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. 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 specification of the KMM2002 seems not to be available to the public. The following are the specs of the Metrahit 16T which seems to be quite identical.
