F-900 High resolution CO
2
Sensor and Battery Power
When the High resolution CO
2
sensor is not being actively used, it should be turned off. The CO
2
sensor draws a lot of power; if trying to conserve battery life, the sensor should be turned off when
not being used. The CO
2
sensor will draw power when turned on, even if the F-900 is not actively
measuring. Turn off the CO
2
sensor when charging the unit; otherwise the recharge rate will be
slow.
Always turn the CO
2
sensor to “off” for the fastest recharge, either using the mini-USB cable
and computer or with a wall charger.
To turn off/on the CO
2
sensor:
1.
Go to Setup<Sensor.
2.
Move down to highlight ON or OFF next to CO
2
.
3.
Use the RIGHT arrow key to toggle between ON/OFF.
4.
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.
5.
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.
