2. Manual
interpretation
This method applies to rebar space smaller than described in table 3.1.
When the field situation is too complex to interpret automatically, you
can determine thickness of cover based on changes of current
thickness and signal value. When this value has 2 or more consecutive
decline then two or more consecutive rise, it can be determined that
there is rebar and the thickness of cover is the minimum value during
the above process. For example, when the current thickness value
changes as follows, there is rebar, 63-62-61-62-63 and the thickness of
cover is 61.

To store the measured thickness of cover
The thickness value automatically tested by instrument can be stored
in group according to object No. It can store up to 992 objects and
every object store up to 999 thickness value of cover. Every number
stores the set default diameter value simultaneously and the default
diameter value is used for measuring the first thickness of cover.
If the amount of storage is more than 0, the default
diameter value can’t be changed.

occasion
1. Dense rebar measurement
Users can select different measurement method based on the tested
objects.

When rebar space of object is large, such as floors, it is better
