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, including its optional backlight feature.
It can be easily scaled in the field using four push
buttons; with or without applying an actual calibration
signal. The PD662’s display will read up to 2999; we
call this 3½+ digits! The PD662 is housed in a rugged
NEMA 4X enclosure and is provided with one ½" NPT
pipe conduit hole.

The minimum input span is the minimum difference
between input 1 and input 2 signals required to com-
plete the calibration or scaling of the meter. The mini-
mum span is 0.40 mA.
If the minimum span is not maintained, the meter re-
verts to input 2, allowing the appropriate input signals
to be applied.

A decimal point may be set in any of three positions:
1.999, 19.99, 199.9. It may also be turned off: 1999
Pressing the Right or Up arrow moves the decimal
point one place to the right until no decimal point is
displayed, then it moves to the left most position.
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 number of points.

number of scale points (2-32), followed by the input
values and display values. If using square root input
signal conditioning, the number of points input menu
will not be present.
1. Press the Up arrow button to scroll to the Scale
menu (SCL) and press Enter.
2. If using linear input signal conditioning, enter the
number of scaling points (2-32).
3. The meter displays in1. Enter the value for input
1 (typically 04.00) and press Enter.
4. When the meter displays d1, press Enter. Enter a
corresponding display value for input 1, and
press Enter to accept.
5. The meter displays in2. Enter the value for input
2 (typically 20.00) and press Enter.
6. When the meter displays d2, press Enter. Enter a
corresponding display value for input 2, and
press Enter to accept.
Calibrating the Meter (Cal)
The meter can be calibrated to display the process in
engineering units by applying the appropriate input
signals. The use of a calibrated signal source is
required.
1. Press the Up arrow button to scroll to the
Calibration menu (CAL) and press Enter.
2. If using linear input signal 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 input signal,
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

Input Signal Conditioning Function
(Fnc)
The PD662 provides linear (from 2 to 32 points) and
square root input signal conditioning functions for in-
puts from linear, non-linear and differential pressure
transmitters.
Linear (Lnr)
Meters are set up at the factory for linear function us-
ing two-point linearization. Multi-point linearization
with up to 32 points may be used. The linear function
provides a display that is linear with respect to the in-
put signal between each set of input points.
Square Root (sqr)
The square root function is used to linearize the signal
from a differential pressure transmitter and display
flow rate in engineering units.
Information Menu (info)
The Information menu is located in the Advanced
Features menu; to access the Information menu see
Advanced Features Menu on page 14.
The Information Menu shows the software identifica-
tion number, the version number, and the calibration
temperatures. To determine the software version of a
meter:
1. Go to the Information menu (info) and press
Enter button.
2. The meter will automatically scroll through
the software release number and software
version. The meter temperatures at the time
of last internal calibration in °C and °F are
displayed for calibration troubleshooting.
Pressing the Enter, Right, or Up buttons will
progress the information display.
3. Following the information display, the meter
will exit the Advanced Features menu and
return to run mode.
Input Signal Filter (FIL)
The noise filter is available for unusually noisy signals
that cause an unstable process variable display. The
noise filter averages the input signal over a certain
period. The filter level can be set to low (LO), high
(HI), or off (OFF). The higher the filter setting, the
longer the averaging time and so the longer the
display will take to settle on its final value.
The filter contains a noise filter bypass feature so that
while small variations in the signal will be filtered out,
large, abrupt changes to the input signal are
displayed immediately.

Internal Calibration (ICal)
•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.
The internal calibration allows the user to scale the
meter without applying a signal. The use of a
calibrated signal source is necessary to perform the
internal calibration of the meter. Check calibration of
the meter at least every 12 months.
Notes:
•The signal source must have a full-scale
accuracy of 0.01% or better between 4
and 20 mA in order to maintain the
specified accuracy of the meter.
•Allow the meter to warm up for at least
15 minutes before performing the internal
calibration procedure.
The Internal Calibration menu is part of the Advanced
Features menu.
1. Press and hold the Menu button for 5 seconds to
enter the Advanced Features menu.
2. Press the Up arrow button to scroll to the Internal
Calibration menu (ICAL) and press Enter.
3. The meter displays 4.00 mA. Apply a 4.00 mA
signal and press Enter. The display flashes for a
moment while the meter is accepting the signal.
4. After the signal is accepted, the meter displays
20.00 mA. Apply a 20.00 mA signal and press
Enter. The display flashes for a moment while
the meter is accepting the signal.
Error Message (Err)
An error message indicates that the calibration
process was not successful. After the error message
is displayed, the meter will revert to input 2 calibration
settings. The error message might be caused by
inadvertently leaving the signal at the previous level
or not maintaining a 0.40 mA minimum span. Press
the Menu button to cancel the current calibration
process if necessary.

Maximum & Minimum Readings
(HI & LO)
The maximum and minimum (peak & valley) readings
reached by the process are stored in the meter since
the last reset or power-up. The meter flashes HI or LO
to differentiate between run mode and max/min
display.
1. Press Up arrow button to display maximum
reading since the last reset/power-up.
2. Press Up arrow again to display the minimum
reading since the last reset/power-up.
3. Press Enter to continue to display the Max or Min
display reading by disabling the Max/Min timeout.
The meter will continue to track new Max/Min
readings. Press Menu to exit the Max/Min
reading.
4. If Enter is not pressed, the Max/Min display
reading will continue to flash and time out after
ten seconds. The meter will return to display the
actual reading.
5. Press Right arrow button while in Max/Min Mode
to reset both Max and Min. Max/Min display
readings are reset to the current reading.
Reset Meter to Factory Defaults
If the meter has inadvertently been programmed to
behave in some undesirable manner, the best course
of action might be to reset the meter to factory de-
faults and re-program it from scratch.
Instructions to load factory defaults:
1. Enter the Advanced Features menu. See
Advanced Features Menu, page 14.
2. Press Up arrow button to display info menu.
3. Press Right arrow button when info is shown.
4. Press Enter button when rSt is shown.
Press Enter again when display flashes rSt.
Note: If Enter is not pressed a second time within
three seconds, rSt will stop flashing and the last
Enter press cancelled.
5. The meter goes through an initialization
sequence (same as on power-up), and loads the
factory default settings.

Troubleshooting
Due to the many features and functions of the meter,
it’s possible that the setup of the meter does not
agree with what an operator expects to see. If the
meter is not working as expected, refer to the
recommendations described below.
Troubleshooting Tips
Symptom Check/Action
No display or faint

1. Check connections.
2. Perform hard reset
by temporarily
shorting S+ and S-
terminals for a few
seconds.
