4. If necessary, use the zero pot on the amplifier to adjust the reading to 100 mV (±2 mV).
5. Turn the regulator knob clockwise to close the regulator.
6. Remove the regulator from the calibration cylinder.
7. Unscrew the calibration cup from the oxygen detector.
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.
