A. Introduction
This infrared thermometer is used for measuring
the temperature of the object's surface, which is
applicable for various hot, hazardous or hard to
reach objects without contact safely and quickly.
This unit consist of Optics, Temperature Sensor
Signal amplifier, Processing circuit and LCD
Display. The Optics collected the infrared energy
emitted by object and focus onto the Sensor. Then
the sensor translates the energy into an electricity
signal. This signal will be turned out to be digital
shown on the LCD after the signal amplifier and
processing circuit.
Functions:
1. Celsius / Fahrenheit switchable
2. Equipped with a laser for aiming
3. Temperature hold
4. LCD backlight
5. 7 seconds auto power off
6. Light weight and easy operation
B. Warning & Cautions
1. Warning:
To avoid the potential situation may cause harm
or damage to people, please pay attention to the
following items:
1) Before you use this unit, check on the plastic
housing carefully. If there is any damage, do not
use it.
2) Do not point laser directly at eye or indirectly off
reflective surfaces.
3) Do not use this unit in the environment of
explosive gas, steam or dusty.

2. Caution:
To avoid the damage of the unit or the target,
please protect from the following situations:
1). EMF (electro-magnetic fields) from arc welders,
induction heaters.
2). Thermal shock (caused by large or abrupt
ambient temperature changes - allow 30 minutes
for unit to stabilize before use.
3). Do not leave the unit on or near objects of high
temperature
C. Distance to Spot size
1. When take measurement, pay attention to the
Distance to Spot Size. As the Distance (D) from
the target surface increases, the spot size (S) of
the area measured by the unit becomes larger.
The Distance to Spot size of the unit is 12:1
***This unit is equipped with a laser, which is used
for aiming.
2. Field of view
Make sure the target is larger than the unit's
spot size. The smaller the target the closer measure
distance. When accuracy is critical, make sure the
target is at least twice as large as the spot size.
