The “Scroll” option will vary depending on how many outputs are configured.

Rate of Change (RoC) Filter: The RoC filter is a continuous monitor of how fast (the rate) the level is rising and falling. It is also an excellent tool to help eliminate any temporary spontaneous noise that may be present in-field. For example if the level in a tank cannot rise or fall faster than 30.0 in/s then the setting for the RoC filter should be set to 15.0 in/s or less to help filter/ignore erroneous readings. Note: The engineering units will change according to units selected (i.e. cm/s) – (exclusively for models LTM-250/350).

Offset: The offset is a digital number that gets added to both the LRV and URV to account for any distance below the sensor probes measuring distance. For example if the offset is changed from “0.00in” to “2.00in” the ‘Level’ on the main screen will show “2.00in” at 4.00mA and the 20.00mA value will simply have 2.00 inches added to it.

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