8.1 Post-installation check
Before commissioning the measuring point make sure that all final checks have been
carried out:
• "Post-installation check" checklist→  14
• "Post-connection check" checklist →  17
8.2 Switching on the transmitter
Once you have completed the post-connection checks, switch on the supply voltage. The
transmitter performs a number of internal test functions after power-up. As this procedure
progresses, the following sequence of messages appears on the display:
Step Display
1 "Display" text and firmware version of the display
2 Firm logo
3 Device name with firmware version, hardware version and device revision
4 Displays the sensor configuration (sensor type and type of connection) along with the configured
measuring range
5a Current measured value or
5b Current status message

If the switch-on procedure is not successful, the relevant diagnostic event, depending on the cause,
is displayed. A detailed list of diagnostic events and the corresponding troubleshooting instructions
can be found in the "Diagnostics and troubleshooting" section →  35.
The device operates in normal mode after approx. 7 seconds, including the attached
display. Normal measuring mode commences as soon as the switch-on procedure is
completed. Measured values and status values appear on the display.
If the display is attached when the Bluetooth interface is activated, display
initialization is performed twice and Bluetooth communication is disabled
simultaneously.
8.3 Configuring the measuring device
Wizards
The Guidance menu contains various wizards. Wizards not only query individual
parameters but also guide the user through the configuration and/or verification of entire
sets of parameters with step-by-step instructions, including questions, that are
comprehensible for the user. The "Start" button can be disabled for wizards that require
specific access authorization (keyhole symbol appears on the screen).
