Specifications
Except where noted all specifications apply to operation at +25°C.
Display
Display
Dual-line LCD with backlight.
Both lines 14-segment alphanumeric.
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
alarm condition.
Backlight
Powered by 4-20 mA loop
Intensity varies with signal level
Top Display
5 digits (-9999 to 99999) or 5 characters (all
capital & most lower-case letters)
Bottom
Display
8 digits (-9,999,999 to 99,999,999; separated
by commas) or 8 characters
(all capital & most lower-case letters)
Bargraph
20 segments, numeric percent indication
at top (PD6604 & PD6608 only)
Decimal Point
Up to four decimal places on top display and
up to seven decimal places on bottom display
Commas
Commas to indicate 1000s
(e.g. 88,987,628) on bottom display
Dual-Scale
Feature
The input can be displayed in different scales
on the top and bottom displays. For instance,
the top display could display the
input in height and the bottom display could
display that same input in volume.
Alarm
Indication
Programmable: red backlight, flashing display,
alarm symbol (!); (symbols not available on
bargraph models). Bargraph segment flashes
on alarm.
Alarm
Message
Programmable: 8 characters maximum;
displayed every 10 sec for 1 sec on bottom
display. May be turned off.
Display
Update Rate
Ambient > -10°C: 1 Update/Second
Ambient = -20°C: 1 Update/2 Seconds
From -20°C to -40°C the update rate slows
down 1 second for every -2°C
(e.g. at -24°C, 1 update/4 seconds).
Overrange
Top: 99999; Bottom: 99,999,999 (flashing)
Underrange
Top: -9999; Bottom: -9,999,999 (flashing)

Front panel & Free PC-based USB
programming software
Enclosure &
Materials
Enclosure: 1/8 DIN, IP65, NEMA 4X front
panel, high impact plastic, NORYL®
polyphenylene ether & polystyrene blend
(PPE PS) resin, UL 94V-0, Color: gray
Gasket: silicone rubber
Faceplate: LEXAN® polycarbonate (PC) Film
Buttons: silicone rubber
Environmental Operating temperature range:
-40 to 75°C for safe area products
-40 to 70°C for hazardous area products
Storage temperature range:
-40 to 85°C
Relative humidity:
0 to 90% non-condensing;
Printed circuit boards are conformally coated.
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.
Tare
Tare function zeros out the meter to
accommodate for weight of a container.
Tare function can be assigned to a function
key or a digital input.
Password
Programmable password restricts
modification of programmed settings.
Non-Volatile
Memory
All programmed settings are stored in non-
volatile memory for a minimum of ten years if
power is lost.
Normal Mode
Rejection
64 dB at 50/60 Hz

Low-Flow
Cutoff
0.1 to 999,999 or disable. Point below at which
the display always shows zero.
HART
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 HART
variables.
