User manual

knowledge permits you to independently determine whether individual components
are defective or how to install them in circuits correctly.
This learning package conveys all the basics needed for successful work with the
multimeter.
Components - Basics
The Battery
The battery must be connected in the right polarity to every circuit. The
required battery blot has one red connection wire to mark the plus pole and a
black one to mark the minus pole each. Both wires must be connected to the
experimentation board according to the polarity required.

Resistors
Resistors are among the simplest electronic components. They are labelled in a
colour code of three rings that is read from the edge to the centre. A fourth
ring a little offset from the others indicates the component tolerance. The
colour code is read from the ring closer to the edge of the resistor. The first
two rings represent two digits, the third the multiplier of the impedance value
in Ohm. A fourth ring indicates the tolerance. The impedance value is indicated
in Ohm [Ω].

Figure 3: A resistor with the colour rings yellow, violet, brown and gold has
the value 470 Ohm at a tolerance of 5%.
Figure 4: The resistor
The learning package includes resistors of the following values:
330 Ohm Orange, orange, brown
1 kOhm Brown, black, red
2.2 MOhm Red, red, green

The Ceramics Capacitator
The capacitator is another elementary electronics component. It is available in
two versions. The simpler version is the small, round and flat ceramics
capacitator. It is protected against polarity reversal. Capacities are indicated
in Farad. The ceramics capacitator is labelled with a number code. "104" means
"10 times 10 to the power of 4“, i.e. 100,000 pF (Picofarad).
