py-DMM6500

Library to communicate easily with a Keithley DMM6500 multimeter via pyvisa

Note1: Be sure to set the multimeter in SCPI communication mode

Example usage:

import pyvisa as visa
from DMM6500 import DMM6500
from DMM6500_SCPI import Function

mm = DMM6500(visa.ResourceManager().open_resource('USB::0x05e6::0x6500::*******::INSTR'))
mm.reset()
mm.function = Function.DC_VOLTAGE
print(mm.measure())

For more examples, see the examples folder.

Requirements

If you want to just generate the SCPI commands in textual form this library has no requirements.

If you want to communicate with your DMM6500 trough pyvisa this library requires:

• pyvisa

If you have no native visa driver installed, you can use these libraries to handle the communication in user space in linux:

• pyvisa-py
• pyusb

For windows, install the ni-visa from National Instruments.

Documentation

All native SCPI commands are generated by DMM6500_SCPI.py. Please refer to this file for a list of all possible commands.

Commands with the prefix set_ are special in the sense that you can command to set them as if you are setting a property on the multimeter object. For example mm.set_range('auto') does the same as mm.range ='auto'

It is possible to set a bunch of settings at the same time from a dictionary. See example2.py

It could be usefull to refer to the Keithley DMM6500 Reference Manual.

Development

TODO

• Handle overflow nicely
• Add more settings
• Test on Windows
• Generate documentation
