The Voltcraft VC-950 is a 100000/10000 counts, CAT IV (600V) / CAT III (1000V) dual display handheld digital multimeter with Serial/USB connectivity.
It is based on the APPA 505, See also: APPA Multimeters.
The driver supporting these APPA-based devices ("appa-dmm" in sigrok) has been created and will be included in mainline sigrok once it passes acception (see developement repository github.com/Cymaphore/libsigrok branch appa-dmm).
