Input Data Conditioning Function Menu (
Functn
)
The
Function
menu is used to select the input-to-output transfer function applied to the input data: linear, square root,
programmable exponent, or round horizontal tank volume calculation. Multi-point linearization (for PV1 and PV2) is
part of the linear function selection. Scanners are set up at the factory for linear function with 2-point linearization.
The linear function provides a display that is linear with respect to the input data (e.g 0.000 = 0.000, 10.000 = 10.000,
and then 5.000 = 5.000).
Linear Function Menu (
Linear
)
Scanners are set up at the factory for linear function with 2-point linearization. Up to 32 linearization points can be
selected for PV1 and PV2 under the
Linear
function in the
Advanced Features
menu. The multi-point linearization can
be used to linearize the display for non-linear signals such as those from level transmitters used to measure volume
in odd-shaped tanks or to convert level to flow using weirs and flumes with complex exponents.
Note: Multi-point Linearization applies to PV1 and PV2 only. All other PVs use two linearization points.
