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.

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

Multimeter:

  • Fuse: 2A/250V (5x20mm) (for the A jack; the 20A jack is unfused!)
  • TODO.

RS232 cable:

Photos

Multimeter:

  • Package

  • Package, open

  • Device, front

  • Device, right side

  • Device, back

  • Device, size

  • Device, display self test on power on.

  • Device with test probes

  • Battery pack opened

  • Device opened

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.
