Analog Input
AI2 (Pressure)
User Selection (Circle one) Results (Enter Here)
Electrical Configuration Sink Source (i.e., powered by the meter) If the analog input is configured for
source mode, then it must be at the bottom of the loop (stack).
Pressure Type gage absolute
Atmospheric Pressure
(if absolute selected)
Minimum Input
(pressure corresponding to
4mA input)
_____ psig
(if gage is selected)
______psia
(if absolute is selected)
Maximum Input
(pressure corresponding to
20mA input)
______psig ______psia
Low Alarm ______psig ______psia
High Alarm ______psig ______psia
Note: If the pressure is at or outside these limits, an alarm is generated
Note: Pressure is required for optional meter internal diameter Pressure expansion correction. If a pressure transmitter is connected to the meter, select Live for this option. If a
pressure transmitter is not connected to the meter but pressure expansion correction is required, select Fixed. You will enter in a fixed pressure on a later page. If the correction is
not required, select Not used.
Digital Input
DI1
User Selection (Circle one) Results (Enter Here)
The Digital Input (DI1) may used to bring prover detector switches into the meter for “proving” against a ball prover (required only if input is used for
gated calibrations). Note: When using the digital method, the frequency output is not used for proving.
Calibration Type Gated Timed
Is DI1ForCalActiveLow Active High Active Low
Is DI1ForCalStateGated Edge State
