Taking Wall-to-Wall Measurements
Unlike other measuring wheels, the
DigiRoller
™
Plus II
has a built-in
function which enables you to measure true wall-to-wall distances (taking
into account the wheel’s radius when measuring up to a wall). The wheel
radius key will add the radius of the wheel to the measurement.
To measure a room accurately, press the wheel radius key
whenever your measurements begin or end against a wall
(see instructions below).
When you press this key, the
DigiRoller
™
Plus II
will add distance to the
measurement. Depending on your selected wheel size and measurement
units, the first and second presses of this key may not
appear to be adding
equal distances due to display rounding. However, this is a display value
only; internal calculations will be accurate.
