Specification: Machine type:IR 988 Display range:34.8℃~2.5℃ TEMP resolution：0.1℃/℉ Max.allowabl error：Forehead thermoment in the thermomoent diaplay range of 35.0℃~2.0℃，the maximum allowable error is ±0.2℃ Measuring distance：3cm~5cm Memory array:32 units Clinical repeatability:±0.3℃ Operating environment:Temperature:16℃~35℃；relitave humidity:≤80% Atmospher ipressure:50kPa~106kPa Auto standby funcion:20s Power supply:DC.3V(AA*2) Szie:150*96*44mm Weight:123g Measurement methonds :  Method 1 : In standby mode, the display screen of the infrared thermometer dose not have any display.In standby mode,press the measure key and the diaplay screen will be displayed for about 2 seconds.At the same time,the backlight is turned on,buzzer “beep beep”two short sound,the screen shows the last measurement of the temperature, and the infrared temperature measurement enters the temperature measurement mode. Method 2:In the temperature measurement mode,the infrared detector is pointed at the place where the temperature is to be measured,then press the measuring switch,the backlight illuminated,and the infrared temperature begins to measure the target temperature .After about 1 second,the BUZZER seconds out a prompt sound,the result of the measurement is displayed on the display screen;at this point,the measuring switch can be press again to measure the temperature. Note:When the temperature of your forehead is significantly affted by changes in the ambient temperature,measure it behind your earlobe,as shown in figure 9.3.
