ThermoWorks 814-065 COMBO THERMOMETER INFRARED WITH FOLD OUT PROBE - Manual (Page 2)

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 non-contact 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 insert 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 button, then press the mode button once for minimum or twice for maximum function.
The MIN or MAX icon will flash, then press the Infrared 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 button, then press the
mode button three times for the lock mode function. The LOCK icon will flash, then press the Infrared
measurement button to confirm the lock measurement mode. The Combo will continuously display the
temperature for up to 60 minutes or until the Infrared measurement 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 button, 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 infrared thermometer 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 emissivity, first press the Infrared button, then press the mode button
five times for emissivity function. The 95E will flash on the LCD screen, then press the Infrared button 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.
