Measuring Functions

Access to measuring functions, from the main menu, is done with the F5
key:
7.3.1

Display Freeze

The display freeze is useful when carrying out measurements of a vibrating
or moving system spread out over time. The display is frozen and the two
values that correspond to the same instant are available on the screen.
It is therefore possible to read them without haste (this is a flying spot pic-
ture of a position).
(F5) Return to main menu.
(F4) Normal display.
(F4) Freeze the display.
7.3.2

Offset Origin

This mode, also called relative display, makes it possible to set the current
point as the origin. The values displayed are therefore given in relation to
this point. This mode is practical to find out the angular distance between
two given positions, without having to adjust the zero point to the center of
the sensor.
However, it is necessary to make sure that you do not go beyond the min.
and max. limits on the cell. You are advised to set the first point near the
center of the sensor.
(F5) Return to main menu.
(F4) Freeze the relative display.
(F4) Relative display.
