1.2.1 Verify Operation
The S PECTRUM CO RAL is calibrated prior to shipment. However, if there is access to a source of CO gas, such as a
calibration kit, expose the sensor to the gas, and observe that the instrument is responsive.
1.2.2 Acknowledge Alarm
If the concentration of CO is greater than 10 ppm, the instrument indicates an alarm condition. Acknowledge the alarm by
pressing and releasing the right hand pushbutton,
SELECT ; this silences the audio alarm for four minutes unless the
concentration of the CO is greater than the upper alarm limit.
1.2.3 Remove Gas

by pressing and holding the
POWER / BACKLIGHT pushbutton for approximately three seconds. The display flashes "OFF"
