👉 Tachol, also known as a tachograph or an oscilloscope, is a device used for measuring and viewing electrical signals. It consists of a screen that displays the voltage levels across a wire or circuit, which are then converted into a graphical representation on a display screen. When used in conjunction with a computer monitor, such as a TDA-103 oscilloscope, tachol can be used to measure the current and voltage of electrical components in an industrial setting.
