The meter features audible alarm to give warnings when CO

2

 concentration exceeds the limit. 

(See P1.0 in setup for setting alarm threshold). It emits beeps(Abt.80dB)when CO

2

 level goes

 

over the set value and stops when any key (but 

) was pressed or readings fall below the 

set value. It beeps again when value goes over the limit. Restart the meter if beeper can't be 
stopped. 
 

AUTO POWER OFF  

 The meter turns off automatically after 20 minutes of inactivity. To override the function, hold 

down 

and 

 for 2 seconds to turn on the meter until 

“n”

 appears. 

NOTE:

 Auto sleep function will be disabled during calibration mode. 

 

SETUP  

Hold down 

 under normal mode for more than 1 sec to enter setup mode. To exit setup, 

press 

 in P1.0 or P3.0 and it returns to normal mode. 

Note:

 P2.0 is not applicable in these models but for future model with 

            CO and CO

 measurement. 

 

  

When entering setup mode, P1.0 and “AL” (Fig.10) are displayed on the LCD. 

 

Press 

to go into P1.1 for setting CO

2

 alarm threshold. The current set value will be blinking 

on LCD (Fig11).  
 

 

 

Press 

to increase the value or 

 to decrease. Each press tunes  

100 ppm and the alarm range is from100 to 9900ppm. When the preferred alarm value is set, 

press 

 to save the setting or 

 without saving and return to P1.0. 

 

 

Press 

or 

 in P1.
