4 DOCUMENTATION
This chapter describes the Documenting functions available with the
Druck DPI611 calibrator as follows:
• ANALYSIS
• RUN PROCEDURE
4.1 ANALYSIS
The Analysis function takes readings from two or more DPI611
channels to calibrate the transfer characteristic of the device being
tested. One channel is the Reference channel and is used as follows:
• It provides a measure of the input signal to the device.
• If the device is a pressure transmitter the Reference channel
would be Pressure, measuring the input pressure to the
device.
The other channel is the Input channel and is used as follows:
• Measures the output signal from the device
• If calibrating a process transmitter it could be the electrical
channel in Current Measure mode.
Any active channel that is not defined as Reference is Input by default.
There must be one Reference channel and at least one Input channel
defined for the Analysis function set-up to be correct.
At each value the Analysis function calculates the difference of each
Input channel to the ideal transfer characteristic and compares this to
a tolerance limit.
• The deviation is shown in %Span or %Rdg
