Calibrators universal H4-57 are designed for verification and calibration of measuring instruments of electrical quantities, electronic (digital or analogue) measuring devices. The device consists of two units: - the main, basic unit and amplification unit to expand the range of reproducible voltages and currents under the control of the calibrator.
The delivery set of the device can include a current coil KTI-1000/34, designed to expand the range of reproducible current up to 1000A. The device provides: reproduction of direct and alternating (sinusoidal) current voltage; reproduction of direct and alternating (sinusoidal) current strength; reproduction of alternating voltage and current frequency; reproduction of resistance to direct and alternating current.
