35-3001-01H Hydrogen Sample-Draw Detector • 17

5. Disconnect the sample tubing from the inlet line.

6. Unscrew the regulator from the hydrogen calibration cylinder.

Returning to Normal Operation

1. Wait approximately one minute to allow the hydrogen reading to stabilize.

2. Follow the instructions in the controller’s operator’s manual to exit the calibration mode.

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