2. With span gas flowing, read the raw output of the cell from the
System
function display.
3. Divide the raw output reading by the percent oxygen
concentration of your span gas.
If the quotient is less than the Index value for the cell class you are
using, replace the cell.

5.2.3 Removing the Micro-Fuel Cell
WARNING: DO NOT TOUCH THE SENSING SURFACE OF THE
CELL. IT IS COVERED WITH A DELICATE TEFLON
MEMBRANE THAT CAN LEAK CAUSTIC AND COR-
ROSIVE CHEMICALS WHEN PUNCTURED.
The Micro-Fuel cell is located inside the housing in a nylon cell
block. (Some models may have a stainless steel block). See Figure 5-2.
To remove an existing cell:
1. Remove power to the instrument by unplugging the power cord
at the power source.
2. Rotate the housing cover counterclockwise until it is free from
the housing, and then remove it.
3. Pull up on the Probe, with a slight rocking motion, to release it
from the Probe Receptacle.
4. Do Not remove the O-rings unless they are worn and no longer
hold the Probe tightly. (If worn, replace them.)
