Connect to the FJ Series in Python

Read our guide for turning Python scripts into Flojoy nodes.

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.

InstrumentKit

To connect to a FJ Series Power Supply using Instrumentkit, you can use the GlassmanFR class from the provided code. Here’s an example script:

import instrumentkit as ik

# Connect to the power supply
psu = ik.glassman.GlassmanFR.open_serial('/dev/ttyUSB0', 9600)

# Set the output voltage to 100V
psu.voltage = 100

# Turn on the power supply
psu.output = True

# Read the output voltage
voltage = psu.voltage
print(voltage)

This script first imports the instrumentkit module as ik. Then, it creates an instance of the GlassmanFR class by calling the open_serial method and passing the serial port name and baud rate as arguments.

Next, it sets the output voltage of the power supply to 100V by assigning the desired voltage value to the voltage property of the psu object.

After that, it turns on the power supply by assigning True to the output property of the psu object.

Finally, it reads the output voltage by accessing the voltage property of the psu object and prints the result.

Note that you may need to modify the serial port name and baud rate to match your specific setup.
