5-6. Constant current source operation
The Electronic load can also be used as a high current constant current source if the
following connection is made. This function can be used as a battery charger or other
application. It can also combine two or more modules as one unit by parallel connection for
higher current operation.

5-7. Zero-Volt loading application
As shown in Fig 5-8, the electronic load can be connected in series with a DC voltage source
which output voltage greater than 5V. so that the device under test that are connected to the
electronic load can be operated down to a Zero- Volt condition, the DC voltage source
provides the minimum 5V operating voltage required by the Electronic load. This application
is suitable for low voltage Battery cell with high discharge current testing.
