The MATH function (y = Ax + B) enables measuring any physical quantity in:
- Volts
(0 - 10 V process or high-voltage probe, for example)
- Amperes
(current loop 4 - 20 mA or current clamp, for example)
- Frequency
(output measurement, rotation speeds, for example)
- Ohms
(resistive position, for example)
and converting it and to assign the adequate unit, to obtain the direct reading of
the original parameter on the instrument. Depending on the parameter measured,
the device calculates the related MATH function.
The programming takes place in 4 phases:
Selection of parameter X measured (V, A, , Hz)
Definition of coefficient A of function y = Ax + B
Definition of coefficient B of function y = Ax + B
Definition of physical unit to be displayed
Coefficients A, B and the unit are programmable for each amount
measured (V, A,
, Hz).
The MATH mode is configured in the MATH function in the Configuration Menu.
