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 display reading falls below the alarm setpoints, return the controller to
normal operation.
5.
Verify that the controller display reading decreases and stabilizes at a typical
background CO
2
level. The 0-5,000 ppm and 0-5 %volume detectors will display a
reading in a fresh air environment because they have low ranges. The 0-50 %volume
and 0-100 %volume detectors will not display a reading in fresh air because their
ranges are too large.
6.
Store the components of the calibration kit in a safe and convenient place.
