The battery under test and the Model 2281S-20-6 can be connected
by two-wire sense connections. However, four-wire sense
connections, as shown in the following figure, is recommended
because it cancels out the wire resistance.
After connecting the battery to the instrument, to test a battery and
generate a battery model using the front panel:
1. Select the battery test function in the startup screen.
2. Press the
MENU
key.
3. Under
Source
, select
(dis)charge
to conduct settings for
discharging the battery to the empty state first.
2281S always absorb current at its maximum capacity, which is
approximately 1 A. This sink current is not programmable. If the
maximum output current of the battery under test is less than 1
A, you should connect a resistor between the instrument and the
battery to prevent the battery from switching into protection
mode or being damaged.
