Combo Thermometer

Operating Instructions

The Combo Thermometer is not only a non-contact infrared thermometer but also a conventional penetration
thermometer. Choose the mode required, either the IR mode (infrared) or the TC On (probe). To use the non­contact measurement, simply press the IR button and point the thermometer at the target to display the surface
temperature (in the upper display). To use the probe, press the probe button, unfold and inser t into the object
being measured, wait until the temperature stabilizes and the reading will be displayed in the lower display.
Please note: the Combo Thermometer will only display either the IR or probe reading.

Minimum or Maximum Mode (Infrared only)

To utilize the Combo’s minimum or maximum mode, first turn the instrument on by pressing the Infrared
measurement but ton, then press the mode button once for minimum or twice for maximum function. The MIN or
MAX icon will flash, then press the measurement button to confirm the minimum or maximum mode. The Combo
will display the minimum or maximum reading only.

Lock Mode (Infrared only)

The lock mode is particularly useful for continuous monitoring of temperatures. To utilize the Combo’s lock
mode, first turn the instrument on by pressing the Infrared measurement but ton, then press the mode button
three times for the lock mode function. The LOCK icon will flash, then press the Infrared button to confirm the
lock measurement mode. The Combo will continuously display the temperature for up to 60 minutes or until the
Infrared button is pressed.

°C or °F Mode

To change the Combo from °C to °F or from °F to °C, first turn the instrument on by pressing the Infrared
measurement but ton, then press the mode button four times, the °C or °F icon will flash, press the Infrared
button to change, then press again to confirm the mode.

Emissivity

The Combo is supplied with a default emissivity of 0.95. The emissivity of the Combo can be changed from

0.1 (10E) to 1 (100E). Changes should only be carried out by experienced personnel. To change the Combo’s
emissivit y, first press the Infrared button, then press the mode but ton five times for emissivity function. The 95E
will flash on the LCD screen, then press the Infrared but ton to adjust the emissivity value, press the mode button
again to exit the set up screen. For information relating to the emissivity of specific materials, please contact
ThermoWorks or visit www.thermoworks.com. Note: non-contact infrared thermometers are not recommended
for use in measuring the temperature of shiny or polished metals.

LCD ERROR MESSAGES

The Combo incorporates visual diagnostic messages as
follows:

Hi or Lo is displayed when the temperature being measured
is outside of the range of the instrument, Hi when higher
than +428°F and Lo when lower than -27.4°F.

Er2 is displayed when the Combo is exposed to rapid
changes in the ambient temperature. Er3 is displayed when
the ambient temperature of the Combo exceeds 32°F or
+122°F. In both cases you should allow plenty of time
(minimum 30 minutes) for the Combo to stabilize to the
working/room temperature (32 to +104°F).

For all other error messages it is necessary to reset the Combo. To reset, turn the instrument off, remove
the battery and wait for a minimum of one minute, insert the battery and turn on. If the error message
remains please contact the ThermoWorks Service Department for further assistance.
