Diagnostics and Service
The Diagnostics and Service menu offers device and
loop tests as well as calibration options. The diagnostics
and service operations that are available vary widely
from device to device and are defined in the device
description.
The Test device menu lists the status as well as self and
master test of the device. Test device initiates a
diagnostic routine at the device and can report an
electronics failure, as well as other failures that can
affect performance.
Loop test is used to set the output of the device at a
specified analog value, and may be used to test the
integrity of the loop and the operation of indicators,
recorders, or similar devices in the loop.
Calibration is used to perform such operations as
performing a sensor trim, D/A trim, and scaled D/A trim.
Basic setup
The Basic setup menu provides quick access to a
number of configurable parameters including tag, unit,
range values, and damping.
The options available in the Basic setup menu are the
most fundamental tasks that can be performed with a
device. These tasks are a subset of the options available
under the Detailed setup menu.
The Tag alphanumeric identifies a specific device.
Changing the unit option affects the engineering units
that are displayed. Changing range values changes the
analog output scaling. Changing damping affects the
response time of the transmitter and is often used to
smooth the output when there are rapid input variations.
