User Manual
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 CH2 in
Current Measure mode
A second input channel can also be used, to transfer data
between three points in the signal path and may be
calibrated at the same time, as in the example that
follows.
•
When calibrating a process transmitter that is
HART® enabled the second input channel could
be the HART® channel. The HART® channel reads
the Primary Variable (PV) value from the sensor in
the process transmitter this would allow the
pressure sensor to be calibrated at the same time
as the current loop output
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.
