4.3.2 Configure outputs
The Rosemount 8600D is digitally adjusted at the factory using precision equipment to
ensure accuracy. You should be able to install and operate the flowmeter without a D/A
Trim.
Analog output
For maximum accuracy, calibrate the analog output and, if necessary, trim for your system
loop. The D/A Trim procedure alters the conversion of the digital signal into an analog 4–20
mA output.
Range values
Enables you to maximize resolution of analog output. The meter is most accurate when
operated within the expected flow ranges for your application. Setting the range to the
limits of expected readings will maximize flowmeter performance.
The range of expected readings is defined by the Lower Range Value (LRV) and Upper Range
Value (URV). Set the LRV and URV within the limits of flowmeter operation as defined by the
line size and process material for your application. Values set outside that range will not be
accepted.
Loop test
Verifies the output of the flowmeter, the integrity of the loop, and the operation of any
recorders or similar devices. Conduct the loop test after the flowmeter is installed in the
field. If the meter is located in a loop with a control system, the loop will have to be set to
manual control before the loop test is performed.
Loop Test allows the device to be set to any output between the Low Alarm and High Alarm.
Alarm jumper
Allows you verify the alarm jumper setting.
D/A trim (Digital-to-Analog trim)
Enables you to check and trim the analog output in a single function. If the analog output is
trimmed, it will be scaled proportionally through the range of the output. To trim the digi-
tal-to-analog output, initiate the D/A Trim function and connect an ammeter to the loop to
measure the actual analog output of the meter. Follow the on-screen functions to complete
the task.
