The UNI-T UT61D is a 6000 counts, CAT II (600V) / CAT III (300V) handheld digital multimeter with RS232 or USB connectivity.
See UNI-T UT61D/Info for more details (such as lsusb -vvv output) about the device.
Hardware

LCD
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.
