Current output and LCD display settings

Current output and LCD display settingsCurrent output and LCD display settings When you do the Standard setup page of the LCD display (in Normal mode) automatically uses settings with the same parameters and values as the current output settings (measurement variable, 0% range and 100% range). The first measurement page shows "one value and bar" by default. If you must show one or more measurement values that are different to the transmitted output signal, change the settings in the C6.4 1st Meas. Page and C6.5 2nd Meas. Page menus. For more data, refer to Function description on page 79

Measurement data includes different measurement types (level, distance, volume, ullage volume, mass etc.). Some measurement types will only be available in Normal mode if you entered the correct parameters in Program mode. Normal mode shows abbreviations of measurement types if the measurement page is configured to show more than one measurement value. For a list of the abbreviations used in Normal mode, refer to the table that follows:

Multiple reflections will cause the device to display smaller level readings. Installation of the device on a manhole or at the centre of a dome roof, and high dielectric products (εr >5) can cause multiple reflections. A very calm surface or a tank with a small convex or flat roof can also cause multiple reflections.

If this function is in operation, the device looks for the first signal peak below the process connection. This signal peak is then used to measure the level of the tank contents. If this function is not in operation, the device looks for the largest signal below the process connection.
