The OS423-LS is a non-contact infrared thermometer with mathematical modes for the Infrared function.

Circle/Dot

Laser

(Default Screen)

Simply aim the thermometer at the measure target with Lens (_ ) and press Meas. key (_ ) to display the surface temperature. The Distance:Spot is 30:1. Please make sure the target area is within the field of view.

FUNCTION

Press Emissivity key (_ ) for setting the emissivity

Press Emissivity key (_ ), then press Up key (_ ) 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).

Press Mode key (_ ) for scrolling more display function as follows.

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

Press Mode key (_ ) for the Maximum (MAX), Minimum (MIN), Different between MAX and

MIN (DIF) and Average (AVG) modes. During the measurement, the special modes reading will be displayed beside the mode icon.

Press Up key (_ ) or Down key (_ ) key to change the High Alarm (HAL) or Lo Alarm (LAL), then press Meas. key (_ ) to confirm it. For example: When the reading 26.9

o

C < LAL 27

o

C, the Low icon will flash and you will hear a beep sound.

** The thermometer will automatically shut off if left idle for more than 60sec.

ADD VALUE

In MAX, MIN, DIF,

AVG mode:

Press Up key (_ ) for LOCK mode ON/OFF. The lock mode is particularly useful for continuous monitoring of temperatures for up to 60 minutes.

Thermometer Operating Instructions

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.

STORAGE & CLEANING The thermometer should be stored at room temperature between –20 to +65 o

C (-4~149°F).

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.

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.

‘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:

‘Battery OK’: measurements

are possible

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

‘Battery Exhausted’: measurements are not possible
