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.

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

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.

This measures the values relative to a motor start
(maximum half-cycle current effective value,
maximum absolute instantaneous current value,
duration of start) and determines the order of phase
rotation.
Figure 28: The rotary switch in position. 11
4.7.1 Inrush mode (motor start)
This mode requires the C.A 8220 to be pre-
configured. Refer to paragraphs 4.10.1 and
4.10.2 and on page 18. The cables (voltage and
current) can be connected either in single-phase
or balanced three-phase mode.
During steps 2, 3 and 4, it is possible to go back
to the first step (step 1/4) by pressing the
key.

4.7.1.1 Step 1/4
As soon as the appliance is switched to this mode,
the display indicates that the C.A. 8220 is ready.
Pressing the key accesses step 2/4.
Figure 29: The C.A. 8220 is ready. IR01
The symbol means ready.
4.7.1.2 Step 2/4
Figure 30: The C.A. 8220 waits until the starting current
trigger threshold is exceeded. IR02
The symbol means measuring
(measurement in progress).
The motor to be monitored is thus switched on. The
C.A 8220 waits until the effective half-cycle current
exceeds the current threshold for the parametered
motor start (adjustment of this threshold in § 4.10.1,
on page 18). The effective current calculated over a
second is continuously displayed (rep.1). The
appliance automatically moves to step 3/4.
4.7.1.3 Step 3/4
As soon as the motor starting threshold is reached,
the stopwatch is started (see Figure 31).
Once the motor to be monitored is running, the C.A
8220 waits until the effective half-cycle current goes
below the current set threshold (end of start
threshold) (see adjustment in § 4.10.2, on page 18).
The effective current calculated over a second is
continuously displayed (rep. 1). The appliance
automatically moves to step 4/4.
Figure 31: The stopwatch (bottom of the screen) is active
until the low current threshold has been reached. IR03
4.7.1.4 Step 4/4
As soon as the end of motor starting threshold has
been reached, the results are displayed.
Figure 32: Example of results display. IR04
The information is read as follows:
Rep. Measurement
1. Effective maximum half-cycle value of starting
current.
2. Absolute instantaneous value of starting current.
3. Duration in seconds of motor starting.
4.7.2 Phase rotation mode
The mode enables the user to determine the order
of the phases of a three-phase network using the
method known as "2 wire".
The activation of the balanced three-phase
mode has no effect on determining the order of
the phases ( can be or ). The most
important point is to respect the voltage
connections as directed in 1 and 3.
4.7.2.1 Step 1/4
As soon as the appliance is switched to this mode,
the display indicates that the C.A. 8220 is ready
(see following page).

measurement to determine the order of the phases. RO1
Once the test leads are connected to the supposed
L1 and L2 phases, pressing the key moves the
appliance to step 2/4.
4.7.2.2 Step 2/4
The message is displayed for a very short
interval (see image below).
Figure 34: The C.A. 8220 displays this screen for a very
short time. RO02
One of the screens described in the next paragraph
is then displayed.
4.7.2.3 Step 3/4
Two cases are possible:
The display indicates (Error): an error has
been detected during the determination of the
order of the phases. This error may be due to
one of the following causes:
- The three-phase network frequency is
unstable.
- The three-phase network frequency is
outside the 40 Hz to 70 Hz range.
- The voltage signal is too weak (below 10
VRMS).
- Operations were incorrectly carried out.
It is then possible to come back to the first step
(step1/4) by pressing the key.
The display screen shows the following screen.
Figure 35: The C.A. 8220 is ready for the second
measurement to determine the order of the phases. RO03
The user should then connect the L3 phase to the
input (+) of the appliance, within 10 seconds, after
which time the following error message
(time limit exceeded) is displayed inviting the user to
start the sequence again from the beginning (step
1/4).
As soon as the test leads are connected to the
circuit, the C.A 8220 automatically moves to step
4/4.
4.7.2.4 Step 4/4
Three cases are possible:
Case n° 1: a direct order of phases has been
determined. The following screen is displayed:
Figure 36: Direct order of phases. RO4
Case n° 2: an indirect order of phases has been
determined. The following screen is displayed:
Figure 37: Indirect order of phases. RO5

