Readying the PAS V
1.
Be sure the battery is installed and fully charged, with the flashlight ON. There
should be no blinking red battery light.
2. Inspect the inlet/outlet ports of the PAS V to make sure that they are not clogged.
3. Conduct an air blank:
a. Turn on the flashlight and wait a minimum of 1-2 minutes for initialization process
to complete.
b. Take an air sample by pressing the Sensor Control Button; the green indicator
light comes on
c. Observe the light bar for 15-20 seconds. If only the small green sampling
indicator light comes on, the air blank check is OK.
4. Clear a fuel cell overload (if one or more of the bar-graph indicator
lights comes on during air blank):
a. Turn the flashlight on to activate fuel cell heater (check that the HTR light is on).
This speeds the cell’s response, clearance and recovery time.
b. Turn off the PAS V. This also speeds the recovery of the fuel cell.
