The Gossen Metrawatt Metrahit 28S is a 310000 counts handheld digital multimeter with IR (RS232) connectivity.

Hardware

  • Fuse:
    • FF (UR) 1,6 A/1000 V AC/DC (10 kA) for current 300 mA
    • FF (UR) 10 A/1000 V AC/DC (30 kA) for current 3A, 10A
  • TODO.

Event count mq V, unit V, mqflags AC,RMS,REL Counts events >= 2500 digits that last >=2s with a break >=2s. To activate, switch to voltage ACDC, press yellow button twice. Press up to 4 times to cycle parameters, press long to stop. See manual. Not useful remotely because the current measurement value is sent, not the counter.
Stop Watch (Time data) To activate, select a 3V-1000V range manually, press yellow button, press AUTO for start/stop, DATA for reset. Delivers only invalid data ("Overflow") via IR on  Matthias' test device.
Data Hold mqflags += HOLD Disabled while IR interface is active on  Matthias' test device.
MIN mqflags += MIN Influences only display, via IR flag is set, but actual current value is delivered.
MAX mqflags += MAX Influences only display, via IR flag is set, but actual current value is delivered.

The column "sigrok result" contains in short form what the driver generates for the resp. data type.
