Simply aim the thermometer at the measure target and
press the MEAS. button to display the surface
temperature.
The Distance : Spot is 50 : 1. The two laser points are
the reference for the target spot. Make sure the target
area is within the field of view.

FUNCTIONS:

Press the MODE button to scroll through the following: E, MAX, MIN, DIF, AVG,
HAL, LAL, PRB

EMISSIVITY:

Press Emissivity button to display emissivity E , followed by the UP and
DOWN button to set the emissivity levels. Continue by pressing the MODE

button to confirm your setting in the memory. The emissivity can be changed
from .10 (10E) to 1 (100E).

Note: Default emissivity setting is .95 which will be applicable to most common
material surfaces. Further emissivity uses can be checked on a published list.

MAX, MIN, DIF or AVG Temperature Measurement:

Press the MODE button to view the desired function. Press and hold the
MEAS. button and start scanning. During the measurement, the special modes

reading will be displayed beside the mode icon.

HAL, LAL:

Alarms can be set on this unit as warnings or notice of certain temperatures.
Simply press the MODE button several times and scroll until you view (HAL),
High Alarm Level and (LAL), Low Alarm Level on your screen. Once on either
function, you can press the UP and DOWN buttons to lower or raise the
desired alarm temperature. Once these numbers are set your unit will sound an
alarm if these parameters are reached or passed.

PRB:

To use your probe or surface temp. wire, simply scroll with the MODE button
until you can view the (PRB) or probe function on your screen. Plugging the
Thermocouple into the Thermocouple Socket will automatically activate your
probe or surface temp. wire. The unit will display the surface temperature in
the lower right corner of the screen. The unit is also capable of measuring with
the infrared while in the (PRB) mode, offering both surface and laser readings
simultaneously.

Note: Surface and laser readings
may differ due to the emissivity!

Note: To see the MIN or MAX data
while in the (PRB) mode, press
and hold the UP or DOWN button.

unless in PRB mode. (In PRB mode, it will shut off if left idle for more than 9
minutes.)

ATTENTION!

• DO NOT LOOK DIRECTLY INTO THE 2 LASER BEAMS, PERMANENT
EYE DAMAGE MAY RESULT.

• USE EXTREME CAUTION WHEN OPERATING THE LASER!

• NEVER POINT THE DEVICE TOWARDS ANYONE'S EYES!

• KEEP OUT OF REACH OF CHILDREN!

STORAGE & CLEANING

The thermometer should be stored at room temperature between

-4º to 149ºF (-20º to 65ºC). 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. Allow the lens to fully dry before using the thermometer. Do
not submerge any part of the thermometer.

LCD ERROR MESSAGES

HI or LO is displayed when the temperature being measured

HI

is outside of the settings of (HAL) High Alarm Level and (LAL)

LOW

Low Alarm Level.

‘Er2’ is displayed when the thermometer is exposed to rapid
changes in the ambient temperature. ‘Er3’ is displayed when

Er2 Er3

the ambient temperature exceeds -32ºF (0ºC) or 122ºF (50ºC).
The temperature 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

Er

and turn it on. If the error message remains please contact the
Service Department for further assistance.

‘Hi’ or ‘Lo’ is displayed when the temperature being measured

Hi Lo

is outside of the measurement range.
