To perform the tests, components are connected to terminals below the display, and a warning is given about residual voltages on the BNC input terminals as a precaution. It is noted that certain oscilloscope controls, such as intensity and focus, do not affect component testing. This is performed by a winding in the oscilloscope's mains transformer that generates a sinusoidal voltage. This voltage, along with the drop in an internal resistance, allows data about the tested components to be displayed on the screen, based on horizontal and vertical deflection. For example, resistance measurements show a line on the screen whose slope indicates the resistance value, which can be measured between 20 and 4700 ohms. Resistors exhibit equal phases in horizontal and vertical deflection voltages, resulting in a line. In contrast, capacitors and inductors, by creating phase shifts, generate elliptical patterns that reveal impedance. The device can measure capacitors between 100 nanofarads and 1000 microfarads and verify inductance, which resembles a short circuit at 50 hertz.
