INTRODUCTION
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 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 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
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.

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 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.

USING THE SA9607P IC
The EEPROM on the SA9607AP module may be programmed in circuit with the use of a PC and a IIC interface module. The
interface module is available from SAMES and includes a IIC interface, a 7 way connector cable as well as all the components
needed to convert the module to a trim pot less meter. Figure 2 show how to connect the metering module, interface module as well
as the PC.

Figure 2: PM9607AP mains connections as well as PC programming setup
To use the PM9607AP module with a SA9607P integrated
circuit the following components need to be changed:
n Insert the EEPROM from socket U3.
n Replace termination resistors R16 and R7 with 3.6W
resistor.*
n Remove Channel 2 trim-pot P1.*
n Remove P2 trim-pot. Short-circuit the trim-pot footprint.*
n Replace resistor R17 with a 24K resistor.*
n Remove jumpers J5, J6 and J7.
n Resistor R22 must be fitted if EEPROM will be
programmed in circuit.
* Component change is only require if the module should not
contain any trim-pots.

ISOLATED PC INTERFACE MODULE
OPERATION
The isolator module connects to a standard PC printer port by
means of an extender cable on the one side and to the
PM9607AP on the other side. The PC is completely isolated
form the evaluation module and can be used to program the
EEPROM on the PM9607AP module safely.
The SA9607P is designed to be the bus master and does not
support multi master mode. Resistor R22 is used to overdrive
the clock signal of the SA9607P during programming.
