Introduction
These loop-powered 1/8 DIN digital panel meters can
be installed virtually anywhere to provide convenient
and informative display of any 4-20 mA signal. One of
the most convenient features of these instruments is
their dual line display which is typically used to display
the process variable on the 5-digit alphanumeric top
line and the units of measure or a tag on the 8-digit
alphanumeric bottom line. Another common setup is
to display the input in one scale on the top line (such
as feet) and in another scale on the bottom line (such
as gallons). Both of these lines use 14-segment, al-
phanumeric characters for clear indication of tags,
units or alarm messages.
Further enhancing the display on these instruments is
a 20-segment bargraph available on the PD6604/8
that also includes a numeric value of the percentage
the bargraph represents.
These loop-powered meters can be installed virtually
anywhere because they get their power from the 4-20
mA loop and therefore require no separate power
source. And they only drop 1.5 V (4.5 V with back-
light), so they add very little burden to the loop. Addi-
tional features that allow these instruments to be in-
stalled virtually anywhere include a NEMA 4X, IP65
front panel, an operating temperature range of -40 to
167°F (-40 to 75°C) (for safe area products), confor-
mally coated PCBs, and a backlit LCD that can be
read in bright sunlight or dimly lit areas. Finally, there
are intrinsically safe and nonincendive versions of
these instruments that can be installed in hazardous
areas.
Free, PC-based, MeterView XL software that con-
nects to the meter via a micro USB cable is available
for programming and setup of the meters.
All models come equipped with two open collector
outputs and are available with two solid state relays
and isolated 4-20 mA analog output options. The
open collector outputs are useful for alarm indication
or pulse output. The relays can be programmed for
alarm indication, on/off control, or pump alternation.

Safe Area Current Loop (4-20 mA)
Connections
•PD6606 and PD6608 installation must be
performed in accordance with Control Drawing
LIM6600-2 in order to meet agency approval
ratings.
Signal connections are made to a six-terminal con-
nector labeled SIGNAL. See Connectors Labeling on
page 12. The following figures show a 4-20 mA cur-
rent loop connected to the meter. Figure 9 shows the
connection without the backlight and Figure 10 shows
the connection with the backlight (the backlight can be
disabled/enabled in the SYSTEM menu). The meter is
powered by the 4-20 mA current loop.
There are no switches or jumpers to set up for the
input. Setup and programming is performed through
the front panel buttons or PC-based software.

The current input is protected against current
overload up to 1 amp. The display may or may not
show a fault condition depending on the nature of the
overload.
Safe Area Digital Input Connection
A digital input is standard on the meter. This digital
input is connected with a normally open contact
across DI+ and DI-, or with an active low signal ap-
plied to DI+ and DI-.

Setup and Programming
The meter is factory calibrated prior to shipment to display
0.00 to 100.00, which corresponds to the 4-20 mA input.
The calibration equipment is traceable to NIST standards.
Overview
There are no jumpers to set; setup and programming
is done through the front panel buttons or PC-based
software.
The meter may be powered via the micro-USB
connection located on the right side of the meter for
the purposes of programming only. The backlight will
not work while the meter is powered via the USB
connection.
MeterView XL Programming
Software
The fastest and easiest way to program the meter is
using the free Meterview XL programming software.
This software greatly simplifies the programming pro-
cess and also allows the user to save configuration
files for later use.
The meter connects to the PC via a provided micro-
USB cable and is powered by the USB connection, so
no additional power is needed during programming.
For detailed programming software instructions
or to download MeterView XL software, visit
predig.com/meterviewxl.
•Care should be exercised to avoid ground loops
when connecting the USB to an active loop (e.g.
power supply, transmitter, loop-powered meter,
etc.). It is recommended to connect the (mA+)
terminal of the meter to the (-) terminal of a two-
wire transmitter and the (mA-) to the (+) of the
next device in the loop or to the (-) terminal of the
power supply.

Setting Numeric Values
The numeric values are set using the Right and Up-
Arrow buttons. Press Right-Arrow to select next digit
and Up-Arrow to increment digit value. The selected
digit will flash.
Press and hold Up-Arrow to auto-increment the
display value. If you have made a mistake or would
like to enter a new value, select the left-most digit and
press and hold the Right-Arrow button until all digits
reset to zero.
Press the Enter button at any time to accept a setting
or Menu button to exit without saving changes.
Note: the underscore in the graphic below is provided
to show which digit would be flashing.
Scaling the 4-20 mA Input (SCALE)
The 4-20 mA input can be scaled to the appropriate
values for a given application. The 4 mA input
(input 1) should have a corresponding display value
(display 1) which represents the low end of the pro-
cess value range being measured by the transmitter.
Likewise, the 20 mA input (input 2) should have a
display value (display 2) which represents the high
end of the process value range.
For example: If the meter is used to display the level
of a 100 foot tall tank, the transmitter will send a 4 mA
signal when the tank is empty and a 20 mA signal
when the tank is full. The meter should be scaled
such that 4 mA corresponds to a display of 0 and 20
mA to a display of 100. If the application required the
meter to display how much room was left in the tank,
the meter could be reversed scaled such that a 4 mA
input displays 100 and a 20 mA input displays 0.
Processes which require a non-linear scale can be
accommodated using the linear (LINEAR), exponent
(EXPONENT), square root (SQROOT), and round hori-
zontal tank (RH TANK) functions available in the
Advanced menu. See Signal Input Conditioning
Functions (FUNCTION)on page 30.
A signal source is not needed to scale the meter;
simply program the inputs and corresponding display
values.
