This hand-held infrared temperature sensors (hereinafter
referred to as “temperature sensor”) can be used for
measuring temperatures in a non-contact way, which
determines the surface temperature of a test object by
measuring the infrared energy radiated from the surface
of the object. These are high-performance and
high-quality instruments which employ micro computers
for data acquisition and processing.
The instrument have such advantages as large distance
coefficient, broad temperature measuring range, high
precision, and fast response. Boasting multi functions
including emissivity adjusting, maximum temp. reading,
minimum temp. reading, average temp. reading, temp.
difference and upper/lower temp limit setting, over-limit
alarming, etc., the temperature sensors are nevertheless
of small size and light weight, easy to operate, and very
reliable. The devices can be widely used in the industries
of petroleum, chemical engineering, railway, medical
care, power, metallurgy, textile, plastics, metalworking,
energy-saving, etc., where rapid and non-contact
surface-temperature measurements are needed.
1. Product Overview
2. Safety Precautions
WARNING
• Please do not direct laser beam into the eye directly, or
indirectly through reflection.
• Please check the housing of the temperature sensor
before using. Never use a damaged sensor. Check for
any damage or any missing plastic/rubber part.
01
• The battery should be replaced immediately in case the
battery indictor ( ) is shown on display.
• In case the temperature sensor does not function well,
please stop using it. The protecting device of the sensor
may have been damaged. If it appears to have any
problem, please send the sensor for repairing.
• Never use a temperature sensor where there is
explosive gas, vapor or dust nearby.
• Please do not connect the attached probe to a
powered-on circuit.
• In order to avoid being burnt, please be noted that the
measured temperatures for an object with high
reflectivity are lower than its actual temperature.
• In case the temperature sensor is not operated in
accordance with the instructions as stated in this
manual, the protecting function provided for the device
might not function well.
To avoid damaging the temperature sensor or the
equipment to be tested, please protect them from
the following hazards or improper handling:
Attention
• Static charge
• EMF (electromagnetic field) generated by an arc
welder or induction heater, etc.
• Heat impact (Heat impact is caused by large or abrupt
change of the ambient temperature, in which case one
has to wait for 20 minutes to stabilize the sensor before
using).
• Please do not place the sensor on or close to a
high-temperature object.

5. Operation Instructions
5.1 Manual Measurement
To measure temperature, point the temperature sensor
right toward the object, and then pull the trigger to start it.
Please do pay attention to the optical resolution(D:S)
and the observation view. The laser is used only for the
aiming purpose.
Gently touch the MODE key on the panel to switch the
flashing symbol at the lower-left corner of the panel
cyclically in the shown order.
5.2 Degree Celsius/ Fahrenheit Toggling
Gently touch the °C/°F key on the panel to conveniently
toggle between degree Celsius and degree Fahrenheit.
5.3 View Max/Min/ Ave/Diff Temperature
5.4.1 When using K-type probe for measuring
temperature, please do properly insert the K-type
probe into the K-type standard temperature base
at the lower part of the sensor.
5.4.2 Pull the trigger on the sensor, wait for the sensor to
be switched into the measuring mode, and then
gently touch “SEL” key on the sensor for a short
moment. The sensor will then be switched into the
mode of K-type temperature measurement (as
shown in the figure).
Please do not connect the attached probe to a
circuit with power on.
There might be a difference between the measured
values for the same object under the infrared mode
and the probe measurement mode. The reason is
due to the emissivity of the object being tested.
For details, please refer to the emissivity
comparison table.

5.4 Connect the Temperature Probe
5.5.1 Emissivity is a measure of the radiation energy of
the corresponding material. Most organic material
and painted surfaces or oxidized surfaces have an
emissivity of 0.95. The preset emissivity of the
temperature sensor is 0.95. The readings might
not be accurate when measuring shining metal
surfaces. To correct the readings, you can use
opaque photo paper or black paint to cover the test
surface (< 148°C /300°F). Wait until the
temperature of the photo paper or paint is the
same as that of the covered surface. Then,
measure the temperature of the photo paper or the
surface of the paint.

5.5.2 Pull the trigger on the sensor and wait the sensor
to be switched to the measuring mode, and then
gently touch “SEL” key on the sensor twice. The
emissivity symbol “EMS” will be shown on LCD,
together with the value of emissivity E=1.00.
5.5.3 Gently touch the “▲”key on the panel to increase
the emissivity value as shown on display; Press

5.8.3 Repeat the above steps to record again. When a
record position number of “99” is shown, pressing
“MEM” will not activate data recording.
5.8.4 To recall the saved data of an infrared
measurement, you need to pull the trigger. Then,
gently touch “RCL” key, and “RCL”(recall) is shown
at the lower left corner of LCD; Gently touch “▲” or
“▼” to select the position number of the recorded
data, and in the mean time, the saved temperature
values are shown on LCD.
5.8.5 “Record Clear” function allows you quickly clear all
data records saved in the temperature sensor.
This function is effective only when the sensor is
under “RCL”(recall) mode. No matter how many
data records are saved in the sensor, you can use
this “clear” function.
Attention: Use “Record Clear” function only when
all data records saved in the memory of the
temperature sensor are to be deleted.
5.9 AC Power, USB Communication
5.9.1 There are a power socket (DC 9V) and a USB
communication port on the base of the sensor.
The DC 9V power supplier can power the
temperature sensor to perform measurements
for a long period of time. (For your safety, please
use the power supplier provided by our company).
5.9.2 To use the function of USB communication, firstly,
install the communication software from CD, then,
insert the USB data cable to PC and the sensor,
and then pull the trigger. Gently touch “USB” key
on the left side of the sensor so that “ ” symbol
is shown on display; Then, real-time data
transmission can be carried out between the
sensor and PC.
USB
5.8.1 The sensor can save data (up to 100 data positions).
It can also save infrared radiation temperature,
temperature standard (°C or °F) and emissivity.
5.8.2 To save the readings of an infrared measurement,
you need to pull the trigger. In the mean time,
gently touch “MEM” key, and “MEM” (recording) is
shown at the lower left corner of LCD. The Number
for the recorded position is shown at the side of
“MEM”(recording) symbol.
5.8 Save /Recall /Delete A Record 5.8.6 To use “Record Clear” function, you need to
release the trigger under the “RCL”(recall) mode,
and then press “SEL” key for 3 seconds to switch
off the “RCL”(recall) mode. This indicates that
data records have been cleared.

The temperature sensor has an angle of view and a
range of view, as shown in the picture below.
6. Distance To Object Size Ratio (D:S )
Make sure that the test object fully occupies the range
of view of the temperature sensor, i.e., let the sensor
“see” the test object only, without “seeing” any other
object. The larger the object is, the longer the measuring
distance must be; On the contrary, the smaller the object
is, the shorter the distance must be. Measuring distance
to size of the test object ratio (D:S ratio) is 30:1
(MS6540 series) or 50:1 (MS6550 series), as shown in
the graph below:
In order to make sure that the temperature sensor does
not receive infrared radiation from objects other than
the test object, it is advisable to carry out measurements
in a distance shorter than what is calculated according
to D:S.
7. Emissivity
Emissivity is a measure of the radiation energy of the
corresponding material. This temperature sensor allows
you to adjust the emissivity of the sensor according to
the type of the test surface. Please refer to Table 2.
