The UNI-T UT71C is a 40000/4000 counts, CAT III (1000V) / CAT IV (600V) handheld digital multimeter with RS232 or USB connectivity.
See UNI-T UT71x series for information common to all devices in this series.
Hardware
Multimeter:
- 128 (32 x 4) pattern multi-function LCD driver: HOLTEK HT1621B (datasheet)
- PCB markings: The silkscreen reads "71A(1KV FUSE) V20051010-10", but the correct "C" model indication is apparently added manually by UNI-T using a sharpie.
