Thermometer Operating Instructions

The thermometer is a non-contact infrared thermometer, and always with Real-Time Maximum (MAX) data. Please remember to keep away from children and don’t use it for safety related applications.

STORAGE & CLEANING

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. The thermometer should be stored at room temperature between –20 to +65°C (-4~149°F).

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 0oC(32°F) or +50oC
			(122°F).
			The thermometer should be allowed plenty of time (minimum 30 minutes) to stabilize to the
「	」		working/room temperature.
			Error 5~9, for all other error messages it is necessary to reset the thermometer. To reset it,
			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.
			‘Hi’ or ’Lo’ is displayed when the temperature being measured is outside of the
「	」「	」measurement range.

BATTERIES

The thermometer incorporates visual low battery indication as follows:

(Default Screen)

1.Simply aim the thermometer at the measure target with Lens (4) and press Meas. key (6) to display the surface temperature.

2.During the measurement, the MAX reading will be displayed beside the icon.

ADD VALUE:

oC or oF	Press Mode key (2) for oC or oF transferred.
Backlight	LCD Backlight: always on.
Laser	ClassII Laser: always enable while measuring.

EMC/RFI

Readings may be affected if the unit is operated within radio frequency electromagnetic field strength of approximately 3 volts per meter, but the performance of the instrument will not be permanently affected.

* Note: Under the electromagnetic field of 3V/m from 350 to 550MHZ, the maximum error is 8°C (14.4°F).

CAUTION

1.WHEN DEVICE IS IN USE, DO NOT LOOK DIRECTLY INTO THE LASER BEAM–PERMANENT EYE DAMAGE MAY RESULT.

2.USE EXTREME CAUTION WHEN OPERATING THE LASER.

3.NEVER POINT THE DEVICE TOWARDS ANYONE’S EYES.

4.KEEP OUT OF REACH OF ALL CHILDREN.
