The UNI-T UT61E is a 22000 counts, CAT II (600V) / CAT III (300V) handheld digital multimeter with RS232 or USB connectivity.
See UNI-T UT61E/Info for more details (such as lsusb -vvv output) about the device.
Hardware
- Cyrustek ES51922 multimeter chip (ES51922A actually, as per various photos: 1, 2, 3, 4)

Protocol
TODO.
The transmission of the measurement data cannot be disabled, the respective Cyrustek ES51922 pin (111, RS232) is tied to GND (i.e. transmission is always enabled) on this multimeter.[1]
