GW Instek GDM8341 software
Remote control and data logging for the GW Instek GDM8341 multimeter, on Windows, Linux and macOS - with the same panel BenchMesh uses for every multimeter.
Status
Very likely. Support for the GW Instek GDM8341 was written from GW Instek’s programming manual and follows the same engine as the bench-tested instruments, but nobody has confirmed it on a real GDM8341 yet. If you own one, connecting it once and reporting the result moves it to Community-confirmed.
Note: No temperature function (manual p.62); USB virtual COM only

Have one on your bench?
Connect it, press Detect, try the controls - then tell us how it went. Every confirmation moves a model from “Awaiting” to “Community-confirmed” for everyone.

- Over USB-serial / RS-232 or USB-TMC. 115200 baud, 8N1. Plug in the USB cable (or a USB-RS-232 adapter); BenchMesh finds the port. Then press Detect in BenchMesh: it identifies the multimeter by its reply and adds it to the bench.
- What can I control on the GDM8341?
- Multimeter: set mode, range, rate, temp scale, temp sensor; read meas, mode, overload, range.
- Can I log GDM8341 measurements to CSV?
- Yes. Right-click any reading to add it to a recording; every instrument on the bench is sampled on one shared timeline and exported as one CSV.
- Is BenchMesh free?
- Yes. BenchMesh is free and open source, for Windows, Linux and macOS, and works offline.
