The
receiver
displays the first test screen, which prompts you
to measure the first cell. Proceed to “Step Seven: Measuring
the Cell and the Strap.”
Operating Note
If there are less than 3 A flowing within the string of cells
selected, the receiver displays a message indicating low
current (Lo_A). This ensures proper current magnitude for
accurate measurement since the total current includes both
current from the BITE 2/2P and any ac ripple current
produced by the battery charger. If significant ripple current
is present and out of phase with the applied source current, a
low current condition may occur. If this happens, first turn off
the BITE 2/2P
transmitter
, then reverse the polarity of the
current source leads
to bring the two currents in phase. For
the majority of applications, this will not present any
difficulty. (Refer to Chapter 5 for more information.)

CAUTION
Do not exceed 25 V dc, the maximum voltage allowed
between the
receiver
and the potential probe.
After the
transmitter
is connected to the battery and is
powered on, the

The digits displayed in the upper left corner of the screen
(001) indicate that you are ready to test the first cell. The
digits in the lower left corner indicate the number of the active
test (for example, T01 for test one, T02 for test two, and so
on).
To begin testing the first cell in the string:
The twisting action of the probe
tips as the handle is pushed
down cleans the point of
contact and provides a better
test connection. See Figure 4-6.

Position the
receiver
on the positive terminal and the
potential probe
on the negative terminal of the cell/jar,
and then press down.
