OPERATING INSTRUCTIONS
The 52226 Dual Temp
Thermometer displays infrared
and contact probe temperature
readings at the same time.
• Pressing the SCAN button
enters the Infrared
Thermometer Function
(IRT Mode).
• Pressing the MEAS. button

Thermometer Function
(COT Mode).
IN NON-CONTACT INFRARED THERMOMETER FUNCTION (IRT MODE)
Simply aim the 52226 at the measure target and press the SCAN button to
display the surface temperature. Distance to target ratio is 1:1, therefore the
thermometer should be positioned as close to the target as possible.
MINIMUM or MAXIMUM MODE
The thermometer can be set to display only the minimum or maximum
temperature reading during any
measurement period.
• To set the minimum mode, press the MODE button once.
• To set the maximum mode, press the MODE button twice.
LOCK MODE
The lock mode is particularly useful for hands-free temperature monitoring.
The thermometer will display the temperature for up to 60 minutes before
automatic shut-off, or until the SCAN button is pressed. To utilize the lock
mode, press the SCAN button, press the MODE button three times, then
press the SCAN button for continuous temperature monitoring.
˚F or ˚C MODE
To change the ˚F or ˚C mode, please press SCAN button, then press MODE
button four times, then press SCAN button.
EMISSIVITY
The infrared thermometer is supplied with a default emissivity of 0.95. The
emissivity can be changed from 0.10 (10E) to 1 (100E). Changes should
only be carried out by experienced personnel. For information relating to the
emissivity of specific materials, please contact the nearest retailer.
Note: Non-contact infrared thermometers are not
recommended for use in measuring the temperature of
shiny or polished metals.
To change the emissivity, press the SCAN button, press the MODE button
five times, press SCAN button for each 0.01 (1E) adjustment, then press
MODE button to lock-in setting.
IN CONTACT THERMOMETER FUNCTION (COT MODE)
Touch the temperature probe to the target, press the MEAS. button.
Temperature will display for up to 4 minutes. After 4 minutes the device will
automatically shut off. Pressing the MEAS. button again will interrupt the
scanning and will hold the last temperature.
After measuring high temperatures, the probe may
remain HOT for a while.

NON CONTACT INFRARED SCAN FUNCTION:
HI – when the temperature is higher than 626˚F
(330˚C).
LO – when the temperature is lower than -67˚F
(-55˚C).
CONTACT PROBE SCAN FUNCTION:
HI – when the temperature is higher than 626˚F
(330˚C)
LO – when the temperature is lower than -67˚F
(-55˚C).
Er 2 is displayed when the thermometer is exposed
to rapid changes in the ambient temperature. Er 3
is displayed when the ambient temperature
exceeds 32˚F or 122˚F (0˚C or 50˚C). The
themometer should be allowed a minimum of 30
minutes to stabilize to room temperature of 32˚F to
104˚F (0˚ to 40˚C).
For all other error messages it is necessary to reset
the thermometer. To reset, turn the instrument off,
remove the battery and wait for a minimum of
one minute, reinsert the battery and turn on. If the
error message remains please contact the Service
Department for further assistance.
