The UNI-T UT61C is a 6000 counts, CAT II (600V) / CAT III (300V) handheld digital multimeter with RS232 or USB connectivity.
See UNI-T UT61C/Info for more details (such as lsusb -v output) about the device.
Hardware
Multimeter:
- Multimeter IC: Fortune Semiconductor FS9922-DMM4 (datasheet)
- Crystal: 4MHz (actually reads "3999" on the crystal)
- Fuses: 10A/240V and 1A/240V (HRV fuses)
RS232 cable:
See Device cables#UNI-T_UT-D02.
USB cable:
See Device cables#UNI-T_UT-D04.

Protocol
See Multimeter_ICs#Fortune_Semiconductor_FS9922-DMM4 for the DMM IC protocol.
Depending on the cable, additional decoding is needed, though.
TODO: Serial cable vs. the two USB HID based cables.
