The Brymen BM829s is a 10000 counts, dual display, CAT IV (1000V), handheld digital multimeter with USB connectivity. See the BU-86x adapter.
See BU-86x (USB HID).
The user manual references a "BU-82x" which may or may not be a typo. The sigrok support was tested with a BU-86x cable.
One outgoing HID report initiates the transmission of another reading (think serial-dmm packet request). The reading is received in three incoming HID reports. The 24 bytes of payload data carry bitmaps for LCD segments. The vendor provides the protocol description in the download area.
