Model PD6200 Analog Input Rate/Totalizer Instruction Manual

Low-Flow Cutoff (CutofF)

The low-flow cutoff feature allows the meter to be programmed so that

the often-unsteady output from a differential pressure transmitter, at low

flow rates, always displays zero on the meter.

The cutoff value may be programmed from 0 to 999999. The meter will

display zero below the cutoff value. Programming the cutoff value to zero

disables the cutoff feature.

Analog Output Programming (AoutPr)

The Analog Output Programming menu is used to program the behavior

of the 4-20 mA output. The following parameters and functions are pro-

grammed in this menu:

1. Source: Source for generating the 4-20 mA output (e.g. PV)

2. Overrange: Analog output value with display in overrange condition

3. Underrange: Analog output value with display in underrange condition

4. Break: Analog output value when loop break is detected

5. Max: Maximum analog output value allowed regardless of input

6. Min: Minimum analog output value allowed regardless of input

7. Calibrate: Calibrate the internal 4-20 mA source reference used to

scale the 4-20 mA output

Analog Output Source

The source for generating the 4-20 mA output may be assigned to the

rate/process variable, total, grand total, maximum or minimum value

reached by the rate/process, or one of the set points, or the Modbus PV

input.

Analog Output Calibration

To perform the analog output calibration it’s recommended to use a mil-

liamp meter with a resolution of at least 0.1 µA to measure the output

current. The values saved internally during this procedure are used for

scaling the 4-20 mA output in the

Setup menu.
