3350F Series Operation Manual 45
ISTOP: setting the stop current point, The LCD display shows 「OCP」on left 5
digit LCD display, Middle 5 digit LCD display「ISTOP」,right 5 digit LCD display
Setting value, the unit is "A", the setting range is 0.00A to the full scale of the CC
Mode specification. The setting is by rotating the setting knob.
Vth: Setting threshold voltage; The LCD display shows 「OCP」on left 5 digit LCD
display, Middle 5 digit LCD display「Vth」,right 5 digit LCD display setting value, the
Unit is "V", the setting range is 0.00V to the full scale of the Voltage specification. The
Setting is by rotating the setting knob.
Once the test parameters have been entered the test is started by pressing the red
START/STOP button while the OCP PRESS START text is displayed. During the Test
The middle LCD will show run and the actual current being Taken will be displayed
On the lower LCD
Note 1: The message OCP ERROR will be displayed if the DUT fails the test.
The reasons for failure are due to one of the following conditions:
The voltage level of the DUT falls below the set voltage threshold
(OCP Vth) during the test
The current taken from the DUT reaches the OCP I STOP setting.
Note 2: The message PASS will be displayed if the DUTs voltage stays above
The set threshold. Also to PASS the OCP test the current taken from the
DUT cannot equal the I STOP setting.
Note 3: If the DUT passes the OCP test the maximum current taken during the
Test is displayed on the lower LCD.
Upon PASS or OCP ERROR the test will automatically stop. The red
START/STOP button can be used during the test to immediately cease operation.
