from the transmitter’s surroundings. If the user knows how fast the level can change in the vessel (i.e. inches per second) then this parameter should be set at a rate that the level in the vessel cannot suddenly jump to. See section “7.2 Features” for more details.

Trim Sensor:

This menu can be used to recalibrate the transmitter.

There is no need to recalibrate the instrument simply use the “Change Range” menu and change the LRV and URV as desired.

If the need arises to use this menu then level simulation will be required at 0 and 100 percent.

Offset:

This parameter simply adds a digital value to the measuring range or span it does NOT shift or move the measuring range. See section “7.2 Features” for more details.

The span will not change and the 4/20mA will not shift from its original calibrated points. This value also affects the reading for interface level when available.
