10.1 Overview
The
Analysis
application takes readings from the two channels, to calibrate the transfer
characteristic of the device being tested. One channel is set as the Input channel and the other
channel is set as the Output channel.
The Input channel provides a measure of the input signal to the device under test (DUT). For
example, if calibrating a pressure transmitter, the Input channel could be the DPI 610E Internal
Pressure which measures the supplied pressure to the DUT.
The Output channel measures the output signal from the DUT. If calibrating a 4 to 20 mA process
transmitter, the output channel would be the Current Measure.
By default, the Analysis application uses the functions and measurement units set up in CH1 as
the Input and the function set up in CH2 as the output. This means that the required functions for
analysis have to be selected in the Calibrator screen before starting the Analysis application
(Refer to “Calibrator Tasks” on page 63 for more details.)
There is however the option to toggle between Input and Output selection for both functions.
For the Analysis application to run, both channels must be enabled with a valid function i.e. any
function option except “None”.
At each test point value, the Analysis function calculates the difference of each Output channel
to the ideal transfer characteristic and compares this to a user specified tolerance limit. This
deviation is calculated and can be displayed in different user defined formats. In addition, the
tolerance test result is shown as a Pass or Fail.
