1. INTRODUCTION
The C.A 8220 is an AC+DC 600 V category III
single phase power analyser (IEC 1010) with a
digital LCD display screen. It is a measurement tool
for effective values, power and electricity distribution
network disturbances, enabling the user to obtain
instant images of the main characteristics of a single
phase network (voltage, current, powers,
voltage/current harmonics, etc.) and to monitor
machines in operation (temperature, current and
duration of launch, resistance of windings, rotation
speed). Compact and shock resistant, its ergonomic
design and easy interface make it user friendly and
intuitive.
The C.A 8220's accuracy is better than 1% (not
including error due to current sensors). It has a
greater flexibility due to its choice of different
sensors for measuring from a few hundred
milliamperes (MN93A) to several kiloamperes
(AmpFLEX).
The C.A 8220 is designed for technicians, company
control and maintenance team engineers, as well as
administrations subscribed to yellow rates (36,kVA
to 250,kVA) and green rates (> 250 kW).
The characteristics of the appliance are detailed on
page 34.

3.5 The rotary switch
Its eight possible positions select the operating
mode of the C.A 8220 (voltage, current, power,
etc.). Details of available modes are given in
chapter 4 on page 9.
3.6 The light indicator
Located in the bottom right hand corner of the
appliance, this light indicator (Figure 1, rep. 7) (LED
orange) is:
Lit when the C.A 8220 is running on the optional
mains power.
Switched off when the C.A 8220 is running on
its internal battery.
3.7 The optical interface
This optical bidirectional connection (Figure 1, rep.
6) has three distinct functions:
Transmits all information and measurements
relating to the current mode from the C.A 8220
to a thermic serial printer.
Transmits all measurement data via specialised
software from the C.A 8220 to a PC,.
Transfers any embedded software updates
available on the Chauvin Arnoux website from a
PC to the C.A 8220.
In the last two cases, the transfer rate is
automatically determined by the C.A 8220, in
compliance with the software used; the maximum
speed reaching 115.2 kbps.
Communication between the CA 8220 and the
PC can be, in certain cases, much improved by
using the USB connection rather than the PC's
RS232 connection.
3.8 The support stand
A retractable support stand (Figure 4, rep. 4), fixed
at the back of the C.A 8220, and maintains the
appliance in a position 30° to horizontal.
3.9 Power
3.9.1 Battery
The electrical power supply for the C.A 8220 is
ensured via six elements (standard batteries or
rechargeable batteries) (Figure 4, rep. 1) in AA
format (LR6 - NEDA 15A). The battery life is
detailed in paragraph 3.9.2.
The elements are accessible, from the back of the
C.A 8220, by turning the lock a quarter turn (rep. 2)
anti-clockwise using a coin (rep. 3).
Figure 4: Accessing the battery elements. 00 3

3.9.2 Battery life
The table below details the battery life, in hours,
depending on the type of battery.
Back-lighting
Type of power supply Without With
AA batteries > 40 hours > 20 hours
NiMH 1800, mAh
accumulators > 30 hours > 16 hours
NiCd 900mAh accumulators > 15 hours > 8 hours
3.9.3 Operating on battery power
The battery life depends on the type of battery used
(see paragraph 3.9.2). As soon as the pre-set
battery voltage threshold is reached, one of the alert
levels is activated:
Level 1: the battery capacity is weak, but the
appliance can still be used. The icon,
located in the bottom left of the screen, flashes
once per second. At the same time, an audible
beep is emitted once.
Level 2: the battery power is low enough to
require the immediate replacement of the
batteries. The icon, located in the bottom left
of the screen, flashes once per second. In
addition, every 10 seconds (and repeated 7
times for a whole minute) a beeping sound is
emitted together with the message
displayed on the screen. After once minute, the
appliance switches itself off.
Figure 5: The low battery indicator signals the need for a
replacement. BATT
3.9.4 Mains operation
When the optional power unit is plugged in, the C.A
8220 uses mains power, without discharging on the
internal battery. The orange light (Figure 1, rep. 7) is
lit. Indeed, the battery does not need to be fitted
when operating on mains power.

4.2 Note on selecting a mode
This note is valid for all the positions of the rotary
switch with the exception of OFF, and .
Any given position of the rotary switch corresponds
to two measurement modes.
Example: in the position, the user can select
either the voltage mode (V), or the current mode
(A).
The mode corresponding to the white symbol is
activated when the rotary switch is positioned on
a function.
Example: the voltage mode is activated when
the switch is turned to the position.
To access a mode corresponding to the yellow
symbol, press the yellow key without changing
the position of the rotary switch. This selection is
indicated in the table opposite by boxes with a
yellow background.
Example: the current mode is activated when the
switch is in the position and after pressing
the yellow key .
To return to a mode with a white symbol, press
the white key ( ).
