OPERATING INSTRUCTIONS
1. Information is displayed on the LCD through the following symbols:
A. 12/24 hr indicator
B. Clock
C. SET icon
D. COUNT icon
E. LOCK indicator
F. Selected temperature scale
(˚C or ˚F)
G. Ambient temperature icon
H. Temperature reading
I. MIN/MAX indicators
J. HOLD Indicator
K. SCAN indicator
L. Low battery indicator
2. Remove the protective cover from the sensor end of the thermometer.
3. Press the SCAN button to turn the thermometer on.
4. Hold the thermometer like a pen. Position the infrared sensor 0.7 inches / 18mm from the object to be measured.
5. Press and hold the SCAN button with the index finger. The two lasers will converge into one when the exact distance is
obtained. Be sure the target is located at this focal point. The area measured is 0.1 inches / 2.5mm in diameter.
6. Pressing the SCAN button momentarily will result in a momentary reading. Holding the SCAN button will result in a
continuous reading.
7. The thermometer will automatically power off if left idle for more than 15 seconds. If you have set the CLOCK mode,
the clock and ambient room temperature will continue to display even after 15 seconds.
USING THE STOP WATCH
1. Press the SCAN button to turn the thermometer on.
Press the MODE button six times until the COUNT icon flashes.
2. Press the SCAN button to start or stop the stop watch.
Press the MODE button to reset the stop watch to zero.
OTHER FUNCTIONS
Power on and press the MODE button once for the Minimum (MIN) or twice for
Maximum (MAX) modes. When the MIN or MAX icon flashes, press the SCAN button
to confirm. Hold down the SCAN button, the minimum or maximum reading of
measurement will be continuously updated.
Power on and press the MODE button three times. When the LOCK icon flashes,
press the SCAN button to confirm. This mode is particularly useful for continuous
monitoring of temperatures for up to 60 minutes or until the SCAN button is pressed.
Power on and press the MODE button four times. When the °C icon flashes, press
the SCAN button to change the scale to °F.
Power on and press the MODE button five times. When the default emissivity “95E”
appears, press the SCAN button to modify the emissivity setting. Press MODE button
when complete.

CAUTION
1. Do not look directly into the laser beam. Permanent eye damage may result.
2. Never point the device towards anyone’s eyes.
3. Keep out of reach of all children.
STORAGE & CLEANING
The sensor lens should be kept clean at all times and stored at room temperature. Use only a soft cloth or cotton swab
with mater or medical alcohol when cleaning the lens. Allow the lens to fully dry before using. Clean the thermometer
with a damp cloth. The thermometer should be stored between -4 to 149°F / -20 to 65°C.
Readings may be affected if the thermometer is operated within a radio frequency electromagnetic field strength of
approximately 3 volts per meter, but its performance will not be permanently affected. Under an electromagnetic field of
3V/m from 300 to 350 mHz the maximum error is ±6°C.
LCD ERROR MESSAGES
The thermometer incorporates visual diagnostic messages as follows:
Er2 is displayed when the thermometer is exposed to rapid changes in the ambient temperature.
Er3 is displayed when the ambient temperature exceeds 0°C (32°F) or +50°C (122°F). The thermometer
should be allowed plenty of time (minimum 30 minutes) to stabilize to the working/room temperature.
Er is displayed for all other error messages. Clear the error by resetting the thermometer. To reset, turn the
thermometer off, remove the batteries and wait for a minimum of one minute. Reinsert the batteries and turn
it on. If the error message remains please contact ThermoWorks for further assistance.
Hi or Lo is displayed when the temperature being measured exceeds the measurement range of the
thermometer.
BATTERIES
The thermometer incorporates visual low battery indication as follows:
‘Battery OK’ ‘Battery Low’: battery
needs to be replaced.
‘Battery Exhausted’:
measurements may be
affected.
