You have just obtained a resistance, capacity or inductance
decade box, and we thank you for your trust in us.
To obtain the best service from your unit:
read these operating instructions carefully,
comply with the precautions for use.
1 GENERAL INSTRUCTIONS
If the device is used in a manner unspecified in these
instructions, the protection provided by the device may be
compromised.
1.1 UNPACKING – PACKING
All instruments are checked mechanically and electronically
before shipment. All precautions are taken to be sure you
receive an undamaged instrument. If there is damage, notify the
carrier immediately.
1.2 PRECAUTIONS AND USAGE SAFETY
1.2.1 Before any use
Resistance, condenser and inductance decade boxes are
passive elements to be inserted into trial or development
circuits to obtain the desired resistance, capacity or inductance
values by a combination of decades.
These decade boxes are compliant with safety standard IEC
61010 – 1.
For your own safety and to prevent any damage to your
equipment, you must follow the instructions in this manual.
This equipment can be used in category II electrical circuits not
exceeding 150V relative to earth. It must be used indoors in an
environment with level 2 pollution and at an altitude below
2,000m.
Definition of Installation Categories (see IEC 61010-1)
CAT I: Circuits not directly connected to network and
specially protected.
Example: protected electronic circuits.
CAT II: Circuits connected directly to low-voltage
installation.
Example: power supply for domestic electrical appliances
and portable tools.
CAT III: Power supply circuits in the building installation.
Example: Electrical panel, circuit breakers, fixed industrial
machines or devices.
CAT IV: Source circuits of building low-voltage installation.
Example: Power feeders, counters and protection systems.

14 BR04-05-06-07 – BC05 – BL07
For safety reasons, you must use only measuring leads, of
voltage and category at least equal to those of the instrument
and compliant with standard
IEC 61010.
Do not use damaged equipment.
Before use, always check all the cord insulation.
1.2.2 Meaning of symbols used:

Earth.
The CE marking indicates
conformity with European
directives, in particular LVD
and EMC.
The rubbish bin with a line
through it indicates that, in
the European Union, the
product must undergo
selective disposal in
compl
iance with Directive
WEEE 2002/96/EC. This
equipment must not be
treated as household waste.
1.2.3 When using the equipment
To prevent electrical discharge, injury or damage to the device,
and to ensure you use the decade box without risk, follow the
safety recommendations below:
•Read the operating instructions fully before using this
device and observe all safety instructions.
•This device must be used indoors, up to 2,000m altitude.
•Always connect the box's earth terminal to an earth
protection.
•Never exceed the protection limit values indicated in the
specifications for each type of decade.
•When the decade box is inserted into a circuit, do not touch
the unused cords or terminals.
•Every time, after use, disconnect the supplies for the
capacity boxes and discharge the condensers.
•Avoid working alone.
•Use the device only as specified in this manual; otherwise,
the protection provided by this equipment may be altered.
•Do not use this device if it appears damaged.
•Inspect the integrity of lead insulation. Replace damaged
leads.
•Be careful when working with voltages higher than 70Vdc
or 33Vrms and 46.7Vpp, such voltages can pose a risk of
electrocution. Depending on conditions, the use of
individual protection is recommended.
•Before opening the equipment, disconnect it from all
circuits and cords.

After a long period of storage, it may be worth turning each of
the decade's switches before use.
Like all measuring or testing devices, regular metrological
verification is necessary.
To have your devices checked and calibrated, please contact
our Cofrac approved metrology laboratories or Manumesure
centres.