17
Case n° 3: indicates that an error has
occurred during the determination of the order of
phases. This error may be due to one of the
following causes:
- Unstable three-phase network frequency.
- Three-phase network frequency is outside
the 40 Hz to 70 Hz range.
- The voltage signal is too weak (below 10
VRMS).
- Operations were incorrectly carried out.
It is then possible to come back to the first step
(step1/4) by pressing the key.
4.8 position (rotation speed mode)
This mode requires the C.A 8220 to be pre-
configured. Refer to paragraphs 4.10.5 and
4.10.6 and on page 19.
In this position, the C.A 8220 measures the rotation
speed of a turning element.
The tachometer signal should be inputted into
the voltage (+) and (COM) terminals of the C.A
8220. The appliance thus measures the interval
of time between each signal pulse (event) and
subtracts the rotation speed in revolutions per
minute.
Figure 38: The rotary switch in position. 12
Figure 39: Example of a rotation speed measurement. RPM
4.9 position
In this position, the C.A 8220 measures the
temperature (using an external probe not provided)
or the resistance of an electrical circuit.
Figure 40: The rotary switch in position. 13
4.9.1 Temperature mode
The C.A 8220 displays the temperature measured
using a 100 platinum probe (not provided),
connected to the (+) and (COM) terminals of the C.A
8220. The measurement is displayed
simultaneously in degrees Celsius (°C) and degrees
Fahrenheit (°F).
Figure 41: Example of a temperature measurement. TEMP
4.9.2 Resistance mode
Two automatic calibrations are available:
0 Ωto 400 Ω: above 20 Ω(by default) a beeping
sound is emitted.
400 Ωto 2000 Ω.
Figure 42: Example of a resistance measurement. RES

4.10 position (configuration mode)
This position is designed for configuring the
parameters used by the C.A 8220. Once the
configuration has been saved in the non-volatile
memory, it can be accessed even after the
appliance is shut down including during a battery
change.
Figure 43: The rotary switch in . position 14
4.10.1 parameter
The symbol means start.
This parameter is used to configure the Inrush ( )
mode.
Figure 44: Display of parameter relating to the initial
current. Set1
The parameter sets the effective half-cycle
current value serving as the motor start threshold.
When the motor starting current reaches or exceeds
this threshold, the C.A 8220 will count the time
during which the effective half-cycle current value is
strictly in excess of the effective half-cycle end value
(see Figure 31, on page 15).
The value is set using the white and yellow
() keys. The minimum and maximum
terminals are 0 and 5,999 A.
4.10.2 parameter
The symbol means hysteresis.
This parameter is used to configure the Inrush ( )
mode.
Figure 45: Display of parameter relating to hysteresis. Set2
The parameter sets the effective half-cycle
current value serving as the end of motor start
threshold. As soon as the motor starting current is
over or equal to the effective half-cycle current end
(stop) value, the C.A 8220 will stop counting the
starting time (see Figure 32, on page 15 ).
The value is set using the white and yellow
() keys. The preset values are 0, 1, 2, 5
and 10 %.
The effective half-cycle stopping value is
calculated using the following formula.
[effective half-cycle stopping value] = [effective
half-cycle starting value] × (100 – [hysteresis]) ÷
100.
4.10.3 parameter
The symbol means primary. This screen is
only displayed if the C.A 8220 is connected to a
5 A adapter or to the MN93A 5 A clamp.
For all of the other sensors, listed below, which
do not require any adjustment, this screen is not
displayed:
- MN93 200 A clamp.
- MN93A 100 A clamp.
- C193 1000 A clamp.
- PAC93 1000 A clamp.
- AmpFLEX A193 3000 A.
This parameter configures the primary current of the
transformation ratio ( ).
Figure 46: Display of parameter relating to the effective
primary current of the intensity transformer. Set3

19
The parameter defines the value of the primary
effective current of the intensity transformer (IT) or
current transformer (CT) for the MN93A clamp (5 A
calibre) or the 5 A adapter.
The value is configured using the white and yellow
() keys. The minimum and maximum
terminals are 0 and 2,999 A.
4.10.4 parameter
The symbol means secondary.
See the comment in paragraph 4.10.3 -
parameter below.
This parameter configures the secondary current of
the transformation ratio ( ).
Figure 47: Display of parameter relating to the effective
secondary current of the intensity transformer. Set4
The parameter defines the value of the
secondary effective current of the intensity
transformer (IT) or current transformer (CT) for the
MN93A clamp (5 A calibre) or the 5 A adapter. The
value is configured using the white and yellow
() keys. The preset values are 1 and 5 A.
4.10.5 Parameter
The symbol means event per rotation.
This parameter is designed to configure the rotation
speed mode ( ).
Figure 48: Display of parameter relating to the number of
events per rotation of the tachometer signal. Set5
The parameter defines the number of events
per rotation for the measurement of rotation speed
for a machine in operation. If, for example, a
tachometer signal provides two pulses per
revolutions, this parameter will be set to 2.
The value is configured using the white and yellow
() keys. The minimum and maximum
terminals are 1 and 99.
The maximum rotation speed is defined by the
following formula: 120000 / .
4.10.6 parameter
The symbol means threshold.
This parameter is designed to configure the rotation
speed mode ( ).
Figure 49: Display of parameter relating to the threshold
voltage of the tachometer sensor. Se6
The parameter defines the threshold voltage
value used to detect an event (pulse on the
tachometer signal).
Since the signal received by the C.A 8220 can be
unipolar or bipolar, two types of threshold (0.3 and
1.1 V) can be selected. The recommended selection
is as follows:
bipolar signals: 0.3 V threshold.
unipolar signals: 1.1 V threshold.
In both cases, the hysteresis is 0.2 V. The value is
selected using the white and yellow ( )
keys. The figure on the following page gives the
graphs for this hysteresis.
