5.5.2 Pull the trigger on the sensor and wait the sensor 
          to be switched to the measuring mode, and then
          gently touch “SEL” key on the sensor twice. The
          emissivity symbol “EMS” will be shown on LCD, 
          together with the value of emissivity E=1.00. 
5.5.3 Gently touch the “

”key on the panel to increase

          the emissivity value as shown on display; Press 
          the “

” key to decrease it. 

5.5.4 After the above setup is complete, press “MODE”
          to confirm the value of emissivity. 
5.5.5 The effective setup range for radiation: “EMS” is 
          between 0.10 and 1.00. 

5.6 Temperature Limit Alarming Function 

5.6.1 Pull the trigger on the sensor, and gently touch 
          “SEL” key on the left panel consecutively for three
          times, and then “HAL” symbol and “1000” are 
          shown on display, and the sensor is switched to 
          the mode for setting the upper limit alarming.
          Gently touch “

”or “

” to adjust the upper 

          temperature limit alarming value.
5.6.2 After the value is set, gently touch “MEM” key on
          the panel to turn on/off the alarming mode. When
          under “alarming on” mode, “ 

” symbol is shown 

          on display.
5.6.3 Pull the trigger on the sensor, and gently touch 
          “SEL” key on the left panel consecutively for four
          times, and then “LAL” symbol and “00” are shown
          on display, and the sensor is switched to the mode
          for setting the lower limit alarming. Gently touch 
          “

”or “

”to adjust the lower temperature limit

          alarming value.

5.6.5 When the sensor detects that the surface 
          temperature of an object is higher or lower than
          the preset alarming value, it will give off “doo-doo”
          alarming sound, in the mean time “HAL” or “LAL” 
          symbol will flash on display.  

Under the attached probe measuring mode, the 
upper/lower limit alarming function is deactivated. 

5.7 Settings For Auto Measurement 

5.7.1 Pull the trigger on the sensor and wait the sensor
          to be switched to measuring mode, and then gently
          touch “ USB ” key on the left side of the sensor for
          a short moment to shown “ 

” symbol on LCD; 

          Then, press “SEL” key for 3 seconds and the 
          “SCAN” symbol on LCD stops flashing. Release 
          the trigger, and the sensor is switched to the mode 
          of auto measuring.
5.7.2 Under the mode of auto measuring, gently touch
          the “USB” key on the left side of the sensor for a 
          short moment, and the mode of auto measuring 
          is switched off.
