0.00V to the full scale of the Voltage specification. The setting is by rotating
the setting knob.
3.1.19.7 START/STOP Test key.
Press START/STOP key to start or stop the OCP test by OCP test setting
parameter when OCP test function is enabled.
The Load will goes to “ON” automatically when press START/STOP key to
start the OCP test and the Load will goes to “OFF” automatically when
press START/STOP key to stop the OCP test. The Load will stay to “ON” If
load was “ON” before OCP test.
The OCP test function for test the UUT’s over current protection, The OCP
test will start sink current from I-START to increase ISTEP current until the
UUT’s output voltage drop-out lower than the threshold voltage(V-th
setting), and the OCP trip point is between A_Hi and A_Lo limitation, then
lower 5 digits LCD display will shows "PASS", otherwise shows "FAIL".
Press any key to goes to normal mode of LCD display.
3.1.20 START/STOP key
3.1.20.1 Press START/STOP key to start or stop the short test by SHORT

OCP & OPP test function is
enabled.
3.1.20.2 The Load will goes to “ON” automatically when press START/STOP key to
start the short test and the Load will goes to “OFF” automatically when
press START/STOP key to stop the short test. The Load will stay to “ON” If
load was “ON” before short test.
3.1.20.3 The
SHORT

OCP & OPP test will sink load’s full scale current(3311D
60A) until to fit in with the test condition, and the UUT’s drop voltage is
between V_Hi and V_Lo limitation, then lower 5 digits LCD display will
shows "PASS", otherwise shows "FAIL".
Press any key to goes to normal mode of LCD display.

3.1.22 +/- DC INPUT Terminal.
The positive and negative terminal of load input connector, it should connect to the
positive and ground output for a positive output power supply, or the ground and
negative output for a negative output power supply respectively.
Please take care of the voltage and current rating not to excess the maximum
rating of each 33501 series load module. Please check the polarity of DC input
connection also before testing.
3.1.23 V-sense input terminal
To measure the specific voltage points through the V-sense input terminal, refer
Fig 3-3 for detail application information.
