PD6600 Series Loop-Powered Process Meters
Instruction Manual
46
Meter
Operation
The meter can accept a 4-20 mA current signal and
display it in engineering units from -9999 to 99999 on
the top display or from -9,999,999 to 99,999,999 (with
commas, if desired) on the bottom display.
For example, a 4-20 mA signal could be displayed as
-50.00 to 50.00 on the top display.
The dual-line display can be customized to display the
process variable and other parameters in a wide vari-
ety of ways. Typically, the top display is used for the
process variable while the bottom display is used for
engineering units, custom tag, or process variable
percentage of full scale.
The 4-20 mA input can be scaled to display the pro-
cess in two different scales; for example: with
PV2
en-
abled, the top display could indicate level in feet and
the bottom display could indicate the volume in gal-
lons.

During operation, the programmable function keys op-
erate according to the way they have been pro-
grammed in the

The table under
the factory default settings for F1, F2, and F3.
A hint message may be enabled to provide a descrip-

their assigned function. See
Digital Input Operation
A digital input is standard on the meter. This digital in-
put is programmed identically to function keys F1, F2,
and F3. The input is triggered with a contact closure
between DI+ and DI-, or with an active low signal.
During operation, the digital input operates according
to the way it has been programmed in the
Advanced
Features
– User
menu.
Maximum/Minimum Readings
The max & min readings (peak & valley) reached by
the process can be displayed either continuously or
momentarily.
Display momentarily by pressing the F1 key (default)
or assigning to any of the other function keys or to the
digital input in the
User
menu.
Display continuously by pressing the
Enter
button
while the max/min is being displayed to lock the dis-
play. Press
Enter
again to unlock.
Any of the F1-F3 function keys (buttons) and the digi-
tal input can be programmed to reset the max & min
readings. The meters are set at the factory to display
the max reading by pressing the
Right Arrow/F1
but-
ton and to use the
Up-Arrow/F2
button to access the
Reset
menu. Press the
Right Arrow
button to cycle
through the available parameters to reset.
