Measuring A-H in the battery test function
To measure the battery capacity in the battery test function:
Using the front panel:
1. Connect the battery to the instrument.
2. Select the battery test function on the startup screen.
3. Press the
MENU
key.
4. Under Source, select
(Dis)charge
.
5. Set the target voltage next to
V-Set
.
6. Set the end current next to
End condition
.
7. Turn
OUTPUT
on in the front panel to discharge the battery.
The 2281S always absorbs 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.
8. Press the
MENU
key.
9. Under Measure, select
A-H/C
.
10. Set the target voltage next to
V-Full
.
11. Set the maximum charging current next to
Source I-Limit
.
12. Set the end current next to
End condition
.
13. Return to the battery test home screen by pressing
HOME
on the front panel.
14. Select
Measure AH
in soft key area 2.
15. Set the state to
On
. The charging starts and data is saved to internal memory.
You can view the charging process by selecting
Graph
or
Data Sheet
in soft key area 3 when the
charging is in progress.
Using SCPI commands:
Connect the battery to the instrument.
Send the command:
:BATT:TEST:VOLT V1
Set the discharging target voltage to V1.
