OpenEastTester

Open source desktop software for East Tester LCR meters.

Real-time bidirectional synchronization between the PC application and the instrument.

Why?

The official software works, but it feels outdated and lacks several features that make everyday use more comfortable.

This project started as a personal tool for my ET431, but it has been designed with the idea of supporting other East Tester LCR meters using the same serial protocol.

Features

• Real-time measurements
• Bidirectional synchronization
• Automatic hardware state synchronization
• Serial communication
• Modern desktop interface

Supported devices

Tested

• ET431

Expected to work

• ET44x series

If you own another model, please let me know whether it works.
