Help on performing a Voltage Sweep with Keithley6487

[Ibrahim330]

Hello,

Following my struggle to get a Voltage-Current Characteristics of an LED, i have end up with the following vi (VICharacteristicLED.vi).Still I am NOT getting the right Curve.
I have also attached the First VI (Loop2do.vi)that I got from an example and using the 6487 drivers itself, but it is unable to make a voltage sweep.

Please i will be very glad to get help from anyone, in order to use one of those 2 VI to make the voltage sweep and record the data in ascii.


Regards,
