Table of Contents Introduction
The IDEAL 61-847 Dual Laser Targeting Infrared Thermometer (IRT) is a non
contact temperature sensing meter. Its dual lasers define the outside edges
of the area whos temperature will be measured. The IRT displays the actual
measurement as well as 4 selectable additional measurements. HI and LO
alarms and emissivity are all user programmable.

Operating Features
Power On
A Single Trigger pull turns the unit on and temperatures are immediately
calculated and the IRT displays the temperature of the surface it is pointed at.
(Between the two laser dots).
Taking a Reading
1. Pull and hold the trigger after aiming at the target. The SCAN icon will be
flashing indicating that the target object temperature is being measured.
The measurement result will be updated on the LCD.
2. Release the trigger, the SCAN icon disappears, and the HOLD icon
appears, indicating that the measurement has been stopped and the last
measured value is held.
Viewing the Last Measured Value
When the unit is off, a short press (less than 0.5s) of the trigger turns the
thermometer on and the last measured temperature before the last shutdown
will be displayed. Toggle to view the MAX/MIN/AVG/DIF values by short
pressing the MODE button.

pressing the button or button. Add or subtract 1 each time by short
press, and add or subtract 10 per second by long press. (see Figure 1)
Low Alarm Limit Setting
In the HOLD interface, short press the SET button twice to enter the low alarm
limit setting interface, and adjust the low alarm limit value by pressing the
button or button. Add or subtract 1 each time by short press, and add or
subtract 10 per second by long press. (see Figure 2)

laser will accurately outline the area you are measuring during temperature
measurement.
NOTE: Please follow the laser precautions when the laser is turned on to
avoid damage to human or animal eyes.
Short press the button on the meter to turn the backlight on and off.
The white backlight will remain illuminated for about 5 minutes before
automatically turning off to conserve battery power. Or turn the lights off by
pressing and holding the button again. A long press >2 seconds will turn the
laser on or off.

Lock Measurement
Description:
• In the lock measurement function setting interface, the lock measurement
time (1 minute to 5 hours) can be set. Refer to Lock Measurement Setting
for details.
• After setting time, the measurement starts after the activation of the lock
function. When the set time is reached, the thermometer will automatically
power off and save the last measured value.
• You can view the measured values by short pressing (less than 0.5s) the
trigger (NOTE: The measured values will be cleared by a long press). This
operation is applicable to processes that require regular monitoring of
temperature. If no timing is needed, leave them blank.
Operation:
1. When the lock measurement function is turned on, short press the trigger
to enable it. The icon will appear on the thermometer screen and the
SCAN icon will flash. The thermometer will continuously measure the
target temperature.
2. Pull the trigger again, the and SCAN icons disappear, and the HOLD
icon appears. The thermometer stops the measurement and holds the last
measured value.

Auto Power Off
In the HOLD mode, if there is no operation for 15 seconds, the thermometer
will automatically power off and save the currently held measurement.
NOTE: During measurement, it is best to ensure that the measured target
diameter is twice the spot size (S) of the thermometer, and then determine the
test distance (D) according to the D:S diagram (refer to D:S part).
For example, if you use the 61-847 to measure the temperature of an object
with a diameter of about 4” (10cm), then according to the above, the spot
size (S) of the thermometer should be about 2” (5cm) for highest accuracy,
and according to the D:S diagram, the measured distance (D) is about 24”
(60 cm).
Emissivity
Emissivity is the term used to describe the efficiency with which a particular
surface emits Infra-Red Radiation IN THE WAVELENGTHS that are detectable
by the sensor in the IR Thermometer. Its sensitivity is in the 8 to 14-micron
wavelength range. To be sure, a hot mass will radiate IR in many different
wavelengths, but the sensing technology employed in this type of instrument
has a narrow bandwidth. Some materials, such as electrical tape, human
skin, certain types of paints are efficient emitters in these Wavelengths.
Others such as aluminum, brass, and gold are inefficient emitters, again, IN
THESE WAVELENGTHS. Heat a bar of gold to 200 degrees and try to read
its temperature and it will appear cold. Cover it in electrical tape, and scan
the tape, and the temperature will be much higher and much more accurate.
Please remember this when making measurements of certain objects. This can
and does greatly affect the accuracy of the readings. This is why you can set
the emissivity value in the meter.

Spot Size to Distance
The measured surface area can represent a cone emanating out from the
sensor. The further the distance to the surface, the larger the area that will
influence temperature measurements. It is important that when it safe to
do so, get as close as possible to the target, using the dual lasers to define
the perimeter of an imaginary circle. This will increase the accuracy of the
displayed temperature. Also, make measurements at 90 degrees to the surface
as angular measurements are less accurate. (Reference diagram below)
Field of View
18 19
Spot Size to Distance Field of View
Make sure that the measured target is larger than the spot size. The smaller
the target, the closer the test distance should be (please refer to D:S for the
spot size at different distances). To obtain the optimum measurement result,
it is recommended that the target being measured is 2 times larger than the
spot size.
