9.2) VISUALIZATION
MEASURES
The real time pages show at each change of page the name of the value displayed; after 2 seconds
the instrument shows the page with the measure. To see another time the name of page, press Enter
key. To set the pages showed as default page press about 3
seconds the key enter and the message “Default Page” will display
for 2 second. The default page is the page displayed when the user
turn on the instrument and the page displayed after 30 seconds of inactivity of keyboard.
