Chauvin Arnoux®, Inc. d.b.a. AEMC® Instruments
certifies that this instrument has been calibrated
using standards and instruments traceable to
international standards.
We guarantee that at the time of shipping your
instrument has met its published specifications.
An NIST traceable certificate may be requested
at the time of purchase, or obtained by returning
the instrument to our repair and calibration
facility, for a nominal charge.
The recommended calibration interval for this
instrument is 12 months and begins on the date of
receipt by the customer.
Your instrument is equipped with a NiMH battery. This technology offers several
advantages:
• Long battery charge life for a limited volume and weight.
• Possibility of quickly recharging your battery.
• Signicantly reduced memory effect: you can recharge your battery
even if it is not fully discharged.
• Respect for the environment: no pollutant materials such as lead or
cadmium, in compliance with the applicable regulations.
After prolonged storage, the battery may be completely discharged. If so, it must
be completely recharged.
Your instrument may not function during part of this recharging operation.
Full recharging of a completely discharged battery may take several hours.
In this case, at least 5 charge/discharge cycles will be necessary for your
battery to recover 95% of its capacity.
To make the best possible use of your battery and extend its effective service life:
• Only use the charger supplied with your instrument. Use of another
charger may be dangerous.
• Only charge your instrument at temperatures between 0° and 40°C.
• Comply with the conditions of use dened in the operating manual.
• Comply with the storage conditions specied in the operating
manual.
NiMH technology allows a limited number of charge/discharge cycles depending
signicantly on:
• The conditions of use.
• The charging conditions.
Please refer to the user manual for correct replacement of the battery.
Do not dispose of the battery pack with other solid waste. Used batteries
must be entrusted to a qualied recycling company or to a company
specialized in processing hazardous materials.

Precautions and Safety Measures
Read the user manual, supplied on CD-ROM, completely and
comply with the operating precautions before operating this instrument. Non-compliance with the warnings and/or operating instructions might damage the instrument and/or its components and
could prove dangerous for the user.
This instrument has been designed for use:
• indoors
• in an environment with pollution level 2,
• at an altitude of less than 2000 m,
• at a temperature between 0°C and 40°C
• with relative humidity of less than 80% up to 31°C.
The safety of any system integrating the apparatus concerns the
responsibility of the assembler of the system.
It can be used for measurements on circuits 600V CAT III, 1000V
CAT II in relation to earth and can be powered by a 98 to 264V
mains network, with an external power supply. However, some
accessories can lead you to use this instrument on circuits of lower
voltage and category. Conform the given values when connecting
the accessory.
Definition of Measurement Categories
CAT I: CAT I circuits are circuits protected by low level transient over-
voltage limiters.
Example: protected electronic circuits
CAT II: CAT II circuits are household or similar appliance power
circuits, which may carry medium-level transient over-voltage.
Example: household appliance and portable tool power supplies
CAT III: CAT III circuits are high-power appliance power circuits, which
may carry high-level transient over-voltage.
Example: industrial machinery or instrument power supplies
CAT IV: CAT IV circuits are circuits which can carry very substantial
transient over-voltage.
Example: power feeders

Before Use
• Comply with environmental and storage conditions.
• External power supply : it must be connected to the instrument and to
the mains network (from 98 to 264VAC). Make sure that it is in good
working conditions.
During Use
• Read carefully all the notes preceded by the symbol .
• The instrument power supply is equipped with an electronic protection
system which is reset automatically when the fault is eliminated.
• Be sure not to obstruct the ventilation holes.
• As a safety measure, use only suitable cords and accessories supplied
with the instrument or approved by the manufacturer.

CHAPTER 1
GETTING STARTED
1.1 Receiving Your Shipment
Upon receiving your shipment, make sure that the contents are consistent with the packing list. Notify your distributor of any missing items. If
the equipment appears to be damaged, le a claim immediately with the
carrier and notify your distributor at once, giving a detailed description of
any damage. Save the damaged packing container to substantiate your
claim.
1.2 Charging the Battery
IMPORTANT NOTE: When the oscilloscope is delivered, the battery may
be discharged and require a complete recharge. Full charging of the
battery will then take about two and a half hours, with the oscilloscope
switched off.
Once the battery is installed, follow the external power supply start-up
instructions.
• To speed up recharging of the battery, switch off the power to the
oscilloscope with a long press of the ON/OFF button.
• Battery fully discharged: during the rst 10 minutes, the CHARGE LED of the external power supply ashes, indicating that the battery is slow-charging. The CHARGE LED then lights up when it
switches to fast-charging.
During the charging of the battery (after 15 min), powering on of the
oscilloscope causes premature stopping of the charge. It is possible
to restart the charging by disconnecting, then reconnecting the charger.
The LED goes out when the battery is fully charged (approx. 2h30).

1.3 Charging the Battery while using the Oscilloscope
When the oscilloscope is connected to the AC power via the external
power supply, it is possible to perform slow-charging of the battery. The
CHARGE LED of the external power supply lights up. Full recharging of a
totally discharged battery then takes approximately ve and a half hours.
The LED goes out when the battery is fully charged.
Frequently recharging a battery when it is not fully discharged
reduces its life span.
1.4 Powering the Instrument with the Battery
When the oscilloscope is powered by a battery, a charge status indicator
appears in the display area:
the battery is 100% charged
the battery is 80% charged
the battery is 60% charged, etc.
If only one charge bar is present, it means that the battery can
only operate for a few minutes more, so you are advised to
recharge it or switch to the AC power supply.
The battery is totally dead and the screen is about to shut off.
You must either recharge the battery or connect the instrument to the external power supply.
To maintain good condition of the battery, use the oscilloscope until at
least one bar remains before recharging.
1.5 Power Source
The portable oscilloscope is designed to operate on a power source from
98 to 264V (ACrms) at 50 to 60Hz or in stand-alone mode with a battery.
The instrument is delivered with an AC power adapter, an external power
supply (battery charger) and an NiMH battery (9.6V, 3.5A/h).
Type: time delay, 2.5 A, 250 V, 5 x 20 mm
The external power supply is equipped with a protection fuse that must
only be replaced with an identical model.
Replacement must only be performed by qualied personnel.
Contact your distributor or AEMC® for servicing.

1.6 External Power Supply Start Up
• Connect the 4-pin lead of the external power supply to the “DC-Input”
socket located on the side of the oscilloscope.
WARNING: Do not insert any metal objects into this lead.
• Connect the power cord from the external power supply to the power
line.
The POWER LED on the adapter lights up, indicating that it is live.
The CHARGE LED ashes, indicating:
• the absence of the battery or
• slow charging of the battery, if it is present in the oscilloscope.
Press the instrument’s ON button. It lights up and a clock is displayed on
the screen during the start-up sequence. The message “Instrument startup” is displayed. The oscilloscope is then ready for use.
The symbol
in the display area for the current value means
that the instrument is connected to the AC power supply.
NOTE: By default, the “Advanced” mode is not active.
1.7 Turning the instrument ON/OFF
• Power on by a short press.
• Switch the instrument to standby (yellow LED ashing inside the
key) by one short press. A second press on the key reactivates the
instrument.
• Power off by a long press (>3 s): the conguration and les are
saved after approximately 15 s.
WARNING: If the instrument is not equipped with a battery, never disconnect
the instrument from the AC power while the message “System shut down:
Please wait before switch off power” is displayed on the screen. Otherwise,
the current file and all the files previously saved will be lost.
