Alarm level select
FastKeys
Allows you to select the alarm level of the transmitter. Either Rosemount standard or
NAMUR compliant.
Alarm/sat levels
FastKeys
Displays alarm and saturation mA output levels.
Note
Alarm and saturation levels can be found in the specifications section.
Scaled D/A trim
FastKeys
enables you to calibrate the flowmeter analog output using a different scale than the
standard 4-20 mA output scale. Non-scaled D/A Trimming (described above), is typically
performed using an ammeter where calibration values are entered in units of milliamperes.
Both non-scaled D/A trimming and scaled D/A trimming allow you to trim the 4-20mA
output to approximately ±5% of the nominal 4mA end point and ±3% of the nominal 20mA
end point. Scaled D/A Trimming allows you to trim the flowmeter using a scale that may be
more convenient based upon your method of measurement.
For example, it may be more convenient for you to make current measurements by direct
voltage readings across the loop resistor. If your loop resistor is 500 Ohms, and you want to
calibrate the meter using voltage measurements made across this resistor, you could
rescale your trim points from 4-20mA to 4-20mA x 500 ohm or 2-10 Vdc. Once your scaled
trim points have been entered as 2 and 10, you can now calibrate your flowmeter by
entering voltage measurements directly from the voltmeter.
Recall factory Trim
FastKeys
Enables you to return to the original factory trim values.
Pulse output
FastKeys
Enables you to configure the Pulse Output.
Note
The Field Communicator will allow configuration of the pulse features even if the pulse
option (Option P) was not ordered.
