CALIBRATION AND SETUP

Software is available to setup and calibrate the SA2007P

device and is supplied with this module.

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 SA2007P datasheet. The following is a

description of the functionality of the SA2007P Meter

Parameters, displayed on the PC’s screen, figure 7.

NAVIGATING

V

max

V

and I

make up the rated conditions of the module

(SA2007P’s Kr parameter). V

is the module’s rated voltage

and Imax the module’s rated current. The PM2007M/PPE

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

nom

software defaults to Vnom = 230V and Imax = 60A.

LED Constant

Counter Resolut.

Counter PW

Channel1 Err / Channel2 Err

LED Constant selects the module’s LED pulse rate (calibration

LED), which is the SA2007P’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

(SA2007P’s CRES parameter). The options are 1,10 or

100p/kWh.

Counter PW set up the mechanical counter’s pulse width

(SA2007P’s CPW parameter). The available options are 71ms

and 142 ms. The PM2007M/PPE 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
