The OCP parameters setting:
The OCP allows the parameters of an Over Current Protection test to be entered.
The OCP test will ramp up the load current in steps to validate the Device Under
Test's (DUT) protection and behavior. A voltage threshold level can be set. If the
Voltage measured during the test is lower than the set Threshold voltage then the
Test will fail and the display will signal OCP ERROR. Similarly a current Threshold
(I STOP) can be set. If the measured Current reaches the I STOP Threshold the
Test will be discontinued and the OCP ERROR message will be displayed.
Pressing the Item key once will cause the button to illuminate. The message
"OCP PRESS START" will be shown across the displays.
Each press of the setting button moves the menu on one step. The Left and right
LCDs show the currently selected test parameter as text. The value is adjusted by
The rotary knob and can be read from the Right display during Setting.
The setting sequence is shown below:
OCP PRESS START
OCP TURBO
OCP ISTAR
OCP ISTEP
OCP ISTOP
OCP VTH
