Operating Instructions
INSTRUMENT OPERATION
The instrument is switched on by unfolding the probe until the display shows
the temperature. The unit is turned off by folding the probe back into the
side of the unit. The probe should not be rotated more than 180 degrees as
damage will occur. It is recommended to store the probe, in the closed
position, when not in use.
Apply the tip of the probe to the substance, surface or area to be measured.
The probe should be allowed adequate time to stabilize to the temperature of
the item to be measured.
I NSTRUMENT CONFIGURATION
This instrument has four user-selectable slide switches (switch bank), adjustable with a paperclip, and a single push button ‘Trim Adjust’ which is located under the battery cover.
Switch 1 – Units
Changes the instrument’s display units between (°F) Fahrenheit and (°C)
Celsius. The factory default is °F or switch set farthest 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°
the 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 switches set closest to the batteries.
To disable the auto-off function move the switch to the position farthest 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 eeded 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.thermoworks.com.
INSTRUMENT CLEANING – Clean the instrument regularly with an anti-
microbial probe wipe or spray cleaner on a paper towel to avoid potential
food-borne bacteria growth.
WARNING – IPA and other solvents may cause damage to the case and screen
of this instrument.
BATTERY REPLACEMENT – A battery symbol indicates that the batteries will
need replacing. The instrument continues to measure accurately but we
recommend that the batteries be changed as soon as possible. To replace the
batteries, remove the battery cover using a coin (U.S. quarter works best).
Using firm but even downward pressure, rotate the battery cover to the open
position. Remove the batteries by pulling the battery retaining clip back
while holding the unit upside down. Replace both batteries, positive side up,
replace the cover.
ERROR MESSAGES – ‘Lo’ will be displayed if you are measuring below the
instrument’s range. ‘Hi’ will be displayed if you are measuring above the
instrument’s range. ‘Err’ will be displayed if the probe develops a fault. If
the error message remains, contact ThermoWorks Technical Support at
801-756-7705 or email
techsupport@thermoworks.com.
EMC/RFI – Instrument performance may be affected if operated within a
high-frequency radio field, such as near a mobile phone, or if subjected to an
electrostatic shock.
Recommendations for improving surface temperature measurements (Pro-Surface
Thermapen):
- Surface readings may be affected by airflow, sensor contact with the surface being measured, the surface type, surface inconsistencies, and measuring area cleanliness.
- Make sure that the flat bottom area of the probe tip maintains constant and flat contact with the surface being measured.
- Apply firm pressure. Allow sufficient time for the reading to stabilize.
- Clean the surface before taking measurements.
- Readings may be enhanced with a small amount of cooking oil to establish better thermal contact with the sensing area.
- Surface temperatures may vary along hot surfaces. It is recommended to test in multiple locations.
PRODUCT WARRANTY – This instrument carries a two-year warranty against
defects in either components or workmanship. During this period, products that
prove to be defective will, at the discretion of ThermoWorks, be either
repaired or replaced without charge. This warranty does not apply to probes,
where a six-month period is offered.
