Application Function
The load supports the following three application functions. Press APP to switch
among the three functions.
 OCP test function
 OPP test function
 Battery test function
OCP Test Function
OCP test principle (as shown in Figure 2-28)
When the OCP test starts, after the input voltage reaches Von, the load will delay for
a period, then starts to sink the current, increasing with incrementing steps at a
certain interval. Meanwhile, the load will compare the detected voltage value with
the OCP protection voltage value. If higher than the protection voltage value, the
load proceeds to run and increases with incrementing steps until reaching the
protection voltage.
If OCP occurs to the DUT, judge whether the current under test is within the
maximum and minimum current range. If yes, the load passes the OCP test; if no,
the load fails the test.
If no OCP occurs to the DUT and the set protection time times out, the load
automatically stops sinking. The OCP test fails, and the test ends.

Operation Procedures:
1. Connect the DUT and the channel input terminals of the load
Turn off the instrument, as shown in Figure 2-2, connect the DUT and the
channel input terminals on the front panel of the load.
