the battery) in ampere*hours (A*hrs) of the battery is calculated and displayed. To run a battery test,
follow these steps:
Key presses
Display
I-set
, enter current value with
numerical keys, then press
Enter
.
Set the DC Load to constant current mode and set the
current you want to draw from the battery. (You may have
to press the
I-set
key twice to be able to set the current
value.)
Shift
+
Battery
MIN VOLT= 0.10V
This indicates you're being asked for the
voltage level where the battery test will be over.
Enter voltage level and press
Enter
.
When you press Enter, the test will start. The
CC
annunciator will be on.
△
or
▽
Shows the power level and the ampere*hours (A*hrs)
accumulated so far.
When the battery voltage drops below the specified value, the test will turn off and you will see
the
OFF
annunciator.
△
or
▽
Display the total charge delivered by the battery in
ampere*hours (A*hrs).
Shift
+
Battery
Turns battery testing mode off.
NOTE: you must make sure that you press
Shift
+
Battery
at the end of the test. Otherwise, the
instrument will not respond to any key presses except
△
or
▽
.
Transient operation
The transient condition allows switching between two different load values. There are three different
types of transient operation.
Continuous transient operation
In continuous transient operation, the load is continuously switched between two load values. An
example is shown in the following figure:
10A
5A
Continuous Transient Operation
2.0ms
3.0ms
Note that this transient behavior works with any of the operation modes CC, CV, CW, or CR. Here
are the keystrokes used to setup this continuous transient condition:
