MEASUREMENT PROCEDURE
1. Plug the IR probe plug (Fig.1-9) into the meter input
socket (Fig.1-13).
2. Turn meter on using the POWER switch (Fig.1-6).
3. Choose scale using the °C/°F button(Fig.1-3). The chosen
scale will appear in the lower right of the display.
4. Select the resolution by moving the 1°/0.1° switch
(Fig.1-7). Use “1°” for general use.
5. While holding the IR probe main body (Fig.1-11), point the
tip of the probe (Fig.1-12) at the object being measured.
The meter will display the surface temperature.
• The ideal distance between the probe and the surface
being measured is 10 mm (3/8 inch)
• The size of the object should be at least 2.5 mm (3/32 inch)

6. Data Hold: During measurement, the “HOLD” button (Fig.1-
2) will hold the measure value and the LCD will show “D.H.”
in the upper left of display. Pressing the “HOLD” a second
time will release the data hold function.
7. Data Record: The recording function displays the minimum
and maximum readings. To start, press the “RECORD”
button (Fig.1-4). “REC” will show in the lower left of the
display. With “REC” on:
• Press “RECALL”. “MAX” will show in the display with the
maximum temperature value.
• Press “RECALL” again to change display to show the
minimum value. “MIN” will show in the display.
• To exit record mode, press “RECORD”. Display will revert to
current reading.

EMISSIVITY
All objects emit invisible energy. The amount of energy is
proportional to the object’s temperature and its ability to emit
energy. This ability to emit energy is called emissivity and based
upon the composition of the object and the qualities of the
surface. Emissivity values range from 0.10 for a very reective
object to 1.00 for a at black surface.
The probe of the IR Thermometer senses energy and
calculates the temperature based on the amount of IR energy
it receives and a factory set emissivity value of 0.95, which will
cover 90% of the typical applications. However, if the emissivity
value of the measured material is not 0.95, the emissivity value
should be adjusted.
CALCULATING AND ADJUSTING EMISSIVITY
To match the correct emissivity with the specic value of the
object is important in order to obtain exact temperature. When
the emissivity of the object is unknown, calculating the exact
value can be di󰀩cult and require the use of other devices.
However, there are several easy ways of calculating the
emissivity value. For example:
Use a digital thermometer and a surface probe to measure
the object’s temperature as close as possible. Then, while
measuring the object with the IR probe, adjust the “Emissivity
Adjust VR” (Fig.1-10) with a small at head screwdriver until the
readings match.

• Turning the VR to the left (counter-clockwise) will adjust the
emissivity to 0.10 to 0.94.
• Turn the VR all the way to the right to reset the probe to 0.95.
FACTORS AFFECTING MEASUREMENT
1. Measurement Field/Distance:
• The ideal distance between the probe and the surface being
measured is 10 mm (3/8 inch)
• The size of the object should be at least 2.5 mm (3/32 inch)
2. Positioning: For the most accurate reading, the probe
should be held as perpendicular to the object as possible.
This is especially important when the di󰀨erence between
the ambient temperature and the object temperature are
signicantly di󰀨erent.

3. Disturbance: Objects having low emissivity or objects
having a low temperature yet high emissivity emit little
infrared energy. Measurement of these objects is adversely
e󰀨ected by powerful infrared energy radiated from nearby
objects having high emissivity or high temperature. For
example, when measuring objects in sunlight, erratic
measurements are caused as strong radiated energy from
the sun is reected on the surface of the object which
enters the sensor.
4. Incorrect Emissivity: This can cause incorrect readings.
If you believe that this is happening, adjust the emissivity
(refer to page 7).
5. Coating: If the object surface is covered with frost, ice, or
other material, clean it to expose the true surface.
6. Reectance: If the surface is highly reective, apply
masking tape or apply at black paint, or another means to
atten reectivity.

RS232 SERIAL INTERFACE
This instrument works with the Sper Scientic Intelligent
Software and the RS232 serial connection to output data
directly to your computer. You can also use it with other
software using the RS232 output via 3.5 mm terminal (Fig1-
14). The connector output is a 16 digit data stream which can
be utilized by the user’s specic needs.
A RS232 cable (Sper Scientic 840055) or equivalent is
required to link the meter to the PC serial port. The cable
must have a 3.5 mm jack plug and a 9 pin connector where
the center pin equals Pin 2 and the Ground/Shield equals Pin
5. The 16 digit data stream is displayed in the format:
Each digit indicates the following status:

BATTERY REPLACEMENT
“LBT” will appear in the upper left of the display when the
battery outputs less than 6.5 to 7.5 v. You should replace the
battery as soon as possible. However, measurements made
for several hours will still be within specs after the low battery
indicator appears. As the battery depletes, the readings will
become inaccurate.
1. To replace the battery, remove the “Battery Cover” (Fig.1-
8) on the rear of the instrument by careful prying with a at
head screw driver.
2. Remove the battery and replace it with a new 9v battery.
3. Replace the cover.
