Model PD6000 Analog Input Process Meter 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
process variable, maximum or minimum value reached by the process,
or one of the set points.

Analog Output Calibration
To perform the analog output calibration it is recommended to use a
milliamp 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.
