The Gossen Metrawatt T-Com KMM2002 is a 3100 counts handheld digital multimeter with IR (RS232) connectivity and insulation measurement (100 V). It seems to be an OEM version of the Metrahit 16T especially made for T-Com (Deutsche Telekom). An additional feature seems to be a backlight.

The resolution is one digit higher on the data interface.

Hardware

  • Battery: 9 V IEC 6 LR 61
  • Fuse: None! (not required, no internal amps ranges)
  • TODO.

Measurement functions and ranges

The specifications of the KMM2002 seem not to be available to the public. The following are the specs of the Metrahit 16T which seems to be almost identical.

Measurement function Range Resolution Deviation sigrok result Remarks

Event count Seems not to be present on data output.
Data Hold mqflags += HOLD Disabled while IR interface is active on  Matthias' 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.
