ANALOG OUTPUT TRIM

The Analog Output Trim commands allow you to adjust the transmitter’s
current output at the 4 and 20 mA points to match the plant standards. This
command adjusts the digital to analog signal conversion (see Figure 4-1 on
page 4-3).

Digital-to-Analog Trim

HART Communicator

To perform a digital-to-analog trim with a HART Communicator, perform the
following procedure.

1. From the

Home

screen, enter the fast key sequence shown. Select

after setting the control loop to manual, see “Setting the Loop to Manual”
on page 3-2.

2. Connect an accurate reference ammeter to the transmitter at the

Connect Reference Meter

prompt. Connect in series with the signal

loop, or shunt power through the reference meter at some point.

3. Select

after connecting the reference meter.

4. Select

at the

Setting Fld Dev Output To 4 MA

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 HART 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

at the

Setting Fld Dev Output To 20 MA

prompt, and repeat

Steps 5 and 6 until the reference meter value equals the transmitter
output value.

8. Select

after the control loop is returned to automatic control.
