AOIP S.A.S guarantees the absence of faulty materials and the manufacture of this product under normal
conditions of use and maintenance. The guarantee period is one year and takes effect on the date of delivery.
Parts, repairs to the product and service are guaranteed for a period of 90 days. This guarantee only applies
to the original purchaser or the end user if he is a client of an AOIP S.A.S approved distributor and does not
cover fuses, interchangeable batteries/cells nor any product which, in the opinion of AOIP S.A.S, has been
badly handled, modified, neglected or damaged by accident or subjected to abnormal conditions of use or
handling. AOIP S.A.S guarantees that the software will function largely in accordance with its functional
specifications for a period of 90 days and that it has been correctly recorded on non-defective media. AOIP
S.A.S does not guarantee that the software contains no errors or that it will operate without interruption.
AOIP S.A.S approved distributors shall apply this guarantee to products sold to new clients it has not served,
but are not authorized to offer a longer or different guarantee in the name of AOIP S.A.S. Guarantee support
is offered if the product was purchased by an intermediary from an AOIP S.A.S approved point of sale or if the
purchaser has paid the applicable international price. AOIP S.A.S reserves the right to invoice the purchaser
for the costs of importing, repair or replacement parts if the product purchased in one country was sent to
another country for repair.
The obligations under the guarantee of AOIP S.A.S are limited at the discretion of AOIP S.A.S, to

Introduction A
NTA47209-100A7 7 / 35
A. GENERAL
Thank you for choosing this AOIP SAS precision measuring instrument, which incorporates our extensive experience in
the manufacture of precision measuring appliances, which spans over more than a century.
We are thus able to continue our policy of constant innovation which has served our customers so well for more than 100
years. AOIP S.A.S welcomes any comments or suggestions you might have to enable us to perfect our know-how and
make our future products even better.
A.1 Introduction
The CP6632 is a hand-held process calibrator. It is more particularly intended for calibration and maintenance. It can
measure and generate electrical quantities either on site or in the laboratory. It fulfils voltage and current measuring and
generation functions (DC or LF ramp signals) and a continuity test (on passive loop).
Owing to its monitoring (regulation) mechanism in transmission mode, the instrument cannot take measurements and
transmit simultaneously.
The CP6632 features numerous associated functions that extend its range of applications:
Display of results in accordance with a linear conversion law or not.
Generation of increments, single or cyclic ramp signals.
Its utilisation is facilitated by a series of improvements:
Fast access to all the functions.
Intuitive user interface.
Graphic display of 160x160 pixels
Connection by 4-mm safety sockets.
Powered by 4 AA batteries or a rechargeable battery pack with fast internal charger (Option).
The instrument is enclosed in an ABS casing with an elastomer sheath.

A.3 Safety
A.3.1 Conformity with safety standards
The instrument complies with the directives in effect concerning both electrical safety (2006/95/CE) and electromagnetic
compatibility of electrical measuring equipment (2004/108/CE).
This user's manual contains information and warnings that must be adhered to in order to protect the user against the
hazards of electric current, ensure safe operation of the appliance, and protect it against incorrect manipulations that could
damage it or be detrimental to its safety of use.
A.3.2 Climatic conditions
Per publication CEI 359: operating category I.
Standards application altitude: from 0 to 2 200 m.
Reference conditions: 23°C ±5°C, relative humidity: 45% to 75%.
Nominal operating conditions: -10°C to +50°C, relative humidity: 20% to 80% non-condensing.
Extreme operating conditions: -15°C to +55°C, relative humidity: 10% to 80% (70% at 55°C).
Extreme storage and transport conditions: -30°C to +60°C (without AA batteries or rechargeable battery pack).
A.3.3 Disposal of instrument at end of life
When the instrument reaches the end of its life we recommend that you dispose of it using the specialized waste disposal
channels available in your region, and not the ordinary waste collection service, as the instrument contains elements that
are environmental pollutants. Failing this, you can return the instrument to our company which will dispose of it free of
charge.
A.3.3.1 Waste produced by the instrument
List of classified waste materials:
16.02.14: Waste from electronic equipment:
Electronic boards incorporated in the instrument.
16.06.02: Cells and batteries (dangerous)
Alkaline batteries
3 V lithium battery (CR1225 type).
Or Ni-MH batteries (If the unit is equipped with an AN 6011 battery pack)
15.01.02: Packaging
Instrument casing in ABS plastic.
Elastomer protective sheath.
A.3.3.2 Instrument destruction procedure
To open the instrument: remove the battery compartment cover screw, and the 5 screws fastening the 2 half-shells.
Separate the 2 half-shells. Remove the electronic board from the top shell.
The batteries are housed in the battery compartment (see putting into service chapter).
With the battery pack option, there are 2 polluting elements: the NI-MH (Nickel-Metal Hybrid) batteries and an electronic
board. Separate the 2 elements.
A.3.4 Instructions
The instrument has been designed to function in complete safety if the instructions given in the accompanying documents
are applied. Use of the instrument in any other way can reduce operator safety, and is therefore dangerous and prohibited.
A.3.5 Taking measurements
The measuring leads and wires must be in good condition and be replaced if their insulation seems defective (insulation
cut, burnt, etc.).
When the instrument is connected to the measuring circuits the terminals can be dangerous, therefore do not place your
hands near a terminal, whether used or not.
Never exceed the protection limit values indicated in the specifications.

Safety A
NTA47209-100A7 9 / 35
When the order of size of the measured value is not known, ensure that the starting measurement range is has high as
possible, or select automatic range change mode.
Before changing function, disconnect the measuring wires from the external circuit. Remember that when taking even low
current and/or voltage measurements, that the circuits can carry voltages which, with respect to earth, are hazardous for
the operator.
Never take measurements when the instrument is connected to another appliance by the USB link or when charging the
batteries (option)
A.3.6 Faults and abnormal stresses
Whenever the level of protection of the instrument is believed to be degraded, remove it from service and ensure it cannot
be put back into service accidentally.
The protection might have been degraded if, for example:
The instrument displays visible damage.
The instrument is no longer capable of taking precise measurements.
The instrument has been stored in unfavourable conditions.
The instrument has suffered severe stresses during transport.
A.3.7 Definitions
A.3.7.1 Definition of category and pollution level
CAT II 60V:
The notion of categories determines the maximum transient voltage that can be applied to the measurement inputs (it is
also called overvoltage category). For the CP6632, the maximum permissible overvoltage is 60V (DC or AC)
POL 2:
The notion of pollution determines the isolation distance between the circuits. Level 2 allows temporary conductivity
caused by condensation.

A.4 Maintenance
The instrument must always be reassembled in accordance with the instructions given in this manual. Incomplete or
incorrect assembly can jeopardize operator safety.
The authority in charge must check regularly that the safety components have not altered over time and perform all the
necessary preventive maintenance operations.
Before opening the instrument for maintenance work, always ensure that all the wires have been disconnected from it.
Work (adjustment, servicing, repair) on the open instrument must be avoided insofar as possible, but if such work is
absolutely necessary, it must be performed by qualified personnel that is well aware of the risks involved.
