CAUTION
Identifies conditions and actions that could result in meter damage or an incorrect
reading if the hazard is realized.
• Do not disassemble or modify the thermometer or laser.
• This unit has no serviceable parts.
• To avoid false readings, replace the batteries as soon as the low battery
indicator ( ) appears.
• Do not use without the batteries correctly in place and the battery door
closed and secured.
• Inspect the case before using the thermometer. Do not use the thermometer
if it appears damaged. Look for cracks or missing plastic.
• Using the thermometer around steam, dust, or environments with large
temperature fluctuations may lead to inaccurate temperature measurement.
• To ensure measurement accuracy, please place the thermometer in the
measurement environment for 30 minutes before using.
• Avoid keeping the thermometer near high temperature environment for
long periods.
• Clean the case and accessories with a damp cloth and mild detergents only.
Do not use abrasives or solvents. Make sure the meter is completely dry
before use.

Operating Features
Measured Surface Outline
A single press of the trigger results in a single area temperature of the surface
whose center is defined by the laser dot.
Scanning
Pressing the trigger quickly places the unit in scan mode which constantly
updates the temperature reading in the display as you aim at different targets.
To remain in scan mode, keep the trigger pressed.
Meter Operation
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.
Centered around the laser dot.
Taking a Reading
1. Pull and hold the trigger after aiming at the target. The measurement result
will be displayed in the LCD.
2. Release the trigger, 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.
Temperature Unit Setting
Located underneath the battery door cover is the Fahrenheit and Celsius and
button. With the 61-827 on, select the C or F scale by simply pushing the
button until F or C appears in the screen.
8 9
Backlight/Laser Pointer
Pulling the trigger automatically turns the backlight on for 8 seconds and also
illuminates the laser pointer.
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 61-827 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 20”
(50 cm).
Auto Power Off
If there is no operation for 8 seconds, the thermometer will automatically
power off and save the currently held measurement.

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.

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 single laser to define the
center 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)

LOHI
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.

Maintenance and Service
Equipment Maintenance and Service
Meter Inspection
Do not use if meter appears damaged. Visually inspect the meter to ensure
case is not cracked.
Battery Inspection/Replacement
Inspect the battery compartment monthly for any signs of degradation. Low
battery voltages will cause inaccuracies in readings. Remove the batteries
for storage or if the meter will not be used for longer than one month. Battery
leakage will compromise the safety of the meter and cause irreparable damage
to internal components.
Maintenance and Storage
Switch off and disconnect the meter completely before carrying out any
maintenance. Clean the case with a damp cloth and mild detergent. Do not
use abrasives or solvents. Keep away from liquids and ensure the meter is
completely dry before use.
Service and Replacement Parts
This unit has no serviceable parts.
