Calibration
Full set span calibrations should take place annually for the CO
2
sensor and bi-annually for the O
2
sensor. Always set zero before
setting span. If you have not already done so, download the
package setup software from
http://www.felixinstruments.com/support/F-920
on your computer. This package includes the latest firmware
updates, as well as the controller software needed for real time
monitoring and calibration of the F-920. For CO
2
Calibration
standard gases, we suggest 100% CO
2
for the set span
procedure and a verification gas at a lower value, like 20%. For
O
2
Calibration standard gases, we suggest 50% O
2
for the set
span procedure and a verification using ambient air (20.9% O
2
).
