Remove measure label from OpenLayers 3 measure

[المشرف العام]

I have implemented the measure example available on the OpenLayers 3 site (http://openlayers.org/en/v3.11.2/examples/measure.html) and I am currently trying to include a clear button that will clear both the drawn area / line and label from the map.

I've found the getSource().clear() option will clear the drawn shape from the map, but I am struggling to work out how I can clear the measurement label?

I have tried the map.removeOverlay() method with 'measureTooltip' but this doesn't work.

How can I also remove this label from the map?

Thanks
