F-900 CO
2
PPM Sensor and Battery Power
The CO
2
PPM sensor will draw power when turned on, even if the F-900 is not actively
measuring. If trying to conserve battery life, the sensor should be turned off when not being
used.
Always turn the CO
2
PPM
sensor to “off” for the fastest recharge, either using the mini-
USB cable and computer or with a wall charger.
The CO
2
PPM sensor ranges from 0-2000 ppm. The CO
2
PCT sensor is from 0-20% and
does not have the same power draw.
To turn off/on the CO
2
PPM sensor:
1. Go to Setup>Sensor>Sensor Selection.
2.
When asked “Are you sure you want to continue?” press Enter.
3. Press the down arrow to highlight CO
2
PPM.
4. Press the right arrow key to highlight On/Off.
5. Press the up/down arrow key to toggle On/Off the sensor.
6. Press
Save
when the desired setting is highlighted. This will turn off the CO
2
sensor until
you come back to this menu and turn it back on.
7. If you press Enter, the CO
2
sensor setting will only be temporarily saved. When the
instrument is turned off and then back on, the CO
2
sensor will be enabled.
