ThermoWorks CF-IR CLOSE FOCUS INFRARED THERMOMETER - Manual (Page 2)

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.
