to initiate the measurement process. The results of measuring the
width of strips are shown in the upper left part of the window, thickness
– in the upper
right and temperature
– in the central part.
The width of the tape is the result of direct measurement of the micrometer.
The thickness of the tape - the result of indirect measurements, calculated as
follows:
Thickness=(Tape_sp-Shaft_cl) - (Shaft_sp - Shaft_cl),
where Tape_sp
– the current position of the upper surface of the tape (indicated by the
main micrometers, see P. 5.),
Shaft_cl
– position of the shaft surface (main micrometers) while system calibra-
tion (see P.10.3.),
Shaft_sp
– the current position of the shaft surface (indicated by subsidiary mi-
crometers, see P.5),
Shaft_cl
– position of the shaft surface (subsidiary micrometers) while system
calibration.
To control the current thickness indications from 9 micrometers press the
Dis-
play
button.
When the current indication goes beyond the tolerance, the corresponding
measurement is highlighted in orange (Fig. 10).
The tolerance installation procedure is described in the p.10.4.
If the micrometer is not responding, it is highlighted in red.
The measurement results are stored in SQLite database file named
«keep.db»
at the root of the PDA flash drive, see point.10.5.
