IV. NON-NORMAL OPERATION

If either the batteries or the generating cell become depleted, or the

generating cell is removed from the CAL-101, the instrument enters a non-

normal operating condition

Under a low battery condition, the RED LEDs will begin to flash. If the low

battery condition occurs during power up, the RED LEDs will flash dimly

for approximately 10 seconds and then the instrument will power down. If

the low battery condition occurs after start up, the instrument will simply

power down. It is recommended to replace depleted batteries with two "AA"

heavy duty Alkaline batteries for maximum operating life.

If the cell becomes depleted either at start or during calibration, the GREEN

LEDs will begin to 'ramp' up and down from max to min until the cell is

removed. No gas generation will occur during this cell depleted indication.

If there is an error in cell communication when inserted all green LED's

will come on constant indicating a cell failure. Remove the cell and wait for

all LED's to turn off then reinsert the cell ensuring proper alignment of the

pins. If the error continues check the pins and corresponding pads on the

cell for corrosion and attempt cleaning.

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
