NOTE:
For convenience, leave the components of the calibration kit connected by the
sample tubing.
Returning to Normal Operation
1.
Remove the voltmeter leads from the amplifier test points.
2.
Secure the junction box cover to the junction box.
3.
When the display reading rises above the decreasing alarm setpoint, return the
controller to normal operation.
NOTE:
If the oxygen reading is below the decreasing alarm setpoint when you return to
normal operation, the controller will initiate the appropriate alarm condition.
4.
Verify that the display reading increases and stabilizes at 20.9% volume.
5.
Store the components of the calibration kit in a safe and convenient place.
