Special Note
-1-
When the MiniRAE Plus (PGM-76) Professional PID is
taken out from the transport case and turned on for the
first time, there may be some residual organic vapor
trapped inside the ionization chamber. The reading may
therefore show a few ppm. Connect the zero gas adapter
supplied with the unit will clear the residual vapor and
reduce the reading to zero quickly.
-2-
The battery of the MiniRAE Plus unit drains slowly even
when turned off. If the unit has not been charged for 4-5
days, the battery voltage will be low. Therefore, it is a
good practice to leave the unit in the charger so that it is
fully charged and ready for immediate use. It is also
recommended to fully charge the unit FOR AT LEAST
24 HOURS before using it. If the unit is going to be put
on the shelf for more than 4-5 days, it is highly
recommended to turn off the battery switch at the back of
the unit. This will prevent the battery from being deeply
discharged.
