6.2.6Range values for milliamp output

Range values are the flow rates represented by the milliamp output at 4 mA and at 20 mA.

To set range values, use the menu below and follow these steps:

1Process variables

2Diag/service

3BASIC SETUP

4Detailed setup

5Review

1Tag

2PV unit

3ANALOG RANGE VALS

4Freq factr

5Rate factr

1PV URV

2PV LRV

1.At the online menu, choose 3 (basic setup).

2.At the basic setup menu, choose 3 (analog range values).

3.Choose the upper or lower range value for setting.

To set the upper range value, which is the flow rate represented by the output at 20 mA, choose 1 (primary variable upper range value), or

To set the lower range value, which is the flow rate represented by the output at 4 mA, choose 2 (primary variable lower range value).

4.Enter the desired range value, then press F4 (enter).

5.To send the range values to the flowmeter, press F2 (send).

6.2.7Pulse output scaling

The pulse output produces a frequency proportional to the flow rate. Pulse output scaling requires entry of frequency and flow rate values.

To scale the pulse output, use the menu below and follow these steps:

1Process variables

2Diag/service

2PV unit

3Analog range vals

4FREQ FACTR

5RATE FACTR

1.At the online menu, choose 3 (basic setup).

2.At the basic setup menu, choose 4 (frequency factor).

3.Enter a value for the frequency in pulses per second (Hertz) that corresponds to the maximum flow rate, then press F4 (enter).

4.When the HART Communicator display returns to the basic setup menu, choose 5 (rate factor).

5.Enter the maximum value of the flow rate, then press F4 (enter). The entered value corresponds to the frequency that was entered in Step 3.

6.To send the pulse output scaling to the flowmeter, press F2 (send).
