5.4.3 Work with a Default Value
Method 3
The purpose of this approach is to work with a default value with known error tolerances.
From the menu item “Bar diameter” select the default value 16 mm or #5 for the diameter.
Use the chart in section 3.4.3 of the tutorial to understand the errors that can be expect-
ed in the cover readings when the actual rebar diameters differ from the reference value.
You may correct the measured cover with the error value.
5.4.4 Drill an Inspection Hole
Method 4
The purpose of this approach is to accurately determine the rebar diameter through destructive
means.
If neither of the methods 1, 2 and 3 are feasible for whatever reason and you are still in doubt (this
could be the case when rebars are bunched too close together or are too small in diameter), then
drill an inspection hole wide enough to allow the use of a caliper to measure the rebar diameter. Set
this value into the Profoscope and proceed.
5.4.5 Diameter Measurements on Welded Reinforcement Meshes
In most cases a diameter can be measured but the displayed value is far too high and cannot be used.
The only way to determine the diameter is by an inspection hole as described under 5.4.4 above.
