CALIBRATION AND SETUP

Software is available to setup and calibrate the SA9607P

device. Download the SA9607P1.zip file from the SAMES web

site. From the following URL:

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:

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.

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.

V

and I

make up the rated conditions of the module

(SA9607P’s Kr parameter). V is the module’s rated voltage

and I the module’s rated current. The PM9607AP module is

designed for rated conditions of 230V/60A. The software

defaults to V = 230V and I = 60A.

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.

Counter resolution sets the modules counter resolution

(SA9607P’s CRES parameter). The options are 1,10 or

100p/kWh.

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.

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
