Operation Steps
1、The trigger is for starting measuring. Be sure to hold the trigger more than 0.5 seconds to have
an accurate data. In measuring status, the backlight is on, the screen shows SCAN icon and
the reading data, the up shows “REF----”. When released, the reading is stored. 15s backlight
off and 1 minute product off if there is no action.
2、In measuring status (hold the trigger), every press the green key to set the reference
temperature date.
3、In ON status (but not measuring), every press the green key to exchange the units ℉and ℃.
4、In ON status (but not measuring), hold the green key for 2s to turn the product off.
5、In measuring status (hold the trigger), the laser is turn on ; Release the trigger, the laser is off.
6、The yellow button controls three ranges of leak differences（±0.5℃，±3.0℃，±5.5℃）and one
off function. When press the left or the right button, the screen arrows will show the indicated
temperature differences or off function. When finish setting the reference temperature and
leak differences range, the green color indicates the temperature within the range; the blue
color indicates the temperature lower than the range with slow buzzer sound; the red color
indicates the temperature higher than the range with quick buzzer sound; In the followed
conditions, the top has no colors: not-measuring status、measuring status without reference
temperature setting、the reference temperature is set but leak differences control is off .
7、One buzzer occurs when trigger on、measuring、pressing green key for exchange the
temperature units、setting reference temperature; Two buzzers occur when turn off the product
yourself or itself.
8、The low battery icon appears when the power is low.
9、When the environment temperature is higher than the product operation temperature, there
will be fast-paced buzzers, at the same time displays ErAH; When the environment
temperature is lower than the product operation temperature, there will be slow-paced buzzers,
at the same time displays ErAL; When the target temperature is higher than the measuring
temperature, there will be fast-paced buzzers, at the same time displays ErOH; when the target
temperature is below the measuring range, there will be slow-paced buzzers, at the same time
displays ErOL.
