Model PD6060 Dual-Input Process Meter Instruction Manual
85
METER OPERATION
The meter is capable of accepting two input channels (A and B) of either
current (0-20 mA, 4-20 mA) or voltage signals (0-5 V, 1-5 V, 0-10 V,
±
10
V) and displaying these signals in engineering units from -99999 to
999999 (
e.g. a 4-20 mA signal could be displayed as -50.000 to 50.000).
A math function channel (C) is available to perform operations on channel
A and B, with adder and factor constants, and display the results.
Engineering units or tags may be displayed with these three channels.
The dual-line display can be customized by the user. Typically, the upper
display is used to display the math channel C, while the lower display is
used to alternate between displaying input channels A and B.
Additionally, the meter can be set up to display any input or math channel
on the upper display and a unit or tag on the lower display. The relays
and analog output can be programmed to operate based on any input or
math channel.
