PD6830 Pulse Input Rate/Totalizer Instruction Manual

Scaling the Meter (SCale)

The pulse input can be scaled to display the process variable in engineering units.

A signal source is not needed to scale the meter; simply program the inputs and

corresponding display values.

A programmed scaled input will work with Automatic Unit Conversions as described

on page 46. The units for the display values that must be entered are a combination

of the programmed Rate Unit and the time unit (Time UNIT) entered in the Scale

menu.

For example, if the Rate Unit is gallons, and the time unit (Time UNIT) is seconds,

the units for the display values entered in the Scale menu are gallons/second.

For instructions on how to program numeric values see page 30.
