1 - Adjustments of the height system. Option 1 of the main menu.
The measurement of height is based on a system of calculation of distance by means of ultrasounds. The main components
of the system are the acoustic transducer (located at the top of the unit) and the electronic measurement circuit, which is
controlled by the Main Board P1PC. This chapter depicts the procedure to adjust the height system.
1.0 - Reset of the height system
During the autotest process, the unit makes an auto-zero of the height system. With this option of the menu, this process
can be made without having to switch the unit off and on again.
When making an auto-zero of the height system, the unit understands that there is nothing on the platform. The value of the
measured signal at this moment is taken as the zero value (0 cm) of the height system. This is why it is so
important to
check that there is nothing on the platform before doing this process
.
