MPO347 M6

4½ digit display in a 48x96 box for Ohm measures (ohmmeter). Optional 4 relays or 8 static alarm outputs and analogue and serial output.

The MPO347 model is a 16 bit A/D converter instrument for resistence measurement.

The option µ26 makes a temperature compensation of the measured value respect the standard 20°C temperature.

The instrument has the following functions:

  • 4½ digit indicator (± 19999)
  • reading of any input value inside the requested range
  • minimum or maximum peak measuring
  • reading at 30 conv/sec
  • "filtering" process for instrument readings
  • zeroing of automatic reading function

The MPO347 M6 instruments can be ordered with the following options:

  • normal or optoisolated bidirectional serial output or monodirectional version for printer.
  • 8 static alarm outputs or 4 relay alarm outputs for normal working or window alarms completely programmable for value, hysteresis and delay
  • normal or optoisolated analogue output (4÷20mA or 0÷20mA or 0÷10V).
  • multi scale by menu selection or serial command.
