INTRODUCTION:
The BC-8000 Battery Capacity Analyzer and Charger will perform capacity
testing of 12 and 24 olt lead-acid batteries and charge the batteries.
Capacity testing amperage setting resolution is 0.1A for tests in the range
of 0.5A to 15A and resolution of 1A for tests from 15A to 55A. The micro
processor controlled unit uses quartz crystal timing and will accurately
measure the capacity of a fully charged battery with a rating between 0.5
and 55 amp-hours. Amperage selection resolution is 0.1A for a load of
0.5 to 14.9 amps and 1A resolution for 15 to 55 amps. The BC-8000
sa es the date, time, test parameters, and test results. It is equipped with
a USB interface. With the BC Report software the user can retrie e data
from the BC-8000 to create a printable report that includes test settings,
test results, time and date of test, and a battery discharge oltage graph.
The BC-8000 is line powered and easy to operate. The recommended
calibration inter al is 1 year.
Battery charging amperage resolution is 0.01 amp from 0.050 to 2.50
amps and 0.1 amp from 2.6 to 25 amps. The battery charger oltage
range is 3.0V to 36.2V. When operating at 3.0V the maximum amperage
is 2 amps. The AC power input is uni ersal 100V to 240V. The charger
can charge in 1 or 2 steps, maximum run time limit on each step, and
operate in constant oltage or constant current mode.
SCOPE:
This document pro ides instructions on how to perform the annual
calibration for the BC-8000. The calibration is broken down into the
following categories:
Verify timing accuracy
Calibrate Cutoff at 10.00 Volts
Calibrate Cutoff at 20.00 Volts
Calibrate 0.5A, 2.0A, 8.5A, 15A, and 55A calibration points
Calibrate the Seiko clock chip (This is optional. The clock is calibrated
at the factory and requires adjustment if the time keeping accuracy is
unacceptable. The date and time are set to the current PC time by the
BC-8000 report utility e ery time test results are transferred from the
BC-8000 to the report utility)
Calibrate the charger oltages and currents.

lead to the positi e terminal of the power source and the BLACK lead
to the negati e terminal of the 24V power source.
5. Verify unit is OFF. Connect the BC-8000 to the VOLTAGE OUTPUT
CONNECTOR on the CF1 test de ice. It is the connector that has two
#16 AWG smaller wires.
6. Locate the display circuit board located on the inside of the front panel
and REMOVE the plastic jumper shunt across pins 1 & 3. See Figure
