Special Notes
When the instrument is taken out of 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
instrument. 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 instrument discharges slowly even if it is
turned off. If the instrument has not been charged for 5 to 7
days, the battery voltage will be low. Therefore, it is a good
practice to always charge the instrument before using it. It is
also recommended to fully charge the instrument for at least 10
hours before first use. Refer to this User Guide’s section on
battery charging for more information on battery charging and
replacement.
