Returning to Normal Operation
1. Remove the voltmeter leads from the amplifier test points.
2. Unscrew the calibration cup from the detector.
NOTE: For convenience, leave the regulator and calibration cup connected by the
sample tubing.
3. Secure the junction box cover to the junction box.
4. When the controller display reading falls below the alarm setpoints, return the
controller to normal operation.
5. Verify that the controller display reading decreases and stabilizes at 0 %Vol.
6. Store the components of the calibration kit in a safe and convenient place.
