CALIBRATION AND TESTING

6.1 Introduction

It is necessary to test this product at least every twelve months to ensure that the sensors and

alarms are operational. Periodic testing may be performed simply by using exhaled breath to

generate high CO

and low oxygen alarms on units with an oxygen sensor fitted. Exhaled breath

contains approximately 4% CO

gas to cause alarms on the CellarSafe monitor.

To test the alarms, blow into a plastic bag and hold the open end of the inflated bag tightly over

the sensor(s) until the alarms activate. The CellarSafe display will show increased levels of CO

and decreased levels of oxygen (on units with an oxygen sensor fitted), and the alarms should

activate after approximately 10-15 seconds for oxygen and 25 seconds for CO

Alternatively, Crowcon can provide a calibration unit and calibration gas for checking and

calibrating the sensors. The following sections describe the calibration procedure.
