Measurement Mode
Normally, the Measurement Mode does not need to be changed. The
transmitter is pre-configured according to the specified model. See “Basic
Configuration Parameters” on page 5-4 for more information.
Process Conditions
Select the Rapid Level Changes check-box only if the surface is moving
quickly up or down at rates over 1.5 in./s (40 mm/s).
Dielectric Constant/Dielectric Range
The dielectric constant of the product is used for setting the appropriate signal
amplitude thresholds, see Section 7: Service and Troubleshooting for more
information on amplitude threshold settings. Normally, this parameter does
not need to be changed for level measurements. However, for some products,
measurement performance can be optimized by setting the proper product
dielectric constant.
For Interface Level measurements, the dielectric constant of the upper
product is essential for calculating interface level and the upper product
thickness. By default, the Upper Product Dielectric parameter is about 2.
Set the Upper Product Dielectric Constant to a value that corresponds to
the current product.
