CAUTION
Attempting an electronics trim without a Rosemount 8714D may result in an inaccurate transmitter. It
may also generate a DIGITAL TRIM FAILURE message. If this message appears, no values were
changed in the transmitter. Simply power down the transmitter to clear the message. If the trim was
completed, or no error message was generated, correction requires a Rosemount 8714D.

1. Set the Rosemount 8714D to simulate a flow rate of 30 ft/s.
2. Power up the transmitter with the Rosemount 8714D connected. Allow the electronics 30
minutes to warm-up before reading the flow rate.
3. Read the flow rate. It should be between 29.97 and 30.03 ft/s. If the reading is within this
range, return the transmitter to the original configuration. If the reading is not within this
range, continue to step 8.
4. Initiate an electronics trim with the LOI or HART communicator. The electronics trim
takes about six minutes to complete. No transmitter adjustments are required.

8714D Magnetic Flowmeter Calibration Standard
The Rosemount 8714D Magnetic Flowmeter Calibration Standard operates in conjunction
with 8712D, 8732C, or 8742C Magnetic Flowmeter Transmitters. This device simulates a
flowtube coil load. It accurately produces a simulated flow signal for the purpose of
transmitter calibration.
Required Equipment
• Current source (output and accuracy: 500mA ±5mA)
• Precision Resistor: measured to 5 significant digits, less than 10 ppm, and > 1 watt
• Nanovoltmeter (Agilent 34420A or equivalent)
