Over USB-serial / RS-232. 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 and power supply by its reply and adds it to the bench.
What can I control on the SPM3103?
Multimeter: set mode, range; read meas, mode, overload. Power supply: set current, current limit, output, remote, voltage, voltage limit; read cc, cv, fail, iout, ocp, otp, output, ovp.
Can I log SPM3103 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.
