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.

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 8.
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

Signal Input Conditioning Function
(
Fnc
)
The PD662 provides linear and square root
signal input conditioning functions for inputs
from linear and non-linear transmitters.
Linear (
Lnr
)
Meters are set up at the factory for linear function using 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 input 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 Information
menu see Advanced Features Menu on page 9.
It shows software identification number, version
number, and 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 may take to
find 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.
