Battery test
The battery test function allows you to perform the following measurement functions.
Measurement functions
What the instrument measures
Concurrent (V + I)

ESR
Measure the battery resistance
Voc
Measure the open voltage of the battery
A-H
Measure the battery capacity
To select the function from the front panel:
1. Press the
Menu
key.
2. Under
Measure
, select the measurement function of your choosing.

(on page 5-17).
Select a specific measurement range
For the 2281S, you can set specific measurement ranges or allow the instrument to choose the
ranges automatically (power supply function only).
The measurement range determines the full-scale input for the measurement. The measurement
range also affects the accuracy of the measurements and the maximum signal that can be measured.
Selecting a lower measurement range can increase measurement accuracy, but the measurement
must not exceed the range. If the measurement exceeds the range, an "Overflow" error will occur.
