How do formulas relate inputs to dimensions?

Formulas can be constructed that make dimensions equal to channel
inputs, or that calculate dimensions from one or more channels using
math, logic or other functions.

Formulas can be constructed by the user to display:

One dimension based on one channel input.

A=C1

One dimension based on multiple channel inputs.

A=C1+C2

Multiple dimensions based on one channel input.

A=C1
B=2*pi*C1

Multiple dimensions based on multiple channel inputs.

A=C1
B=C2
C=C1*C2

Visible or hidden dimensions?

Dimensions can be visible to display values or hidden to perform
operations.

Visible dimensions

Visible dimensions are used with basic and advanced functions to
calculate, display and store values in the ND 2100G database.

Example:

A = 2*pi*sqrt(B)

This formula uses visible dimension B in a formula with other functions
to calculate and assign a value to visible dimension A, which is stored
later in the ND 2100G database by pressing the ENTER key or
executing a Trip function.

Hidden dimensions

Hidden dimensions are used with basic and advanced functions to
perform operations.

Example:

H1 = if(fail(),Relay(1,1),Relay(1,0))

This formula uses the pass/fail state of all tolerance tests to control the
state of output relay 1. Since values are not assigned to operations, no
value will be stored in the ND 2100G database.
