Tables A-2 through A-4 list the supplemental characteristics of the Agilent MCCD System.
Requirements for the external power bus source are also listed. Characteristics are not warranted but are
descriptions of typical performance determined either by design or by type testing.

To measure output probe resistance accurately there must be 50 mV between the +/− power leads and the +/− sense leads. To
measure sense probe resistance accurately, there must be 100 mV of cell voltage.
