Control Voltcraft Power Supply and Victor 86C Multimeter
ANNOUNCEMENT
Project has moved to a proprietary website! http://www.instruman.it
Updated source code available at https://instruman.codeplex.com/
This is an interface used to program and control Voltcraft DPPS-32-15 Power Supply, and to log data from Victor 86C Multimeter.
It's an all-in-one solution to use the two instruments at the same time for Scientific, Research and Study purposes.
Features avaible are the following:
-Victor 86C USB HID connection protocol
-86C data reading and logging
-COM port selection
-Continuous reading of Voltage and Current
-Continuous logging of Voltage and Current in a Chart with the option to export data to csv file
-Possibility to set logging rate from 50 ms
-Turn ON and OFF instrument
-Set Voltage and Current
-Set a custom voltage loop to play and reiterate
-Reiteration possible in three ways: for a fixed time, for a fixed number of cycles and until the STOP button is pressed
