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
Photos
TODO.
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]
