Maintenance
hydroxide, that can be harmful if touched,
swallowed, or inhaled. Avoid contact with any fluid
or powder in or around the unit. What may appear to
be plain water could contain one of these toxic
substances. In case of eye contact, immediately
flush eyes with water for at least 15 minutes. Call
physician. (See appendix, Material Safety Data
Sheet.)
CAUTION:
DO NOT DISTURB THE INTEGRITY OF THE CELL
PACKAGE UNTIL THE CELL IS TO ACTUALLY BE
USED. IF THE CELL PACKAGE IS PUNCTURED AND
AIR IS PERMITTED TO ENTER, THE CELL WILL
REQUIRE AN EXCESSIVELY LONG TIME TO REACH
ZERO AFTER INSTALLATION (1-2 WEEKS!).
5.2.2 When to Replace a Cell
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 3000RS-P is usually characterized inability to
zero the instrument down to a satisfactorily low % reading.
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.
5.2.3 Removing the Micro-Fuel Cell
The Micro-Fuel cell is located inside the cell block behind the front
door (see Figure 2-1). To remove an existing cell:
1. Remove power to the instrument by unplugging the power
cable.
2. Open the front panel door by pulling down the top of the
door. The door is held in place by a magnetic latch.
3. Lift the latch of the cell holder see Figure 5-1.
4. The cell holder and the sensor will drop. See Figure 5-2.
Depending on sensor used, cell adaptor might not be in.
