Chapter 10. Analysis
10.3 Function
The
Analysis Setup
screen shows the selected
CH1
and
CH2
calibrator functions and units. The
required functions needed in the Analysis application, need to be selected in the Calibrator
application prior to running Analysis. For example, to run analysis on a pressure transmitter with
a 4 to 20 mA output,
CH1
can be configured to
INT
Pressure and
CH2
to
Current Measure
(with 10/24 V power if required). Select the required types of measurement units.
Figure 10-2: Analysis Function screen
The
INPUT
and
OUTPUT
functions can be interchanged using the toggle
softkey.
10.3.1 START/END Values
The measurement range for the input and output channels is defined by setting a
START
(Low)
and
END
(High) value for each channel. The default values displayed are usually the negative
and positive full-scale values of the related function. When Current Measure is selected, the
default
START
and
END
values, are 4 and 20 mA. When entering
START
and
END
values, any
value entered which falls outside the full-scale limits of the selected function will be rejected.
10.3.2 LINEARITY
The transfer characteristic from
INPUT
signal to the
OUTPUT
signal can be either:
The default mode is Linear.
Linear
- when the transfer characteristic is a directly proportional relationship.
Square Root
- when the transfer characteristic has a square-root relationship. This is
commonly found in flow sensors.
