Figure 14- Custom Value/Temperature display mode
The definition of Custom variable (CV) is only possible through HART protocol connection to the device
and there is no way to define them using the keys on the device.
Single Selected Variable Display Mode
In this mode only one variable of Level, Distance, Mass or Custom variable is displayed; and like other
screens the value of transmitter’s current output is also displayed and the percent of current output in both
numeric and graphical presentations are available. The user has also the option to use this percent value
as the main value to be displayed.
Echo Curve Display Mode
In this mode, all received waves by the device in a defined time range are displayed; also by drawing the
Threshold Level line, the user can see the waves that are identified as target levels.
In addition to the curve, there are Noise to Signal Ratio/Gain, Temperature, Power Percent/Number of
Pulses, Dead Band size. Distance to the Liquid and Liquid Level parameters, from top-Right to bottom-Left
accordingly.
