude and at the current atmospheric pressure. A calculator can be found at
www.thermoworks.com/software/bpcalc.html to quickly nd that temperature for your zip
code.
Instructions to use the Trim Adjust to tune your Thermapen calibration are downloadable from
the Thermapen Mk4 web page. A complete You should not need to do this under normal use.
factory re-calibration, including a certificate, is also available from ThermoWorks for a fee.
Intelligent Backlight
When the Thermapen is turned on, a light sensor (small round
window located just to the right of the main display) continuously
monitors ambient light levels. As it gets darker, the intelligent
backlight comes on automatically to read the digits in any light
condition. Covering the light sensor will also turn on the backlight
regardless of light level. The backlight will remain on for a
minimum of 10 seconds. If the unit is displaying the low battery
symbol, the backlight brightness will be reduced to prolong
battery life.
Batteries
Each unit includes one pre-installed AAA
(1.5V) battery located inside the sealed battery
compartment. An illuminated battery symbol ( )
in the LCD display indicates that the battery should
be replaced soon. The instrument will continue to
measure accurately, but it is recommended to replace
the batteries immediately (in low battery condition,
the backlight brightness will be reduced to prolong
battery life). Once the battery is too low to display
readings, the display will be replaced with ‘Flat’ then
‘Bat’ and then shut down. To continue using the
instrument, replace the battery.
Replacing the Battery
The battery is pre-installed on your new Thermapen
Mk4 and should last up to 3,000 hours. Should you
need to replace the battery, loosen the battery cover
screw using a Phillips screwdriver to remove the
battery cover. Pull up on the spring-loaded battery
clip and tip the unit to allow the battery to slide out.
Replace with a single AAA battery noting the polarity (positive goes in rst, retaining clip rests
on negative). Tighten the battery cover screw until the battery cover is snug onto the seal.
Do not overtighten.
Cleaning and Maintenance
To avoid potential bacteria growth and cross-contamination, wipe the probe after each use
and regularly clean the entire Thermapen body. Oils and grease should be wiped off the
body and the rotating hub. We recommend sanitizing wipes or a damp paper towel with an
anti-microbial cleaning solution. DO NOT IMMERSE THE THERMAPEN. The built-in seals will
protect the Thermapen from incidental moisture but due to the folding probe, the Thermapen
should not be submerged. Protect the plastic body from high temperatures. DO NOT LEAVE
THE THERMAPEN IN AN OVEN OR ON A HOT SURFACE.
Error Messages
•‘Lo’ is displayed if measurements are being made below the instrument range.
•‘Hi’ is displayed if measurements are being made above the instrument range.
•‘Err’ is displayed if the probe develops a fault. Call for details.
