- generate the time envelope of the signal from the nearest reflector. The measuring cursor will automatically go to the
peak value of the signal and its value will be displayed in the result panel.
Note: During generation of the envelope false signals can appear within limits of the strobe with amplitude values exceeding
the signal amplitude from the nearest reflector. To delete the false signal, relocate the strobe by means of the keys.
- press the key. A confirmation window will be opened (Figure 18);
If the settings are confirmed, the configuration window of the reference level will be closed, and the value of the maximum
amplitude of the signal will be set in the function of the reference level and will correspond to red level of the strobe.
Note: If values of the “Correc-
tion by standard” and “Correction for
roughness” parameters are other than
zero, then their values will be con-
sidered during calculation of the red
(acceptance) level, and all three levels
will be shied by the correction value.
At high correction values the red level
can go beyond the 50 80 % range of
the screen. If so, exit the SETTINGS-
mode and edit the position of the red
strobe level.
To exit the configuration window
without change of the reference level
value, press the key.
Adjustment of the reference level
at switched off multilevel strobe shall
be performed in the same manner.
