Top: 0.7" (17.8 mm)
Bottom: 0.4" (10.2 mm)
Display may be programmed to turn red
and flash a user-defined message on
Powered by 4-20 mA loop. Intensity
varies with signal level.
5 digits (-9999 to 99999) or 5 characters
(all capital & most lower-case letters)
8 digits (-9,999,999 to 99,999,999;
separated by commas) or 8 characters
(all capital & most lower-case letters)
20 segments, numeric percent indication
at top (PD6604 & PD6608 only)
Up to four decimal places on top line and
up to seven decimal places on bottom
line
Commas to indicate 1000s
(e.g. 88,987,628) on bottom line
Feature
The input can be displayed in different
scales on the top and bottom lines. For
instance, the top line could display the
input in height and the bottom line could
display that same input in volume.
Programmable: red backlight, flashing
display, alarm symbol (!); (symbols not
available on bargraph models). Bargraph
segment flashes on alarm.
Programmable: 8 characters maximum;
displayed every 10 sec for 1 sec on
bottom line. May be turned off.

Noise Filter
Averages the input signal over a period of
time between 1 and 16 seconds to dampen
the effects of a noisy signal that causes a
jumpy display.
Filter Bypass
0.0 to 99.9% of full scale. Input signal
changes that are greater than bypass value
are displayed immediately.
Recalibration
Recalibration is recommended at least every
12 months.
Max/Min
Display
Max/min readings reached by the process are
stored until reset by the user or until power to
the meter is turned off.

zero.
Transparency
The meter does not interfere with
existing HART communications; it
displays the 4-20 mA primary variable
and it allows the HART communications
to pass through without interruption. The
meter is not affected if a HART
communicator is connected to the loop.
The meter does not display secondary
