V. CELL LIFE
The generating cell is consumed during the operation of the unit. Cells
can be purchased for two hours of generation time. Once a cell has been
depleted, it may be replaced with a new cell to provide additional calibration
time. Replacement cells may be stored in their containers in a cool, humid
area for several years under most conditions.
Different types of generating cells can be used with each instrument, both
in the type of gas and in the concentration of the gas being generated. The
microprocessor reads the type of gas and the ppm output of the cell from a
memory chip embedded in the cell body. It then adjusts the current for the
proper gas output. For a complete list of correct cell part numbers, please
refer to the parts list at the end of this manual.
To replace the generating cell in the instrument, press down firmly on the
'cell eject' button at the top of the instrument.. The generating cell plugs
directly up into the cell chamber. Ensure that the pads on the cell board
align with the corresponding pins on the pump board. Care must be taken
when replacing the cell to ensure that the locating pin seats in the alignment
hole of the cell.
Make sure to line up the electrode pins with the corresponding sockets. Do
not force the cell into the cell chamber if it is not properly aligned, otherwise
the pins may become damaged rendering the cell and/or instrument useless.
Note: The generating cells contain very small amounts of acidic
solution and should be disposed of as per local regulations. For more
information, please contact the factory.
