ThermoWorks Thermapen IR Operating Instructions Manual

Thermapen® IR

Operating Instructions

INSTRUMENT OPERATION – The Thermapen IR is both a non-contact
infrared (IR) and a penetration probe thermometer:

IR MODE (Probe in closed position) – Aim the thermometer at an object
while pressing the Scan button . The target's surface temperature will
be displayed. The symbol will appear in the display and the instrument
will continue to measure while the Scan button is held down. When the Scan
button is released 'HOLD' is displayed and the reading is automatically held
for 30 seconds after which the thermometer will turn off.

PROBE MODE – Unfold the probe and insert the tip into the medium or
substance to be measured. The instrument will take a few seconds to
stabilise. The instrument is turned off by folding the probe until fully located
into the rubber probe retainer. The probe should not be rotated more than
180 degrees as damage will occur. When not in use, it is recommended
to store the probe in the closed position. The probe tip is very sharp and
therefore caution should be taken when using.

MEASUREMENT ZONE/TARGET DISTANCE – The measurement zone is
proportional to the distance the Thermapen IR is away from the target. The
Thermapen IR is equipped with a 5:1 lens. If the target is 5 in. away, the
measurement zone will be 1 in. across.

ROTATIONAL DISPLAY – The display will rotate through 90° steps
depending on the direction the instrument is pointing so that it can be used
at any angle or in either hand, in both modes.

MAX/MIN – In IR mode, when 'HOLD' is displayed, press the Mode button
to show the maximum or minimum values of the readings previously taken.
These values are lost when the instrument goes into sleep mode after 30
seconds, or if the probe is opened. If the Scan button is pressed while
viewing Max/Min values the instrument immediately measures and reverts
back into Hold mode when released. Please note: Max/Min is only available
in IR mode.

INSTRUMENT CONFIGURATION – The Thermapen IR has two settings
menus that are accessed depending on the mode in use. Settings in Probe
Mode apply to both IR and Probe measurements while settings in IR mode
are specific to infrared. While in settings the LCD will be locked to horizontal
rotation.

°C/°F – While in Probe mode press and hold the Mode button for 3 seconds
to enter the Instrument settings menu. The display will show ‘CorF’, press
the Scan button to change between °C and °F. Press the Mode button twice
to save and exit - ‘End’ is displayed.
