For Model with thermocouple socket

The thermometer is a non-contact infrared thermometer. There are many mathematical modes for the Infrared function. Please remember to keep away from children and don’t use it for safety related applications.

Here will show the emissivity data. (The default emissivity is 0.95.)

CAUTION

1. WHEN DEVICE IS IN USE, DO NOT LOOK DIRECTLY INTO THE TWO LASER BEAMS–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.

STORAGE & CLEANING

It 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.

LCD ERROR MESSAGES

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 temperature. ‘Er3’ is displayed when the ambient temperature exceeds 0 o C (32°F) or +50 o C (122°F). The thermometer should be allowed plenty of time (minimum 30 minutes) to stabilize to the working/room temperature.

FUNCTION

「 」

Error 5~9, for all other error messages it is necessary to reset the thermometer. To reset it, wait for auto power 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. display the surface temperature. The Distance:Spot is 50:1. The two laser points are the reference for the target spot size. Please make sure the target area is within the field of view.

BATTERIES

The thermometer incorporates visual low battery indication as follows:

) or Down key ( ○ ) to set the emissivity, then press Mode key

) to confirm it. The emissivity can be changed from 0.10 (10E) to 1 (100E). ‘Battery OK’: measurements

are possible

‘Battery Low’: battery needs to be replaced, measurements are still possible

‘Battery Exhausted’: measurements are not possible

When the ‘Low Battery’ icon indicates the battery is low, the battery should be replaced immediately with AAA, 1.5V batteries. Please note: It is important to turn the instrument off before replacing the battery otherwise the thermometer may malfunction.

Dispose of used battery promptly and keep away from children.
