Special Note
-1-
When the PGM-50 Multi-gas Monitor is taken out from
the transport case and turned on for the first time, there
may be some residual organic or inorganic vapor
trapped inside the detector chamber. The initial PID or
toxic sensor reading may indicate a few ppm. Ensure an
area free of organic or toxic vapor and turn on the
monitor. After running for several minutes, the residual
vapor in the detector chamber will be cleared and the
reading should return to zero.

The battery of the MultiRAE PLUS monitor will
discharge slowly even if it is turned off. If the monitor
has not been charged for 5-7 days, the battery voltage
will be low. Therefore, it is a good practice to always
charge the monitor before using it. It is also
recommended to fully charge the monitor for AT LEAST
10 HOURS before initial use (see Section 7 for more
information on battery charging and replacement).
