Universal high-frequency voltmeter V7-83

A small-sized digital magnetometer (gaussmeter, teslameter), a residual magnetization meter ION-3701 version "North" is a modern high-precision device (a variant of the ION-3701 device) and used for a wide range of tasks in areas where it is necessary to determine the magnitude of the magnetic field and residual magnetization in adverse climates, conditions of negative temperatures, the Far North and etc . It is equipped with a three-dimensional magnetic field sensor and has outstanding technical characteristics and extensive functionality.

Mathematical processing of the measurement makes it possible to determine and display on the indicator board the relative systematic change in frequency, the average relative value of the frequency difference, the RMS relative frequency deviation, the RMS relative two-sample frequency deviation.

The voltmeter is capable of working both independently and as part of automated measuring systems with interfaces such as USB, RS-232, IEEE-488 (CPC).
