If the cell has been depleted, it should be removed and replaced with

a new generating cell. Please refer to the section on cell life for proper

instructions on replacing the generating cells. If the cell has not been

depleted, there may be a faulty electrical connection between the cell and

the instrument. Remove the cell and inspect the pins protruding from the

pump board and the corresponding pads on the cell board. Remove any

debris and or corrosion that may be present and reinsert the cell ensuring

proper alignment. If either the pins become damaged or non-repairable,

the pump board should be replaced..

The rate of airflow through the instrument is critical for accurate gas

concentrations. The flow should be adjusted to 0.5 LPM (liters per minute)

STP (standard temperature and pressure) of sea level and 20

C. (see

chart in section VI) To trim the flow hold the magnetic screw driver over

the 'flow trim' area of the instrument indicated with a magnet symbol. The

GREEN LEDs will begin flashing at a once per second rate indicating the

relative power to the pump. As you hold the magnet over this area the pump

will continue to increase in speed (The LEDs will ramp up indicating the

relative power) until the magnet is removed. When the magnet is reapplied

to the area, the pump speed will decrease (the LEDs will also ramp down

indicating the relative power) until the magnet is again removed. Each time

the magnet is removed and reapplied the flow will change from increasing to

decreasing. This is how the flow rate of the instrument should be adjusted

to obtain 0.5LPM STP. Once the flow is adjusted the instrument will save

the flow data and return to that flow rate for future use
