The most important features of CMM-10 are:
- Autoranging/manual range selection.
- DATA HOLD function, for holding measured values.
- REL function, which allows you to make measurements relative to a stored reference value.
- Continuity test with acoustic signalling (beeper).
- AUTO-OFF function.
- Display 3,4 digits (5000 max).
