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
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 4 mA and 20
mA.
Alarm Jumper
Alarm Jumper lets you verify the alarm jumper setting.
D/A Trim (Digital-to-Analog 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 digital-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.
Alarm Level Select

NAMUR compliant.
