Aside from normal cleaning and checking for leaks at the gas connec-

tions, routine maintenance is limited to replacing Micro-Fuel cells and fuses,

and recalibration.

Self-diagnostic testing of the system and fuse replacement in the Con-

trol Unit are covered in Part I, chapter 5 of this manual. For recalibration, see

Part I, section 4.4 Calibration.

4.2

The characteristics of the Micro-Fuel Cell show an almost constant

output throughout its useful life and then fall off sharply towards zero at the

end. Cell failure in the 3010T is usually characterized inability to zero the

instrument down to a satisfactorily low ppm reading. When this occurs, the

3010TAC system alarm trips, and the VFD displays a failure message.

Before replacing the cell:

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.
