PM9607AP
INTRODUCTION
meter configurations possible with the SA9607M using the
PM9607AP module. Note that the values of the current
transformer’s resistor values need to change to make some of
the rated conditions possible. This will be covered in the
Analog Section.
This Application Note describes the functionality of the
SA9607M and the SA9607P metering integrated circuits using
the PM9607AP evaluation module. The SA9607 family is a low
cost solution specifically designed to meet the needs of
markets that require both live and neutral energy
measurement, in order to detect possible meter tampering.
Using the SA9607 family the meter manufacturer is able to
build a meter that measures the energy consumption, even
during a tamper condition, and records it to a mechanical
counter.
This application note will focus on the practical use of the
SA9607 family. More detailed information specific to the
SA9607M or SA9607P can be found in the applicable
datasheet.

THE SA9607 SERIES ENERGY METER ICS
The SA9607 family is characterized by its ability to measure
live and neutral power consumption simultaneously. A
correctly installed meter should measure equal amounts of
power consumption in the live and neutral phases. During
meter tampering the two measurements are no longer equal.
The SA9607 will use the larger of the two currents for the
energy measurement. Differences of more than 12% between
the live and neutral power measurements are indicated on the
SA9607’s ELT output which can drive a LED directly.
THE SA9607P MONOCHIP METER WITH ON CHIP
CALIBRATION
The SA9607P uses an external EEPROM to store calibration
data as well as meter specific settings. A major advantage of
the SA9607P is that no external trim-pots or resistor ladders
are required to calibrate the meter. This greatly enhances the
meter reliability and can improve meter production times if
used in an automatic meter calibration system.
The SA9607 are designed to drive mechanical counters
directly. The module is fitted with an impulse type counter that
increments with a single 71ms pulse. The SA9607 can also
drive low cost mechanical counters (stepper motors) that use
two consecutive pulses with opposing voltages to advance the
counter one position. The SA9607 outputs these two opposing
pulses in close succession, minimizing the chance of the
stepper motor being in the wrong phase after a power failure.
Calibration pulses, reverse power, earth loop tamper and
active channel are displayed with four LEDs fitted on the
module.
The SA9607P integrated circuit together with an external
EEPROM provides more meter setup features than the
SA9607M. Additional information regarding the meter (serial
numbers, client, and manufacture date) can also be stored in
the unused sections of the EEPROM memory. An IIC bus
based EEPROM is used to store configuration and meter
setup data for the SA9607P. The SA9607P will load this data
from the EEPROM during power up. During normal meter
operation it reloads periodically the data from the EEPROM.
The SA9607P never writes to the EEPROM. For more specific
configuration information please refer to the SA9607P
datasheet.
THE SA9607M PIN PROGRAMMABLE MONOCHIP
METER
Using the SA9607M, the rated conditions of the meter as well
as the LED pulse rate and counter resolution can be selected
for a particular meter design. The meter manufacture is thus
able to produce a range of meters utilizing the same counter
and the same metering constant with a single integrated
circuit. Calibration of the meter is done with trim-pots or
resistor ladders. Table 1 gives a short list of all the possible

PM9607AP
MODULE OVERVIEW
ANALOG SECTION
The analog (metering) interface described in this section is
designed for measuring 230V/60A with precision better than
Class 1.
The termination resistor on the second current channel is
adjustable by means of P2 to facilitate channel equalization
calibration. The termination resistor is chosen so that a 10W
trimpot in parallel will provide a sufficient channel range.
The most important external components for the SA9607
integrated circuit are the current sense resistors, the voltage
sense resistors and the bias setting resistor. The resistors used
in the metering section should be of the same type so
temperature effects are minimized.
Current Sensor Input Resistors
The resistors R8, R9 and R10, R11 define the current level into
the current sense inputs of the SA9607. The resistor values
are selected for an input current of 16µA on the current inputs
of the SA9607 at rated conditions. For a 60A meter at 2500:1
CT the resistor values are calculated as follows:
Current Input IIN1, IIP1, IIN2, IIP2
Two current transformers are used to measure the current in
the live and neutral phases. The output of the current
transformer is terminated with a low impedance resistor. The
voltage drop across the termination resistor is converted to a
current that is fed to the differential current inputs of the
SA9607.

The voltage drop across the CT termination resistor at rated
current should be at least 20mV. The CTs have low phase shift
and a ratio of 1:2500. The CT is terminated with a 3.6W resistor
giving a voltage drop of 86.4mV across the termination resistor
at rated conditions (Imax for the meter).

10R/2W
Voltage Input Ivp
The voltage input of the SA9607 (IVP) is driven with a current
of 14µA at nominal mains voltage. This voltage input saturates
at approximately 17µA. At a nominal voltage current of 14µA
allows for 20% overdriving. The mains voltage is divided with a
voltage divider to 14V that is fed to the voltage input pins via a
1MW resistor.
Voltage Divider
The voltage divider is calculated for a voltage drop of 14V.

