QCodes

To connect to a Keysight 34401A Multimeter using Qcodes, you can use the following Python script:

from qcodes.instrument_drivers.Keysight.Keysight_344XXA import Keysight_344XXA

# Create an instance of the Keysight_344XXA driver
multimeter = Keysight_344XXA('multimeter', 'TCPIP0::192.168.1.1::INSTR')

# Connect to the multimeter
multimeter.connect()

# Perform measurements or set parameters using the multimeter object

# Disconnect from the multimeter
multimeter.disconnect()

Note: Replace 'TCPIP0::192.168.1.1::INSTR' with the actual VISA resource name or address of your multimeter.
