Measuring Size Of Reinforcement Bars Orthogonal; Before You Start; Procedure - Elcometer 331 SH Operating Instructions Manual

9 MEASURING SIZE OF REINFORCEMENT BARS (ORTHOGONAL)
Although the Covermeter includes the AutoSize feature (see page 26), 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.
