IRT203 Manual-FINALrev-001208 2/12/08 3:36 PM Pag

The thermometer is a non-contact infrared thermometer. Simply aim
the thermometer at the target and press the ‘Scan key’ to display the
surface temperature.

LASER INFORMATION:
(FOR MODELS WITH LASER ONLY)

By partially pressing the ‘Scan key’, the device will begin to measure
the temperature of the target. When the ‘Scan key’ is completely
depressed, the laser will operate.

C

AUTION!

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.

°C OR °F MODE

To change the thermometer from ‘°C’ to ‘°F’ or from ‘°F’ to ‘°C’, firstly
turn the instrument on by pressing the ‘Scan key’, then press the
‘Mode key’ four times, the ‘°C’ or ‘°F’ symbol will flash, press the
‘Scan key’ to change to scale.

MINIMUM OR MAXIMUM MODE

To utilize the thermometer’s minimum or maximum mode, firstly turn
the instrument on by pressing the ‘Scan key’, then press the ‘Mode
key’ once for minimum or twice for maximum function. The ‘MIN’ or
‘MAX’ icon will flash, then press the ‘Scan key’ to confirm the
minimum or maximum mode. The thermometer will display the
minimum or maximum reading only.

LOCK MODE

The lock mode is particularly useful for continuous monitoring of
temperatures.

To utilize the thermometer’s LOCK mode, firstly turn the instrument on
by pressing the ‘Scan key’, then press the ‘Mode key’ three times for
the lock mode function. The lock icon will flash, then press the ‘Scan
key’ to confirm the lock mode. The thermometer will continuously
display the temperature for up to 60 minutes or until the ‘Scan key’ is
pressed again.

EMISSIVITY RANGE

The infrared thermometer is supplied with a default emissivity of 0.95.
The emissivity of the thermometer can be changed from 0.05 (5E) to

1.00 (100E). Changes should only be carried out by experienced
personnel. To change the emissivity firstly turn the instrument on by
pressing the ‘Scan key’, then press the ‘Mode key’ five times for
emissivity function. The 95E will flash on the LCD screen, then press
the ‘Scan key’ to adjust the emissivity value,press the ‘Mode key’
again to exit the set up screen. For information relating to the
emissivity of specific materials, please contact the nearest retailer.

NOTE: non-contact infrared thermometers are not recommended for
use in measuring the temperature of shiny or polished metals.

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 range of the instrument,
‘Hi’ when higher than +250°C (482°F) and ‘Lo’
when lower than –55°C (-67°F).

‘Er2’ is displayed when the thermometer is
exposed to rapid changes in the ambient
temperature. ‘Er3’ is displayed when the ambient
temperature of the thermometer EXCEEDS 0°C
(32°F) OR +50°C (122°F). In both cases you should
allow plenty of time (minimum 30 minutes) for the
thermometer to stabilize to the working/room
temperature.

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.

BATTERIES

The thermometer has two separate batteries. The battery closer to the
side of the laser beam output is for laser operation only. The other
battery is designated for temperature measurements. The
thermometer can still measure temperature properly, even without the
laser battery.

The thermometer incorporates visual low battery indication (for the
lower battery) as follows:

BATTERY REPLACEMENT

When the ‘Low Battery’ icon indicates the battery is low, the battery
should be replaced immediately with a CR2032 lithium cell. The
battery is located under the twist cover at the rear of the
thermometer. Please note: It is important to turn the instrument off
before replacing the battery otherwise the thermometer may
malfunction.

Dispose of used battery properly and keep away from children.

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 it, do not submerge
any part of the thermometer. The thermometer should be stored at
room temperature between -20 to +65°C (-4 to +149°F).
