Innova Series Operator’s Manual
C
ALIBRATION
For
optimum
efficiency of the monitor, calibrate the Innova
before
each use.
If multiple calibrations over a period of days indicate that only a minimum of
adjustments are required, the frequency of calibration can be changed to
weekly or monthly, depending on how often the monitor is used, and how
demanding the monitoring environment is.
NOTE
At the very least, “challenge” the normal operation of the oxygen (O
2
)
sensor (if applicable) before every use.
Exhale over the inlet of the probe as you watch the display. The O
2
reading should
decrease
. When the O
2
reading decreases to
19.5%
,
the alarm should activate. This confirms normal operation of the O

Verify the proper operation of the flow alarm circuit by holding your finger
over the inlet of the probe for a few seconds. The pump shuts off,
“PUMP

, and
“PRESS

” alternate with the gas readings
display, the spinning icon changes to an

C
ALIBRATION
Calibrate the sensors at least every one to three months. Calibration frequency
depends on the frequency of use and also the environmental conditions in
which you use the Innova.

IRCUITS
Periodically verify that all visual and audible alarms function properly.
WARNING
Verify alarm circuits in a “fresh air” environment (environment
known to be free of combustible and toxic gases and of normal
oxygen content).
To verify the alarm circuits, use a concentration of the proper gas sample that
is greater than the preset warn or alarm levels. Verify that the LEDs illuminate
and the buzzer sounds. Also verify that the display reading in alarm flashes
during the alarm sequence.
