Innova Series Operator’s Manual
While in normal operation, press any button to illuminate the display screen
back light.
NOTE
If the Comfort Alert is enabled, the Innova will beep and/or blink
every 3 minutes to remind the operator that the unit is turned on and
functioning.This feature can be disabled or enabled by the operator,
see Chapter 4, Alarms, Comfort Alert, for activating/deactivating this
feature.
Changing Combustible Ranges
The
RANGE
button is used to change the range of combustible gas detected.
The available ranges depend on the version of the instrument, see Chapter 1,
Introduction, Table 1-2. When changing to ppm range the reading is displayed
in the bottom row. If toxic sensor(s) are present the combustible ppm reading
will overwrite the toxic readings. If a toxic sensor(s) goes into an alarm
condition, the instrument will auto range back to the next combustible range,
and allow the toxic sensor(s) to be displayed.
To change the combustible gas range, press and release the
RANGE
button.
The unit will beep once and switch to the alternate range (e.g. % LEL to ppm).
See Appendix C, Innova Land Surveyor, for operation of the
RANGE
button
for Land Surveyor models.
If, while operating in the ppm range, the gas concentration exceeds the full
scale range, the Innova will automatically switch to the % LEL (or % VOL if
so configured) range.
Turning Off the Innova
Press and hold the
ON/OFF
button for 3 seconds. A power off message on the
display screen counts down from 3 seconds. The Innova sounds a pulsing
tone, and the backlight automatically turns on during the power off sequence.
To cancel the power off command, release the
ON/OFF
button before the
display screen goes blank.
NOTE
The STEL, TWA, maximum, and minimum (for O
2
) readings are
automatically reset on power down unless the Lunch Break mode is
enabled, see Chapter 4, User Program, Lunch Break Option for more
detail.
