a. Check your span gas to make sure it is within specifications.
b. Check for leaks downstream from the cell, where oxygen may be
leaking into the system.
If there are no leaks and the span gas is OK, replace the cell. The only
way to avoid all fail messages is to turn unit off and on.
5.3.3 Removing the Micro-Fuel Cell
The Micro-Fuel Cell is located inside the stainless steel cell block
behind the inner door (see Figure 5-1). To remove an existing cell:
1. Remove power to the instrument by disconnecting it from the
power source.
2. Open the inner door by unlatching it and swinging it open on its
hinges.
3. Leave the cell block installed. Place one hand underneath the cell
block, ready to catch the cell holder and Micro-Fuel Cell.
4. Lift up on the stainless steel gate in front of the cell block. This
releases the cell and cell holder from the block. The cell and
holder will fall into your hand.
