4. MEASURING PROCEDURES
Measuring consideration
a. The meter can plug in the max. 1 probes at the same time.
The thress prones are :
CO2 & Humidity probe .
(It can simultaneously measure two kinds of functions.)
b. Though the meter can plug the above 1 probes, but the
meter Display can show the one probe two kind Function
measurement value at the same time.
c. If the meter already plug the above 1 probes,
when make the SD card to record the data, it
can save the one probes two Function measurement value
along the time information at the same time.
Measuring procedures
1) Plug in the " Plug of probe " ( 3-21 Fig. 1 ) to meter's
" Probe Input Socket " ( 3-13, Fig. 1 )
