SOLUTION

5. Under the stable atmospheric environment, the sudden fluctuation of air humidity would have strong 
    impact to accumulative rise and abrupt rise of PM concentration. 
    The strong fluctuation in RH is an essential condition for 32 times higher of abrupt rise in PM 
    concentration so the probability of abrupt rise in PM2.5 concentration is as high as more than 80% 
    due to the aftereffect of strong RH fluctuation
    Please note, extremely high (ex: 85%) or low RH (35%) could not have big effect on the change in PM 
    concentration but the fluctuation of RH can . This explains why the PM2.5 value abrupt rise while the 
    wheather is suddenly changed. 

 

? Unexpected or expected blackout

   While meter is programmed to record data, once the logging is started, blackout will cause the logging function 
   stop. “StoP”  and real time CO

2

 value will appear in turns. 

   Please return to computer to download data and re-program again.  

? NO response at all 

   The meter might crash after long term usage. There are two methods to power on
   again. One, unplug the power cable for 2 hours and then plug again. If you could 
   not wait for 2 hours time to discharge, please use any suitable and available pin 
   to do the hardware reset. The reset hole is on the rear side of meter, next to PM2.5 
   Air In filter.  Using pin to press the reset key and see the display re-start again.

6.While see the need or after replacing filter, you can manually clean up the PM2.5 sensor periodically. 
    Press “

 

SET

” + “         ” keys at the same time to activate the sensor cleaning function for 10 seconds.

    Please do it in clean environment.
