1.- INTRODUCTION.
The C-80 analyzer is a programmable, measuring instrument that measures,
calculates and records in the memory the main electrical parameters in single phase or
balanced three phase with neutral, industrial systems. It is a small, portable and light
instrument that measures in true RMS.
The equipment has been manufactured with the latest technology and is the most
advanced means of measuring and recording electrical parameters on the market.
The C-80 analyzer allows automatic recording with a programmed time, and also,
instantly (or simultaneously) records data in the internal memory at regular time intervals.
This manual assists in the installation and use of C-80 type measuring instruments
and helps to obtain the best service from it. Carefully read this manual before connecting
the equipment to avoid incorrect use which may cause irrevocable damage.
For the safe use of the C-80 it is vital that those persons
installing it or handling it follow the usual safety procedures as well as
the individual warnings in this instruction manual, as well as the
different warnings it contains.
If the equipment is used in a way not specified by the
manufacturer, the equipment's protection may be compromised.

-------------- SYSTEM ANALYZER C-80 ----------- Page no. 5
3.- CONNECTION AND START-UP
Before connecting the equipment, check the following:
a) Frequency: 45...65 Hz.
b) Maximum voltage in the measurement circuit:
;500 V AC. between voltage inputs.
c) Maximum measurable current: according to clamps used.
d) Whenever a clamp is connected, the C-80 auto-detects the clamp and stores the
configuration (Current primary) of the clamp automatically in the setup. This does
not occur with the CP-5 clamp. This is due an external transformer that has to
manually programmed.
If the clamp detected has 2 scales (CP-2000-200) or three scales (C-FLEX), the
equipment goes into setup mode and the scale may be changed with the cursors
[▼][▲]and then entered with the [ENTER] key.
Ammeter clamps Measurement range
CP-2000-200 20 to 2000 A AC. (2000 A range)
2 to 200 A AC. (200 A range)
CPR-1000 10 to 1000 A AC.
CPR-500 5 to 500 A AC.
CP-100 (M1-U) 1 to 100 A AC.
CP-5 50 mA to 5 A AC.
CF-5 (Leaks) 10 mA to 5 A AC.

NOTES:
- For better accuracy it is advised to always measure the highest part of the scale.
- When a new clamp is connected, if the scale programmed is different from the
previous one, maximum/minimum, registers and energy counters will be erased
from the memory.
When a new clamp is connected, if the scale programmed is the same that the
previous one, only maximum/minimum be erased from the memory.

This manual has information and warnings that the user must follow to ensure
the safe operation of the equipment and to maintain it in good condition in
terms of safety.
If the equipment is used in a way not specified by the manufacturer, the
equipment's protection may be compromised. Bear in mind that when the
equipment is connected, opening the covers or removing parts may access
dangerous parts.
If it is likely that there has been a loss in protection (for example if there are
visible signs of damage) the equipment must not be handled. In this event
please contact a qualified service representative.

- Unbalanced three phase with neutral connection:
The C-80 can take measurements of an unbalanced three phase with neutral system.
To do this, measurements will have to be taken in each of the three phases separately, as
though a single phase system was being measured:
1. V1-N / I1
2. V2-N / I2
3. V3-N / I3
The C-80 will measure values per phase. If the total power (W or var) is required the
measured powers the measured powers have the measured powers have to be added P1 +
P2 + P3.
To calculate the kvar(L) of an unbalanced system with neutral, the phase with the
highest inductive load has to be found and then multiply that by three to find the suitable
capacitor bank value.

3.4.- Starting measuring with the C-80
1. To power the equipment connect 2 x 1.5 V DC batteries (LR6, type AA). The lower
cover on the rear of the equipment has to be removed and the batteries inserted
into the correct slot (check the polarity).
NOTE: Whilst doing this, the equipment has to be disconnected from the power
supply.
2. Attach the voltage terminals to each system phase that is to be measured. Point
3.2 Connection diagrams.
NOTE: The user must change between single phase mode or three phase mode
by giving a short press on the II/III button, depending on the type of
installation.
3. Attach the correct current clamp on phase 3 (balanced three phase) or on phase 1
(single phase).
4. Keep to the connections shown in the diagrams to obtain power readings, P.F. and
correct form of energies.
To start up the equipment:
5. Press the [ON/OFF] switch on the front of the analyzer. After starting the C-80
software version appears on the display.
6. At this point, the C-80 will detect the clamp connected. This process of self
detection is done when a new clamp is connected. (See point 3 Connection and
start-up).
7. After a few seconds the main system parameters will appear on the display.
When starting measurements in a particular installation the equipment settings have
to be checked and if necessary changed (following the instructions in section 4 Programming
and displaying parameters). If this is not done, it may mean that the measurements are not
correct.
The C-80 Analyzer has an energy saving system. If no key is touched for 5 minutes,
the C-80 switches itself off. This does not occur if the equipment is recording.
To switch off the equipment, the [ON/OFF] button has to be pressed.

-------------- SYSTEM ANALYZER C-80 ----------- Page no. 20
4.6.- Registering menu
The registering menu shows screens identical to those in the measurement menu
with the exception that there is a start screen showing date and time of registering.
When the equipment enters the registering menu it stops registering, if it is so doing.
On returning to the measurement menu, the registering is NOT restarted until it is “tripped”
by the [ENTER] key.
If no register has been made or all registers have been deleted from the memory, on
entering the registering menu, the words <NO File> appear on the screen. (To register, see
points 4.6.1 and 4.6.2.)
To access the Registering menu press the [REG] key for a while from the
Measurement menu. The screen will show [Reg In] (with recording in the memory).
To exit the SETUP menu press once again the [SETUP] key for a while. The screen
will show [Reg Out]. Return to the measurement screen from which it was accessed.
Once in the registering menu, the following keys are used:
REG key:
Exit the register menu and return to the measurement menu. Return to the
measurement screen from which it was accessed.
ENTER key:
Pressing the enter key allows the registering to be advanced. This is shown by the
RAPID FLASHING of the REG icon. The first screen is the clock and by repeatedly
pressing the [ENTER] key the required register is displayed.
CURSOR keys:
In monitor mode, the [▼] and [▲]keys allow the 8 registering screens to be browsed.
MAX-MIN keys:
With the MAX/MIN keys the maximum and minimum values of the variables are
shown for 3 seconds.
When no maximum and minimum are displayed this is shown by BLANK SPACES
The C-80 ANALYZER has the option to record the measurements and store them in a
non- volatile rotating memory with a capacity of up to 33 recordings. The C-80 has an option
to register up to 33 measurements and store them in the non-volatile rotating memory. It has
a rotating file, meaning that once the 33 recordings are full it will continue registering new
data in the oldest position.
The registers may be done automatically and timed or can be done instantaneously
by pressing the [ENTER]. The two methods can be simultaneous.
