1.1.4 Check Sensors
Look into the sensor ports on the cover of the instrument, to determine the number and
type of toxic sensors that are installed.
1.1.5 Check Instrument
The instrument is supplied with a wall plug power supply and a charging base. To
charge the instrument, plug the power supply into the wall and its other connector into
the back of the charging base. Insert the instrument into the base (note instrument
contour and base contour). During the charging process, the alarm LEDs flash
sequentially and a pattern is displayed on the LCD. The instrument is fully charged after
about 4 hours. When the instrument is removed from the charger it performs an auto-
zero which sets gas readings to 0 and oxygen to 20.9%; this must be done in clean air.
