Tonghui TH2822D CLI

Linux CLI for TH2822D configuration, typed LCR readings, continuous capture, meter-side statistics, tolerance comparison, and catalog-backed SCPI access.

Install

Requires Python 3.10+.

python3 -m venv .venv
.venv/bin/pip install -e '.[test]'

If CP210x access is denied, add the user to dialout once and log in again:

sudo usermod -aG dialout "$USER"

Do not run the CLI with sudo.

Quick use

th2822d measure
th2822d configure --primary C --secondary ESR --frequency 100 --voltage 0.3
th2822d monitor --duration 60 --format csv --output capacitor.csv

Use a known --port directly. list, info, and config are only for uncertain selection, identity, or configuration.

Discharge components before connection. Never measure a powered circuit or apply external voltage to the LCR terminals.

Read only what the task needs

• Configuration and readings
• Monitoring and file formats
• Tolerance and recording
• Catalog and front-panel control
• Protocol and firmware behaviour
• Connected evidence
• Windows feature parity