Common mode and asymmetrical transients are attenuated
by the current setting resistors R8, R9 R10 and R11.
POWER SUPPLY
The PM9607AP module uses a transformer based power
supply to ensure flexibility for different counter drive
configurations. The maximum current that can be drawn by
the circuit is as follows:
Standard resistor values of R1, R2, R3 and R4 are chosen to
be 120kW , 120k
, 120k
and
W
W
W 10 .
The capacitor C4 is used to compensate for phase shift
between the voltage sense inputs and the current sense inputs
of the device, in cases where CTs with phase errors are used.
The phase shift caused by the CT may be corrected by
inserting a capacitor in the voltage divider circuit. To
compensate for a phase shift of 0.18 degrees the capacitor
value is calculated as follows:
The average power consumption of the module is usually less.
The current indicated in table 2 is worst-case peak pulse
current. The normal operating current of the module is closer
to 15mA. A 78LC05-voltage regulator is used to regulate the
voltage from the transformer. Two resistors R18 and R19
generate the analog ground voltage for the SA9607. The
SA9607 operates between 5 Volt and 0 Volt with its GND pin
connected to mid-rail.

CALIBRATION AND SETUP
Vnom and Ima x
Vnom and Ima x make up the rated conditions of the module
(SA9607P’s Kr parameter). Vnom is the module’s rated voltage
and Ima xthe module’s rated current. The PM9607AP module is
designed for rated conditions of 230V/60A. The software
defaults to Vnom = 230V and Ima x= 60A.
Software is available to setup and calibrate the SA9607P
device. Download the SA9607P1.zip file from the SAMES web
site. From the following URL:
http://www.sames.co.za/emsoft/9607-1.zip
LED Constant
LED Constant selects the module’s LED pulse rate (calibration
LED), which is the SA9607P’s CLED parameter. The options
available are 6400 p/kWh or 3200 p/kWh. Entering a ‘0’ will
enable the 1252 pulses/second (at rated conditions) mode for
fast calibration.
The latest version of the evaluation software and source code
is included in the zip file. The software was written with Borland
C++ Ver 3 and should run on any PC with DOS operating
system. The program was written as clear as possible so that it
can easily be modified for specific needs.
Start the program from the DOS prompt with:
c:\>sa9607p 1 1000
Counter Resol.
Counter resolution sets the modules counter resolution
(SA9607P’s CRES parameter). The options are 1,10 or
100p/kWh.
NAVIGATING
Use the cursor keys to move up and down between the
parameters listed under the “SA9607P Meter Parameters”
section. Press Enter on the parameter that needs to be
changed. The options available will be displayed. Type in the
correct option or value and press Enter again. The new setting
will be displayed.
Counter PW
Counter PW set up the mechanical counter’s pulse width
(SA9607P’s CPW parameter). The available options are 71ms
and 142 ms. The PM9607AP module uses an impulse counter
with a pulse width of 71ms.
A detailed description of the parameters listed on the screen
are described in the SA9607P datasheet. The following is a
description of the functionality of the SA9607P Meter
Parameters, displayed on the PC’s screen, figure 7.
Channel1 Err / Channel2 Err
The module may be calibrated by entering the percentage
error in relation to a calibrated meter or Wh-Standard. The
percentage error is calculated as follows:
Error=(Energy from module – Real energy)/Real energy x 100

PCB DESIGN
For module calibration use Channel Sel. (below) to switch to
one of the two channel permanently. Calibrate the channel and
switch to the next channel. Calibrate the channel and set
Channel Sel to automatic for normal meter operation. This is
equal to the SA9607P’s Kc parameter, which is used for
channel balance.
The module represents a Class 1 meter and is designed to
demonstrate the functionality and performance of both the
SA9607M and the SA9607P single phase metering circuits.
The SA9607M requires external settings and gain adjustment.
The SA9607P allows for complete digital calibration without
any external adjustments. The board can be configured for
either of the two ICs by means of jumper settings.
Channel Sel.
The channel select parameter selects the source for energy
metering. (SA9607P’s CS parameter). The options are ‘0’ for
automatic, ‘1’ for channel 1 and ‘2’ for channel 2.
The module is a demonstration unit as well as a reference point
for the meter manufacturer. All the digital pins of the device
have at least one test point. Jumpers isolate LED’s and
counters from the device
Earth Leak
The modules earth leakage compensation value is set up with
this parameter. (SA9607P’s Ne parameter). The options are ‘0’
for a factor of 0.15, ‘1’ for a factor of 0.076 and ‘2’ for a factor of
0.032.
GROUND PLANE
The groundplane, which is connected to neutral, protects the
device from external noise and is used to connect the power
supply bypass capacitors C1 and C2. On the current input
resistors and the CT termination resistor loops are introduced
to cancel out the signal induced by the transformers magnetic
field.
LIST MEMORY
The memory map, as calculated from the settings in the
program, is listed by pressing “l”. It does not show the content
of the EEPROM.
The 5V supply is de-coupled and routed directly to the power
pins of the IC. P2 is connected with a separate track to the VSS
pin of the SA9607.
