5. Cell Voltage Display Function
After the leads are connected to the battery, the Cell Voltage screen appears.
Cell Voltage
Where Volts = 2.xx is the

The cell voltage displayed is the actual voltage of the cell being charged and is accurate to

±
0.01 volt.
In the Cell Voltage mode, the cell voltage sense leads are connected to the cell, but the
current-carrying charger leads are internally disconnected within the PSC by the charge control
relay. Also, the charger supply is automatically adjusted to equal the cell voltage so that, when
the current leads are internally connected within the PSC, there is no initial current flow.
[PwrSply] Power Supply
- This is the only function available from the Cell Voltage mode
screen. This function selects the Power Supply mode described in the next section.
6. Power Supply Mode
You can use the Power Supply mode to float a cell to a level or to equalize a cell to a level by
controlling the voltage level and the length of charge time. To select the Power Supply mode,
press the [PwrSply] key on the Cell Voltage screen. In the Power Supply mode, you can set the
charger output voltage to any value up to 3.00 volts.

Figure 3. Power Supply Mode
The Power Supply mode screen shows two voltages. Vfl = 2.15v is the actual cell voltage as
measured at the test clips. The value with the arrow pointing to it, 2.15, is the target voltage to
which the cell is to be charged.
When the Power Supply mode is first selected, the target voltage is automatically set to equal the
actual cell voltage. Since the cell voltage initially equals the PSC target voltage, the charge
current (Ifl) is zero.
