2. Allow the gas to flow for two minutes, then verify that the reading matches the response
reading (± 2mV) you determined earlier. If necessary, use the span potentiometer on the
amplifier to adjust the reading to match the correct response reading.
3. Unscrew the regulator from the calibration cylinder.
Returning to Normal Operation
1. Remove the voltmeter leads from the amplifier test points.
2. Unscrew the calibration cup from the detector.

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.
