A Greater Measure of Confidence
A Tektronix Company
Measuring a battery during charging/discharging process
In the 2281S battery test function, you can conduct a charging/discharging test on a battery. Charging
current ranges from 0 to 6A, and the maximum discharging current is 1A. During the charging, you
can set the sampling interval for the internal 6½ digits multi-meter to sample the charging current
and voltage continuously. Then the capacity of the battery is integrally computed, also the ESR will be
computed. All the test result are saved in the internal memory
After the test, you can generate a battery model based on the measurement result of a battery
charging process. You can also edit the battery model or even create your own battery model, and
import or export a battery model.
