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 150 V relative to earth. It must be used indoors in an
environment with level 2 pollution and at an altitude below
2,000 m.
