The value indicates the typical accuracy of the depth measurement (deviation
from actual) in mm or, respectively, in inches.
4.3.1 Imagescan and Blockscan: Rebar diameter is known
Please refer to the bar diameter tables in the annex (1.).
4.3.2 Imagescan and Blockscan: Rebar diameter is not known
Please refer to the bar diameter tables in the annex (2.).
4.3.3 Quickscan recording: Rebar diameter is known
Please refer to the bar diameter tables in the annex (3.).
4.3.4 Quickscan detection with depth measurement: Rebar diameter is known
Please refer to the bar diameter tables in the annex (4.).
4.3.5 Quickscan detection
Depth measurement is accurate to within ±10% of the effective depth.
4.3.6 Accuracy of bar diameter measurement
± 1 standard diameter when rebar spacing : depth of cover ≥ 2 : 1. Bar diameter measurement is possible only at
depths of up to 60 mm (2.4").
4.3.7 Reinforcing bar location accuracy
Bar center locating accuracy (all modes): Typically ± 3 mm (0.12") relative to the measured position, when the ratio of
bar spacing : depth of cover is ≥ 1.5:1.
