The Velleman DVM4100 is a 6000 count CAT III (1000V) / CAT IV (600V) handheld digital multimeter with USB connectivity.
See Velleman DVM4100/Info for more details (such as lsusb -v output) about the device.
The Velleman DVM4100 model looks identical to the PeakTech 3415, except for its labels and blue case color. The DVM4100 also has similarities with the V&A VA40B but with a different protocol version. This could suggest that those devices share the Dream Tech International DTM0660 as main IC since it's possible to modify certain protocol characteristics using this IC.
15-byte LCD segments over USB-to-serial (Prolific chip, 2400 baud, 8n1). The DMM IC used in this multimeter is a Dream Tech International DTM0660.
To enable output to the PC on the multimeter you have to keep the REL key pressed while powering on the device. However, it will auto-poweroff (after roughly 1 hour?), even in this mode. To avoid that, press both the REL and the SELECT key during power-up (see manual).
