9 MEASURING SIZE OF REINFORCEMENT BARS (ORTHOGONAL)

Although the Covermeter includes the AutoSize feature (see page 28), a

separate 'orthogonal' SIZE function is included for accurate measurement of

bar size.

The orthogonal SIZE function is intended to be used to determine the diameter

of a (single) reinforcement bar. Although the associated cover will also be

displayed, this function is not intended to be used for scanning areas.

Orthogonal sizing can be performed at greater depths than the AutoSize

function.

The following sections describe how to use the SIZE function.
