WEBTEC HPM Manual page 14

As the function keys are easy to understand and always function
in the same manner, actuating the function keys has not been
included in the example sequences to ensure that the content of
the menus remain central to the descriptions. It is a pre-condition
for replicating the examples that the function keys are used as
described above.
Example: setting the unit (text) and the measurement range (numeri-
cal)
Text input:
to set the units (max. 15 characters)
Numerical input:
to set the measurement range and signal span
