(Table 5.2-3)
・
The parameters are set up for calculation of the index values.
・
The parameters have been already set up based on the results of the calibration test by the
manufacturer at the time of delivery.
・
Some errors will be observed on the estimated strength of the concrete if parameters are
changed by the user side.
・
The numerical numbers of the parameters are inherent to the hammer used. The
parameters are shown in the enclosed certificate of the calibration test.
・
Please confirm whether the parameters are input correctly before using the instrument.
※
The numerical numbers described in this manual are one of examples. Please note that
the numbers are not the parameters of your instrument.
※
Please note that some errors are observed on the estimated strength of the concrete if
you use the other hammer without changes of the numbers of the parameters.
Table 5.2-3 Explanation of Condition
Items Purpose
Mass of Hammer
The weight of the hammer used should be entered. The
current weight is 380 g.
Sensitivity
Sensitivity of accelerometer equipped in hammer is input. The
numerical numbers are inherent to the accelerometer used.
Calibration
This is a calibrated numerical number from the measured
index value to the strength. This number is determined by the
result of the calibration test.
Power Value
This is a power value for conversion of the strength of the
concrete from mechanical impedance index value. If you
choose the type of the concrete, it will be set up automatically.
Trigger Level
This is a trigger value of the measured one. You can set up
between 0-80 %. If you reduce the numbers, it becomes to
react with a weak impact. In case of the concrete, please set
up over 40 %.
※
The mode and parameters for set-up are used for calculation of the actual index values.
