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 components of the calibration kit connected by the sample
tubing.

3. Secure the junction box cover to the junction box.

4. When the 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 ppm.

6. Store the components of the calibration kit in a safe and convenient place.
