The UNI-T UT61B is a 4000 counts, CAT II (600V) / CAT III (300V) handheld digital multimeter with RS232 or USB connectivity.
Hardware
Multimeter:
- Multimeter IC: Fortune Semiconductor FS9922-DMM3 (datasheet)
- Crystal: 4MHz (markings: "3.999")
- Fuses: 0.5A/600V and 10A/600V (HRV fuses)
RS232 cable:
See Device cables#UNI-T_UT-D02.
USB cable:
See Device cables#UNI-T_UT-D04.
to use it with this cable, run:
sigrok-cli --driver uni-t-ut61b:conn=1a86.e008 --continuous -O analog
don't forget to run the suspend.HE2325U.sh script, and enable data transmission on the DMM.
