Troubleshooting
The thermometer should be stored at room temperature. The sensor lens is the most delicate part of the thermometer.
The lens should be kept clean at all times; care should be taken when cleaning the lens using only a soft cloth or cotton
swab with water or medical alcohol, allowing the lens to fully dry before using the thermometer. Do not submerge any
part of the thermometer.
When the ‘Low Battery’ icon flashes, the battery should be replaced immediately with AAA, 1.5V batteries. Please
note: Turn the instrument off before replacing the battery.
Dispose of used battery promptly and keep away from children.

EMC/RFI: Readings may affected if the unit is operated within the radio frequency electromagnetic field strength of
approximately 3 volts per meter, but the performance of the instrument will not be permanently affected.
*IR accuracy can be affected by the emissivity setting, target spot size and rapid changes in ambient temperature.
The thermometer incorporates visual diagnostic messages as follows:
‘Hi’ or ‘Lo’ is displayed when the temperature being measured is outside of the settings of
HAL and LAL.
‘Er2’ is displayed when the thermometer is exposed to rapid changes in the ambient (working
/ room) temperature. ‘Er3’ is displayed when the ambient temperature exceeds 32°F (0°C)
or 122°F (50°C). The thermometer should always be allowed plenty of time (minimum of 30
minutes) to stabilize to the ambient temperature.
Error 5-9 is displayed for all other error messages; it is necessary to reset the thermometer.
To reset the thermometer, turn it 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
Technical Support at [email protected] for further assistance. ‘Hi’ or ‘Lo’ is
displayed when the temperature being measured is outside of the measurement range.
‘Battery Low’ Replace batteries. Measurements are not affected
