b. Slide the plastic window to the left to expose the voltage select printed circuit
card (this card is shown in Figure 2-2). The orientation of this card in the
connector determines the voltage option.
c. If the number printed on the outer edge of the board does not correspond to
the available voltage, pull out the card (the fuse must be removed first), and
turn it (either by rotation or inversion) such that the desired voltage is exposed
on the outside edge of the top board. Reinsert the board and replace the fuse.
If the Analyzer is operated from a power outlet without a safety ground
connection, an appropriate adapter must be used. The ground connection of this
adapter must be securely fastened to an external earth ground for safety and
proper operation. A proper ground connection cannot be overemphasized.
The power cord is shipped as a separate item and must be plugged into the
connector on the rear panel (Figure 2-1). To insert the power cord into the power
socket, push up the plastic window and plug in the female end of the power cord.
The plug type on the male end of the power cord may vary depending on the
country of destination.
The A.C. frequency is checked for 50 or 60 Hz operation during the Self-Test
sequence of the Analyzer that occurs on power up (see Section 5.12 for more
details on this Self-Test).
Cell Connection
The cell lead cable is the group of wires that connects the Analyzer electronics to
the electrodes of the electrochemical cell. One end of this cable plugs into CELL
on the rear panel of the Analyzer (Figure 2-1) and the other end is attached to the
electrodes. This may be a direct connection using the general purpose cable sent
with the Analyzer or one for attachment to a cell stand such as the BAS C3 Cell
Stand.
The general purpose cell cable terminates with alligator clips that attach directly
to the cell electrodes (Figure 2-3). There are 3 electrode leads and 1 grounded
(shielding) lead.
