uncontaminated air, for most instruments the display should read 0000 within ten seconds of turn-on. For an oxygen
Spectrum, the display reads near 20.9%.

See Table 1.
1.2.1 Verify
The SPECTRUM is calibrated prior to shipment. However, if there is access to a source of the target 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 the target gas is greater than the alarm set point, 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 target gas is greater than the upper alarm limit. See Table 1 for a list
of alarm set points and upper alarm limits for various target gases.
1.2.3 Remove Gas
Remove the source of the target gas. After the display reads zero or close to it, turn the instrument OFF, by pressing
and holding the
POWER / BACKLIGHT pushbutton for approximately three seconds. The display flashes "OFF" and
then goes blank after the pushbutton is released.

If the instrument doesn't operate as described, contact ENMET customer service personnel immediately.
