(Table 5.2-2)
・
There is a number of measurement items in CTS-02V4.
・
Those three items, [Strength(Area Mode)], [Strength(Point Mode)] and [Reactive Side
Impedance], make it possible to estimate the compressive strength of the concrete.
・
When you want to read out the compressive strength as N/mm
2
directly, select
[Strength(Area Mode)] or [Strength(Point Mode)].
・
When you want to read out the compressive strength as the index value, select [Reactive
Side Impedance].
・
The rest of items is used except for estimation of the compressive strength of the concrete.
[Strength(Point Mode)]
・
After hammering at the same position of the concrete twenty times, the mean score will be
calculated.
・
The mean score will be set automatically within ±20 % range.
・
Among the data measured by hammering twenty times, the data beyond the range, if any,
will be excluded automatically from calculation of the mean score.
・
Since then, the data beyond the range will not be obtained with restrictions.
※
Except for [Strength(Point Mode)], it will not be set the mean score or the range as
described above even if hammering at the same position of the concrete twenty times
and will be calculated the simple mean score.

○
It can be readable as N/mm
2
directly. It is not applied
statistical processing such as the range setting or no
restriction for obtaining the data, even if hammering at
the same position of the concrete twenty times.
Strength
(Point Mode)
○
It can be readable as N/mm
2
directly. When hammering
at the same position of the concrete, the range will be set
with restriction for obtaining the data.
Impedance
×
It can be calculated from the entire waveforms by
impact force. It is not possible to estimate the
compressive strength of the concrete.
