6.2.2 Handheld programmer functions
The radar device carries out its level measurement tasks according to settings made via
parameters. The settings can be modified locally via the Local User Interface (LUI) which
consists of an LCD display and a handheld programmer.
A Quick Start Wizard provides an easy step-by-step procedure to configure the device for a
simple application. Access the wizards:
● locally [see Quick Start Wizard via the handheld programmer (Page 59)]
● or from a remote location [see Quick Start Wizard via SIMATIC PDM (Page 72),
or Quick Start Wizard via AMS Device Manager (Page 94)]
For more complex setups see Application Examples (Page 63), and for the complete range
of parameters see Parameter Reference (Page 113).
