DS-1 digital thermograph is light and elegant appearance, inside and outside dual test temperature, time function, centigrade and fahrenheit can switch. Shaft design can be as test temperature tool of refrigerator, air-conditioner facilities, it also can test temperature in home,office and different locations.

【Techinique parameters】：
Measurement range：-50℃∽+70℃(-58℉∽+158℉)
Accuracy：±1℃
Resolution rate：>-20℃为0.1℃≤-20℃为1.0℃
Power supply method：AAA battery with 1 section

【Operation instructions】：
1、Slide and fetch the battery cover towards the arrow in the back side of the product, put 1section of AAA battery in it and note do not put it wrong with the direction of positive/negative electrode.

2、The LED will be show full screen in 2secs after you put the battery, then it displays internal temperature is (IN). Continuous press MODE button, LED will continuous display contents among Internal temperture(IN), External temperature(OUT) and Clock display.

3、Under clock display situation, press MIN button lightly can adjust entire minute number, and press HR button can adjust entrire hour numbers.

4、Under turn on situation, press MODE button and keep it 4 seconds, then it will be turn off the power. While under turn off situation press MODE button can turn the power on.

5、If LED screen display contents flash 1ce in every minute, that means lack of electricity of battery, you should change the battery imediatly, or will low down the thermograph's accuracy.

【Noted items】：
1、When the tested temperature over  the test range, LED will display "H" which is in the left first place of the dot.

When the tested temperature below the test range,LED will display "L" which is in the left first place of the dot.

2、If LED display contents continuous flash, that means lack of electricity of battery, you should change it imediatly.

Actual pictures1：

There are two detector heads, One used for test the temperature in automobile, the other (see picture) is external detector head which can test the outside temperature.

2.Due to this machine can test inside and outside temperature of automobile, there are two interfaces displayed temperature on screen(inside and outside the automobile)
