Quick Start: local
Operating via the handheld programmer
SITRANS LR250 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. There are two ways to access the wizard:
• locally (see
Quick Start Wizard via the handheld programmer on page 36)
• from a remote location (see
Quick Start Wizard via SIMATIC PDM on page 41,
or
Quick Start Wizard via AMS Device Manager on page 63
For more complex setups see
Appendix E: Application Examples on page 142, and for the
complete range of parameters see
Parameter Reference on page 78.
