and ink temperature checks, diesel maintenance, and etc.
INTRODUCTION

2
The infrared thermometer consists of optical system, photo detector,
signal amplifier, signal processing and display output system, and
etc. The optical system collects the infrared radiation energy of the
measured area, then this energy is focused onto the photo detector
and changed into electric signal, which is further converted into
temperature value shown on the display.
HOW THE THERMOMETER WORKS
Warning
To avoid possible personal injury, follow these guidelines:
1. Before using the thermometer, inspect the case. Do not use the
thermometer if it appears damaged. Look for cracks or missing
plastic.
2. When the low battery indicator () appears, replace the battery
immediately.
3. Do not use the thermometer if it operates abnormally. When in
doubt, have the thermometer serviced.
4. Do not operate the thermometer where explosive gas, vapor or
dust is present.
5. To avoid heat injury, please keep in mind that the measurement
result of the object with high emissivity may be lower than the
actual temperature of this object.
SAFETY INFORMATION

Cautions
The thermometer should be protected from the following:
1. Electro magnetic fields ( created by arc welders, induction heaters
and similar items. )
2. Thermal shock ( caused by large or abrupt ambient temperature
changes. Allow 30 minutes for the thermometer to stabilize before
use. )
3. Do not leave the thermometer on or near objects of high
temperature.
3
WAVELENGTH 630nm-670nm
As the distance (D) from the object being measured increases, the
spot size (S) of the area measured by the thermometer becomes
larger. This relationship between distance and spot size is normally
expressed as the distance to spot, or D:S ratio, which is shown in
FIELD OF VIEW
6. Do not point the laser beam toward anyone's eye or allow the
laser beam to strike the eye from a reflective surface.

Note:
Make sure that the object to be measured is larger than the
thermometer's spot size. The smaller the object, the closer you
should be to it.
When accuracy is critical, make sure that the object is at least twice
as large as the spot size.

Each time you pull the trigger to make measurements, the
thermometer records the maximum (MAX), minimum (MIN), the
differential (DIF) between the maximum and the minimum, and
the average (AVG) of all readings taken during this pull. These
data are stored in memory and can be recalled with the MODE
button until you pull the trigger ( > 1 sec ) once more. When you
you pull the trigger ( > 1 sec ) once more, all these data will be
erased from memoryand the thermometer will start new recording.
When you pull the trigger, the reading on the main display will
change with the temperaturer of the target surface, and when you
