How to use electronic laboratory tools

In the field of electronics, precision in any type of measurement is very important for the correct operation of the circuit. To achieve this accuracy it is very important to know how to use some measuring tools. Today we will explain how to use the basic tools of analogue electronics.

Transformer

Raises or lowers the voltage of a current. They usually have two positive poles and one negative pole. It is widely used in conventional power grids to reduce the voltage of large high-voltage pylons.

Transformer

One thing we must always bear in mind in their use is that incorporates two or three fuses, which tend to blow very easily. and lead to subsequent measurement errors.

Signal generator

Signal generator

Serves to generate signals in the circuit. Normally it can generate three types of waves: square, sine and triangular. It also allows you to select the amplitude and frequency of the generated waves. It is useful to connect it to the oscilloscope to check that what we are doing is correct.

Polimeter

Polimeter

It incorporates a central wheel that allows the function of the device to be varied. Its main function is make measurements in any part of the circuit. Allows to measure:

- Direct current.

- Alternating current.

- Voltage.

- Resilience.

- Continuity (this function is selected by turning the wheel to a sound symbol, when there is continuity between the multimeter terminals a beep will sound).

The multimeter will have to be calibrated depending on component values.

Oscilloscope

It serves to analyse the signals passing through the circuit and the effect of each component on them. All oscilloscopes have two different channels that allow two signals to be measured at the same time.

Oscilloscope

The most complicated thing is to calibrate the apparatus to see the waveform completely. This is done using the function's X-axis (time) and Y-axis (voltage) scaling controls. The calibration will depend on the voltage across the circuit at that time.
