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.
Hardware

Protocol
The protocol is (partially) documented in the manual of the Voltcraft M-3650CR and was determined completely by testing. See Multimeter ICs#Alternative Protocol.
Support in sigrok
The device is supported by the driver for the Voltcraft M-3650D since 2013-10-23.
Currently the logic test and hFE (Transistor) functions do not work yet.
Example
sigrok-cli --driver=voltcraft-m3650d:conn=/dev/tty.usbserial --continuous --loglevel=1 -O analog
The name of the serial port might have to be adopted depending on operating system and serial port.
