1. SAFETY RULES

  

This  Instrument  is  designed  for  indoor  use  at  temperatures             

between 32°F to 122°F (0°C to 50°C), altitudes up to 6500 ft.  

(2,000 m), and 10% to 90% relative humidity.

  To ensure that the instrument is used safely, follow all safety and 

operating instructions in this manual. If the instrument is not used 

as described in this operation manual, the safety features of this 

device might be impaired.

 

To avoid personal injuries and damage to the instrument use ex-

treme caution when working around hot machine or engine parts, 

like radiators, exhaust manifolds, catalytic converters, etc.

4.3 Measurement Procedures

4.3.1  Temperature Measurement

 Hold the instrument by its handle, point the IR Sensor at the area 

or object to measure, and press the Measurement Trigger.

  While the Measurement Trigger is kept pressed, the instrument 

will  continuously  measure  and  update  the  display  with  the 

temperature of the object pointed at with the IR Sensor. 

 After  the  Measurement  Trigger  is  released  the  instrument  will 

hold  the  last  temperature  reading  for  7  seconds,  then  shut  off 

automatically.

4.3.2 Field of view or measurement target area

 To ensure accurate temperature measurements, make sure 

that the target object is larger than the unit spot size, at the 

measuring distance. 

 The smaller the target, the closer you should be. 

 For maximum accuracy, make sure that the target area is at 

least twice as large as the spot size.
