Input Signal Conditioning Functions (

FUNCTION

) 

The 

Function

 menu is used to select the input signal conditioner applied to the input: linear, square root, programmable 

exponent, or round horizontal tank volume calculation. Multi-point linearization is part of the linear function selection. 

Meters 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 signal. 

Using MeterView XL 

MeterView XL makes programming the input signal conditioning functions quick and easy. Go to the input/scale menu 
and select the desired function from the drop down menu in the “scale input” section.
