after setting the control loop to manual, see “Setting the loop to manual” on page 40.
2. a. For 4-20 mA HART output, connect a reference meter to the transmitter by either
connecting the meter to the test terminals on the terminal block, or shunting
transmitter power through the meter at some point in the loop.
b. For 1-5 Vdc Low Power HART output, connect a reference meter to the V
out
terminal.
3. Select OK after connecting the reference meter.
4. Select OK at the SETTING FLD DEV OUTPUT TO 4 MA (1 Vdc) prompt. The transmitter
outputs 4.0 mA.
5. Record the actual value from the reference meter, and enter it at the ENTER METER
VALUE prompt. The Field Communicator prompts you to verify whether or not the
output value equals the value on the reference meter.
6. Select 1: Yes, if the reference meter value equals the transmitter output value, or 2: No
if it does not.
a. If 1 is selected: Yes, proceed to Step 7.
b. If 2 is selected: No, repeat Step 5.
7. Select OK at the SETTING FLD DEV OUTPUT TO 20 MA (5 Vdc) prompt, and repeat Steps
