1. Product Introduction
Thank you for purchasing this infrared thermometer. The
infrared thermometer is a non-contact infrared
temperature measuring instrument. To measure a
temperature , point the unit at the object until the
temperature is read , pull the measuring trigger and
hold. Make sure the target area is larger than the unit's
spot size. For large target objects assure you are within
target distance.
1-1 Features
Features with board temperature and high DS ratio.
These allow user to monitor the target temperature for a
long distance, far away from the potential risk.
High DS ratio.
Adjustable emissivity from 0.1 to 1.00 in 0.01 steps.
Ultra low power consumption in shutdown mode.
Extended long time measuring reliability.
Laser sighting On/Off is switchable.
Backlit LCD display.
°C or °F selectable.
Electronic trigger lock.
1-2 Applications
Electrical troubleshooting.
Automotive repair and maintenance.
Air conditioner.
Science experiment.
Manufacturing processes of semiconductor technology.
Test terminals on circuits.
Food safety and processing.
Perform HVAC energy audits.

2. Safety Information
Laser Warning Note!
Read the following safety information carefully before
attempting to operate or service the meter. Only qualified
personnel should perform repairs or servicing not covered
in this manual.
EN61326: Electrical equipment for measurement,
control and laboratory use.
IEC61000-4-2: Electrostatic discharge immunity test.
IEC61000-4-3: Radiated ,radio-frequency, electromagnetic
field immunity test.
IEC61000-4-8: Power frequency magnetic field immunity test.
Tests were conducted using a frequency range of 80-1000
M Hz with the instrument in three orientations.The average
o o
error for the three orientations is ±0.5 C (±1.0 F) at 3V/m
throughout the spectrum. However, between 781-1000MHz
at 3V/m, the instrument may not meet its stated accuracy.
Dangerous, refer to this manual before using the meter.
CE Certification.
