The Voltcraft M-3650CR is a 2000 counts handheld digital multimeter with RS232 connectivity.
It came into the market 1991 and is a rebadged Metex M-3650CR.
The device is not officially supported yet. Experimental support exists since 2013-10-23 using the driver for the Voltcraft M-3650D. Currently the logic test and hFE (Transistor) functions do not work yet.
