4.10 PROCESSING OF THE DATA ON A PC (C.A 1727 ONLY)

TACHOGRAPH software can be used for two-way management of the data contained in the C.A 1727.
It allows the acquisition, processing, and analysis of the measurements made by the C.A 1727
tachometer, and the transfer of results files to the hard disc of a PC. It can be used to translate them into
a format compatible with EXCEL, to allow the end user to perform any desired digital processing of the
results. It allows the transfer and display of the programming parameters of the device.
Digital processing of the results, such as calculation of the mean value, of the integral (position), or of
the derivative (acceleration), and the corresponding display in graph form are included in the
TACHOGRAPH software.
The editing functions available in the graph window are:
- Addition of Min + text1, addition of Max + text2, rename the graph.
The display functions available for each graph are:
- Parameterizing of the scale, of the colours, addition of the grid (reticule), of two cursors, of a key
with display of the delta between the cursors, of the Zoom + and - function.
The parameterizing functions for the start of acquisition are:
- Parameterizing of the RS232 communication interface, of the Scan or rate of reading of the
measurement, of the recording thresholds, of the alarms.
