Special Notes
-1-
When the UltraRAE 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 sensor reading may
indicate a few ppm. Enter an area known to be free of any
organic 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.
-2-
The battery of the UltraRAE 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 first use. See Section 7 for more
information on battery charging and replacement.
-3-
The instrument default condition for the tube barcode
reader is to be “OFF”. In this condition, once a tube is
selected, the instrument assumes that the same type of tube
will be used until a different tube type is programmed.
CAUTION
If the incorrect tube type is programmed or the Measure
Wait Time is otherwise set too short, it is possible to
underestimate the VOC concentration and thereby cause
overexposure. The automatic barcode reader can be enabled
in the program mode (see Section 4).
