TW2 Thermometer – Operating Instructions

The thermometer is a non-contact infrared thermometer. Simply aim the

thermometer at the target and press the SCAN button to display the surface

temperature.

Laser Information:

By partially pressing the SCAN button, the device will begin to measure the

temperature of the target. When the SCAN button is completely depressed,

the laser will operate.

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.

°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 button, then press the MODE button four

times, the ‘°C’ or ‘°F’ symbol will ﬂash, press the SCAN button 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 button, then press the MODE button once

for minimum or twice for maximum function. The ‘MIN’ or ‘MAX’ icon will ﬂash,

then press the SCAN button 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 button, then press the MODE button three times for the lock

mode function. The lock icon will ﬂash, then press the SCAN button to conﬁrm

the lock mode. The thermometer will continuously display the temperature for

up to 60 minutes or until the SCAN button 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, turn the instrument on by pressing the SCAN button, then

press the MODE button ﬁve times for emissivity function. ‘95E’ will ﬂash on

the LCD screen, then press the SCAN button to adjust the emissivity value,

press the MODE button again to exit the set up screen. For information

relating to the emissivity of speciﬁc materials, please refer to our website at

www.thermoworks.com.

Note: Non-contact infrared thermometers are not recommended for use in

measuring the temperature of shiny or polished metals.

Usage In Cold Temperatures

Most infrared thermometers, like the TW2, use a lens to focus the infrared

energy on a sensor before converting to a displayed temperature. Temperature

errors can occur when changing ambient conditions abruptly without adequate

equilibration time. When taking low temperature readings in a walk-in cooler it

is recommended to allow at least 20 minutes for the lens to stabilize in the new

ambient temperature before readings are taken.

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

20 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 without the laser battery.

The thermometer incorporates visual low battery indication for the temperature

measurement battery as follows:

‘Battery OK’:

measurements

are possible

‘Battery Low’: battery

needs to be replaced,

measurements

are possible

‘Battery Exhausted’:

measurements are

not possible

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. .
