Description
Rate of Change (RoC) Filter:
This parameter helps ignore erroneous readings
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.
