The hedue MR6 is equipped with the unique ' R' key. This makes it easy to measure from wall-to-wall or wall-to-point. Pressing the 'R' key once adds the wheel radius to the measured distance. Pressing twice adds the diameter, which is the same as measuring wall-to-wall. Of course this is shown exactly in the display and can be undone just as easily. As you can see, electronics is used here in the measuring wheel in a meaningful way.
The electronic measuring wheel MR6 has all keys and the display on top in the handle. This allows you an ergonomic operation and an error-free reading. Display illumination, hold button (freeze measured value) and reset button (zero button) round off the simple operation.
