2 MATH CONFIGURATION 2.1 Introduction Overview. • Four user-configurable math blocks – can be used independently or cascaded together. • Each math block can be configured to perform one of seven functions: Standard math block (arithmetic operations) – add, subtract, divide, multiply, high select, low select and median Relative humidity (RH) –...
– see Section 3.5 of the C1300 Linearizer Type None User Guide (IM/C1300). Therefore the formula used internally within the C1300 is: where: a = linearized flow signal The linearized flow signal is produced by the transmitter or derived from the signal linearized within the C1300.
