Installation AND START-UP
The manual you hold in your hands contains information and warnings that the user should
respect in order to guarantee a proper operation of all the instrument functions and keep its safety
conditions.
If the instrument is not used according to manufacturer’s specifications, the protection of
the instrument can be damaged. Note that with the instrument powered on, cover opening or
elements removal actions may allow accessing dangerous parts. Therefore, before any adjustment, replacement,
maintenance or repairing operation is carried out, the instrument must be disconnected from any power supply
source.
When any protection failure is suspected to exist, the instrument must be
immediately put out of service. Contact then with a qualified service representative.

Starting the analyzer up
Before connecting the instrument to the mains, please consider following points:
5) Supply voltage: 100 V a.c. – 240 V a.c. , 50... 60 Hz.
The instrument must be energized by a supply circuit with protection earth terminal.
6) Maximum input voltage at the voltage measuring circuit:
;500 V a.c. phase-neutral (CAT III)
Use always the voltage leads factory-shipped with the instrument.
7) Burden: 15 VA.
8) Operation conditions:
-Operation temperature: 0 ºC to 40 ºC.
-Operation humidity: 80% for temperatures up to 31ºC decreasing linearly to 50% relative
humidity at 40ºC.
9) Safety : Designed to meet protection category III 600V as per EN 61010.
10) Current measuring range: according to the current clamp used
Current clamps Measuring range
CP-2000-200 clamp 10 to 2000 A a.c. (scale 2000 A)
1 to 200 A a.c. (scale 200 A)
CPR-1000 clamp 5 to 1000 A a.c.
CPR-500 clamp 2,5 to 500 A a.c.
CP-100 (M1-U) clamp 0´5 to 100 A a.c.
CP-5 clamp 25 mA to 5 A a.c.
Flexible clamp Measuring range
C-FLEX 200-2000-20000 100 to 20000 A a.c. (scale 20000 A)
10 to 2000 A a.c. (scale 2000 A)
1 to 200 A a.c. (scale 200 A)
NOTE: It is always advisable to take measurements at the high range of the scale to obtain a better accuracy.
To start measurement works with the analyzer:
11) Connect to the main with the factory-shipped cables. Also connect the protection earth terminal to avoid
possible disturbances over the analyzer.
12) Connect the voltage leads at each phase of the monitored system, as well as the neutral when it exists.
13) Connect the Current clamps at each phase conductor. Each current phase must coincide with its voltage
phase.
14) Respect the connection modes shown at each diagram to correctly achieve powers, PF and energies
readouts.

16
To turn the instrument on:
15) Press the switch <ON> at the analyzer frontal cover. The analyzer introduction screen appears. The user
can now select the operation mode program for the analyzer
16) After some seconds, a screen allowing the choice of the analyzer program to be used is shown up.
17) One the desired program has been selected, analyzer will check the type of ammeter clamps connected to
the analyzer. This process is only performed when analyzer is turn on, and in case that the connected
clamps does not matches with the programmed ones, then the analyzer will automatically give the option
to change the ammeter clamp setting:
-Press <ENTER> to validate the suggested clamp setting. The new transformation ratio
will be set at the ratio detected in the clamp L1.
-Press <ESC> to exit the auto-checking process with no change in the analyzer setup.
18) After some seconds the principal electrical parameters of the network are displayed.
NOTE : If nothing is shown on display, a discharged battery or any problem with the display contrast might
exist.
Initial considerations after the analyzer start-up:
-Format the memory if necessary (see section 0FILES Menu).
-Clear maximum & minimum values as well as energy counters if necessary (see section 0 CLEAR
menu: Deleting data).
-Open a file with the desired name (see section 0 NAME: recording file name). All data will be
automatically saved in this file until a new one is opened. The analyzer internal memory can contain
several files (different analysis).
Warning :
Take into account that when the memory is formatted all previously stored
data is lost. When opening a new file (a different name that the previous one) the
internal memory is not deleted.
When starting new measurements at any installation the meter programming must be checked and modified
if necessary (following steps attached at Section 0 PROGRAMMING THE ANALYZER) Otherwise, the
analyzer will work according the last used program (this is saved in memory even after powering the meter off).
Points to be mainly checked would be:
-Ratio of Current clamps (see section 0)
-Voltage transformer ratio (see section 0)
-Recording period (see section 0)

17
Loading a new program
The analyzer has an internal memory to save diverse operation mode
programs to be used by the user.
Before starting this action, check that analyzer is supplied through the power
supplier set.
To load any program, follow these instructions precisely:
Turn the meter off.
It is necessary to load a coprocessor that comes in a cartridge to part, and
that must settle only in the position of the coprocessor (the last position of
the list)
Connect the cartridge into the appropriate input placed in the power
supplier set.
Turn the meter on.
Select with the keys [5]& [6]that you want to perform a program loading
action (LOAD PROGRAM). Press [ENTER] or wait for a while to confirm
this operation.
Select the position to save the program into.
The analyzer will perform a test to check that the cartridge has been
properly connected.
If an inserted cartridge is detected, then the program will be loaded.
Once the loading is completed, reset the meter.
If no cartridge was found or a loading mistake occurred, reset the meter
and redo the above steps.
A cartridge will be only valid for the analyzer, which the
program was for the first time loaded into.
Note on the cartridge the serial number of its related
analyzer.

18
Turn the analyzer off
To turn the analyzer off proceed as follows:
If no password is set (Default option):
-Press the key [OFF] during 5 s
If a password is set:
-Press the key [OFF] during 5 s
-You will see in display: PASSWORD
-Enter the set password or, if this has not been previously modified, the default password
[3] [SET] [5] [SET].
-Press again the key [OFF]. (In case of a correct password, the analyzer will turn off).
Back-light
To turn the display backlight on/off just make a quick press on the key [OFF].
Choice of the working program
The analyzer can hold in memory different operation mode programs. The choice of the program to be
used is done when starting the meter up.
Turn the analyzer on.
A list of available programs will be shown on display.
Use keys [5]& [6]for the choice of the desired program.
Press [ENTER] or wait for a while to confirm this operation.
CHECK THE SETUP !!!!
All the programs have an independent disposition, therefore, the disposition
will be due to always verify, to assure an appropriate operation.
For instance, if the setup is modified at the “ANALYZER” program, these
modification will not be valid for the “HARMONIC” program, and so for any program.

19
Recharging the analyzer battery
The analyzer is equipped with an intelligent energy charging system. This
means that the instrument continuously checks in an automatic way the state of the
battery, thus the charging process stops when the battery is at its maximum charge
level. The span life of the battery is so increased.
To enable the battery charging proceed as follows:
Connect the power supplier set to the main.
Connect the analyzer to the power supplier set.
Turn the analyzer on by pressing button [ON].
Provided the analyzer is connected to the main through the power supplier set,
the battery is self-recharging.
If the battery is exhausted, the charging process should last at least 3 hours
with no interruption; although a charging period of 16 hours is advisable in order to
completely charge the battery.
The analyzer shows on screen a battery charge indicator:
NOTE: The battery charge is only used while the ANALYZER is turn on.
Energy saving
The ANALYZER has an energy saving system. So, if no key is pressed for at
least 5 minutes, the display is automatically off. The analyzer continues the recording
data process but nothing appears on display.
The display will automatically be active when any key is pressed (excepts for the key [ON] that causes
no effect).

20
DATA VISUALIZATION ON DISPLAY
All measured instantaneous values, as well as maximum and minimum, can
be read on a 160 x 160 pixel, liquid, crystal display (back-light ability).
An indication of the type of data being displayed is shown at the upper right
