пробник__

This enterprise, probnik__, is a universal tester for various electrical parameters. Its description is missing, but according to available information, it can be used in various forms such as a small probe or even a bracelet. The probe generates rectangular impulses (meander) and measures their frequency on a scale, similar to a frequency meter. A notable feature is that it can operate in a generator mode, where it forms impulses and measures their frequency. The probe can measure voltage in the range of 12 V to 380 V and has a maximum contact resistance of 12 ohms. It is also a miniaturized oscilloscope that can control signals based on their amplitude of 1-320 V, frequency up to 50 kHz, and signal shape from 1.14 to 8. The probe is available in passive form with standard interfaces.
