6 Maintenance and quality guarantee

（1） In the normal conditions, the thermometer need not special maintenance, keep off

dampness please. And clean the lens surface of the thermometer regularly

（using lens paper or soft cloth, wipe carefully and do not hurt the lens）;

（2） When the thermometer is not used, cut off the power and cover the lens saving

in the dry and clean circumstances。

（3） The malfunction causing by quality problem of products，free repair within 12

month after leave the factory。Repair lifetime。

7 Notices

（1） When setup the thermometer，the light axis must be vertical to the object,

otherwise will causing measuring error。

（2） The effective distance of laser aim is no more than0.3m。

（3） The thermometer has good response speed and good sensitivity, when the heat

source （object） is instable， it's normal that the display meter of thermometer will

move up and down follow;

（4） The thermometer needs fixed, avoiding vibration。

Confirming the range of measuring: The range of measuring is one of the

thermometer's most important capability quota, every type of thermometer has each

special range of temperature measuring. Narrower the thermometer's range is, the monitor

temperature output signal resolution is higher, and the reliability is resolved easily. That the

range is too wide will lower the accuracy of temperature measuring.

Size of object: According to the principle of infrared thermometer, it's divided into

homochrome infrared thermometer and bicolor infrared thermometer When using

homochrome infrared thermometer, it's better that the area of object exceed the sight-field

by 50%。 And to the small and moving or vibrant object, bicolor infrared thermometer is the

best choice.
