Connecting to Keithley 6485 by Keithley in Python

Instrument Card

The 5½-digit Model 6485 Picoammeter combines Keithley’s expertise in sensitive current measurement instrumentation with enhanced speed and a robust design. With eight current measurement ranges and high speed autoranging, this cost effective instrument can measure currents from 2nA to 20mA, taking measurements at speeds up to 1000 readings per second. The Model 6485’s 10fA resolution and superior sensitivity make it well suited for characterising low current phenomena, while its 20mA range lets it measure currents high enough for applications such as measuring 4-20mA sensor loops.

import PyTango

# Create a DeviceProxy for the Keithley 6485 Power Meter
device_proxy = PyTango.DeviceProxy("device_name")

# Connect to the device
device_proxy.connect()

# Read the power measurement
power_measurement = device_proxy.read_attribute("attribute_name").value

# Print the power measurement
print(power_measurement)

# Disconnect from the device
device_proxy.disconnect()

In the code above, replace “device_name” with the actual name of the Keithley 6485 Power Meter device in your Tango database. Replace “attribute_name” with the name of the attribute you want to read from the device, such as “Power” or “Voltage”.
