The menu DIRP
A touch on the button DIRP from the main menu opens the screen for the automatic resonance
analysis “DIRP“.
“DIRP” stands for: D ual I ntegration R esonance
P rocedure
“DIRP” registers resonances to frequencies
applied in steps of “DELTA F” within the limits
between a lower value “Fmin” and an upper
value “Fmax”.
SINE signals will be automatically assigned for
the analysis.
The analysis is based on two readings:
1. MV = M easured V alue of a resonance
2. CV = C onductivity V alue
The Conductivity Value is a personal constant of the individual analyzed. It should read between 5%
and 25% as a base for useful results of the analysis. The Measured Values are shown as a yellow line
in the graph.
After completing a “DIRP” run, the algorithm calculates the level of a horizontal line (violet) in the
graph, called the
C lipping L evel = CL. It separates as close as possible the 10 highest resonance
peaks (HITS) of the graph from the rest. If required, the CL line can be moved up or down manually.
Please note that the results of a DIRP session are in a temporary memory. If the results shall be used,
the button SAVE must be pressed to assign to the adjusted memory slot and the corresponding
frequencies are then saved in the program of the “123” section. Previously memorized frequency
values are overwritten. SAVE does not affect the “DUO” memory section.
Fmin touch to set “Fmin“
Fmax touch to set “Fmax“
Delta F touch to set “DELTA F“
RECALL touch to recall the results from the temporary memory
SAVE touch to save the DIRP data set back to the active program position. All data
changed versus the recalled set overwrites the old data and also overwrites the
name of the application with the name “DIRP”. This can be easily edited in the
“123” program section.
All details of the recalled analysis, including the settings for “Fmin”, “Fmax”, “DELTA F” and the
Clipping Level “CL” (the horizontal line), will be displayed in the graph. This line sits in the
graph where
touch to move the horizontal line upward, thereby reducing the number of HITS (MVs) to deal
with.
touch to move the horizontal line downward, thereby increasing the number of HITS (MVs) to
deal with.
touch to zoom the graph in steps vertically from 0.0 to 2.0 to improve the reading. The Clipping
level will be recalculated to match the moves. Default setting of zoom is 1.0.
