Connecting to Keithley 2000 by Keithley in Python

Instrument Card

The Model 2000 6½-Digit Multimeter is part of Keithley’s family of high performance DMMs. Based on the same high speed, low noise A/D converter technology as the Model 2001 and 2002, the 2000 is a fast, accurate, and highly stable instrument that’s as easy to operate as it is to afford. It combines broad measurement ranges with superior accuracy specifications

Flojoy

PROTOCOLS > SCPI

📄 IDN

Query a device's identity through the universal *IDN? SCPI command.

📄 MEASURE VOLTAGE

Query an instrument's measured output voltage, such as a DMM or power supply.

📄 SCPI WRITE

Write a SCPI command to a connected bench-top instrument and return the result.

PyMeasure

To connect to a Keithley 2000 Multimeter using Pymeasure, you can use the following Python script:

from pymeasure.adapters import VISAAdapter
from pymeasure.instruments.keithley import Keithley2000

# Create a VISA adapter for the instrument
adapter = VISAAdapter("GPIB::1")

# Connect to the Keithley 2000 Multimeter
meter = Keithley2000(adapter)

# Perform measurements or configure the instrument as needed
meter.measure_voltage()
print("Voltage:", meter.voltage)

meter.measure_current()
print("Current:", meter.current)

meter.measure_resistance()
print("Resistance:", meter.resistance)

# Disconnect from the instrument
meter.disconnect()

This script creates a VISAAdapter object to connect to the instrument using the GPIB address “GPIB::1”. Then, a Keithley2000 object is created using the adapter. You can perform measurements or configure the instrument as needed using the provided methods and properties. Finally, the disconnect() method is called to disconnect from the instrument.
