The Tenma 72-9380A is a 40000/4000 count CAT III (1000V) / CAT IV (600V) handheld digital multimeter with RS232 or USB connectivity.
It is a rebadged UNI-T UT71-E.
See UNI-T UT71x series for information common to all devices in this series.
Hardware
Multimeter:
- LSD0007 (possibly TI MSP430 MCU?)
- TI MSP430FE425 microcontroller
- Cyrustek ES51966 DMM chip
- Holtek HT1621 LCD driver
- PCB markings: The silkscreen reads "71E (1KV FUSE) V20051120-9", but an additional "E" model indication is apparently added manually by UNI-T using a sticker.
