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.
Hardware
Multimeter:
- Fuse: 2A/250V (5x20mm) (for the A jack; the 20A jack is unfused!)
- TODO.
RS232 cable:

RS232 cable:
See Device_cables#Metex_5-pin_RS232_cable.
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.
