INTRODUCTION
The PD662 NEMA 4X, CSA Certified loop-powered meter is perfect for
applications where a simple, inexpensive display is required, and AC
power is not available. The PD662 derives all its power from the 4-20 mA
loop. The PD662 is scaled using four push buttons and can be done
without applying an actual calibration signal. The PD662’s display will
read up to 2999; we call this 3½+ digits! The loop-powered backlighting
option lets you see the display under any lighting condition and is
powered completely from the 4-20 mA loop. This means there is no need
for additional wiring and never any batteries to change. Multi-point
linearization with up to 32 points and the square root function allow for
conditioning of signals from non-linear transmitters without adding
external components to the system.
The PD662 is housed in a rugged NEMA 4X enclosure and is provided
with one ½" NPT pipe conduit hole. The PD662 is also available with an
optional DC-powered heater that allows the PD662 to operate in
temperatures as low as -55°C.

Mounting
The PD662 can be wall mounted using the mounting holes beneath the
cover screws. A ½” NPT pipe conduit hole is provided. It can be panel
mounted with the addition of the PDA6624 panel mount kit. It can also
be pipe mounted by using the PDA6845 pipe mount kit.
Refer to Mounting Dimensions, page 28 for details on wall or panel
space requirements.
The unit shall be installed in a way that will prevent
any accidental contact of the internal meter circuits
and power supply lines.
Cable suitable for outdoor use and a CSA Approved
gland rated 4X, or a suitable conduit and a CSA
Approved connector rated 4X, is intended to be used
in final installation.
Metallic conduit shall be reliably bonded to protective
earth/ground without creating any ground loop.
PD662 Connections
Disconnect power before opening the unit.
To access the connectors, remove the enclosure cover and unscrew the
two captive stainless-steel screws on the rear mounting board. Remove
the meter assembly from the enclosure. Signal connections are made to a

SETUP AND PROGRAMMING
 There is no need to recalibrate the meter for
milliamps when first received from the factory.
 The meter is factory calibrated for milliamps
prior to shipment. The calibration equipment
is certified to NIST standards.
Overview
There are no jumpers involved in the setup process of the meter.
Setup and programming is done through the front panel buttons.
After all connections have been completed and verified, apply power to
the loop.

to exit without saving changes.
The decimal point is set using the Right or Up arrow button in the
Setup-decimal point menu.
Programming the Meter
It is very important to read the following information, before proceeding
to program the meter:
 There is no need to recalibrate the meter for milliamps when first
received from the factory.
 The meter is factory calibrated for milliamps prior to shipment.
The calibration equipment is certified to NIST standards.
 Use the Scale (SCL) menu to enter scale parameters without
applying a live signal.
 Alternatively, use the Calibrate (CAL) menu to apply a signal from a
calibrator or a 4-20 mA transmitter to calibrate the meter.
Inputs may be calibrated or scaled to any display within the range of the
meter.
Additional parameters, not needed for most applications, are viewed
and programmed with the Advanced Features menu, see Advanced
Features Menu on page 20.

Scaling the Meter (SCL)
The 4-20 mA input can be scaled to display the process in engineering
units.
A signal source is not needed to scale the meter; simply program the
inputs and corresponding display values.
If using linear signal input conditioning, enter the number of scale points
(2-32), followed by the input values and display values. If using square
root signal input conditioning, the number of points input menu will not
be present.
Number of Points (npt)
Set the number of linearization points used in the Scale menu. 2 to 32
points may be used. The Scale menu is entered after entering the num-
ber of points
Minimum Input Span
The minimum input span is the minimum difference between input 1 and
input 2 signals required to complete the calibration or scaling of the
meter. The minimum span is 0.40 mA.
If the minimum span is not maintained, the meter reverts to input 2,
allowing the appropriate input signals to be applied.

Calibrating the Meter (Cal)
To scale the meter without a signal source,
refer to Scaling the Meter (SCL), page 18.
The meter can be calibrated to display the process in engineering units
by applying the appropriate input signal.
The use of a calibrated signal source is strongly recommended.
1. Press the Up arrow button to scroll to the Calibration menu (CAL)
and press Enter.
2. If using linear signal input conditioning, enter the number of
calibration points (2-32).
3. The meter displays in1. Apply a known signal and press Enter.
The display will flash while accepting the signal.
4. When the meter displays d1, press Enter. Enter a corresponding
display value for the signal input, and press Enter to accept.
5. The meter displays in2. Apply a known signal and press Enter.
The display will flash while accepting the signal.
6. When the meter displays d2, press Enter. Enter a corresponding
display value for the signal input, and press Enter to accept.
Recalibrating the Internal Calibration Reference (Ical)
The Internal Calibration (ICAL) menu, located in the Advanced Features
menu, is used to recalibrate the internal calibration reference.
Recalibration is recommended at least every twelve months. Refer to
Internal Calibration (ICal), page 23 for instructions.
