5.5 External analogue input configuration
The naming and configuration of external analogue inputs is treated identically to
internal process variables. Two external analogue inputs are provided on the
instrument. The process variables associated with these inputs are identified as E1 and
E2 ( the internal transducer process variables are I1 to I4 ). The name and engineering
units for these variables are modified using the UDEF menu entry.
The procedure for configuring the external inputs is given in table 5.8. Definition of the
input scaling ( calibration ) of the external analogue inputs is accomplished via the
MANUAL CAL menu ( see section 4.16 ).
