Returning to Normal Operation
1. Remove the voltmeter leads from the amplifier test points.
2. Disconnect the calibration cup/splash guard’s flexible tubing from the regulator.
NOTE: Do not disconnect the flexible tubing from the calibration cup/splash guard.
3. Secure the amplifier 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 %LEL.
6. Store the components of the calibration kit in a safe and convenient place.
