Multi-Point Linearization (Linear)
Meters are set up at the factory for linear function with 2-point
linearization. Up to 32 linearization points can be selected for PV under
the linear function. The multi-point linearization can be used to linearize
the display for non-linear signals such as those from level Sensors used
to measure volume in odd-shaped tanks or to convert level to flow using
weirs and flumes with complex exponent.
If the dual-scale Level feature has been selected, the menus for PV1 &
PV2 are enabled. PV2 can be programmed with up to 8 linearization
points.
Auto-Zero (Auto 0)
Auto-zero corrects for drift that can occur over time that causes the
input signal to slowly change. The meter will continue to read zero
despite slow and small changes to the input signal. The auto-zero value
represents the percent of full scale drift that the meter will correct.
Under normal circumstances, when the signal increases quickly, by an
amount greater than the auto-zero percent of full scale, the value will
not be adjusted for. Slow signal changes that occur over time at
increments less than the auto-zero value, will not register on the meter
(example: dust on a load cell or sensor drift over time).
