The UNI-T UT60E is a 4000 count CAT III (1000V) / CAT IV (600V) handheld digital multimeter with RS232 or USB connectivity.
It is similar to the Voltcraft VC-840, but not the same device/PCB (and also not just a rebranded device).
Hardware
- Multimeter IC: Fortune Semiconductor FS9721_LP3 (datasheet)
