DELETE OF THE MEASURING
EXIT
The list of the valid measures saved in the EEPROM of the appliance is displayed. By pressing the F2 (up)
and F3 (down) keys it is possible to select the values, while through the F1 key two functions are provided: a
single pressure deletes the selected value, while a longer pressure (for about five seconds) resets the
memory contents.
WARNING
The deletion operations are definitive and they cannot be cancelled, implying the
irreversible deletion of the above-mentioned data.
Every single line represents a different stored measure and it is composed by the following data:
•
Progressive: it represents the progressive number of the measure under consideration, some values can be
missing because of the deletion of one or more measures.
•
Tests identification: in order to make the continuous-mode tests more evident, every single test is identified
by a character, which is gradually increased at the starting of any new test;
•
Time to fly: it represents the elapsed time between the ultrasonic signal emission in the TX channel and the
signal reception in the RX channel, properly adjusted in relation to the calibration values.
The F4 key brings back to the main screen.
2.08 DATA COMMUNICATION
