Maintenance
4.1 Routine Maintenance
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.
WARNING: SEE WARNINGS ON THE TITLE PAGE OF THIS
MANUAL.
4.2 When to Replace a Cell
If the 3010P analysis readings begin to drift downward uncharacteristi-
cally, try recalibration. If recalibration raises the readings for a short time
only, suspect the cell, but first check for leaks downstream from the cell
where gases may be leaking into the system.
You can check the output of the cell itself by going to the System
function, selecting More, and pressing Enter . The cell output reading will be
on the second line of the display.
Version Self—Test
Cell Output: ### µA
The “good” cell output range depends on the class of cell your analyzer
is using. The B-1 cell is standard in the 3010PAC, but others can be speci-
fied.
