The Voltcraft ME-42 is a 4000 counts, CAT II (750/1000V) handheld digital multimeter with RS232 connectivity. It is an OEM version of the Metex ME-42. The device was sold by Conrad Elektronik as article 120130 starting from 1999 and is not available any more.

Hardware

Multimeter:

  • TODO
  • Fuses: 800mA/250V 5x20mm and 15A/250V 6x30mm (superfast, ceramic fuses)
  • Battery: 9V NEDA 1604 or 6F22

RS232 cable:

RS-232 cable with DB9 (M) plug.
