My Voltmeter computer interface is the parallelport and the pyvcp component that I loaded is "my-meter". I like to ask 1. Can this voltmeter be used to measure AC voltage up to 1000VAC 2.Can it also be used to measure DC voltage on another count, If yes. Do I need step-down instrument transformers? Please give me a brief on how to go about it. I have a parallel port. I can actually link the Pyvcptp the parallel port input pins. What is the maximum voltage that the paralel port can handle

I would be glad if someone could also give me a reference document to read on this. Thank you It depends on what is your voltmeter's computer interface. I have seen voltmeters with serial port, GPIB, USB, VME, etc. I have a personal project where I use a webcam pointed at a DVM and an image analysis program that reads out the value from the snapshots. As a side effect, it provides optoisolation :) ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
