Product description

Uses and features
1. The HG5520 multifunctional standard source (hereinafter referred to as the standard source) is a meter source integrated with a five-and-a-half-digit LCD backlight (320*240) screen digital display output value, and can display the error of the tested meter, error correction value, Set parameters and items such as the limit value of the meter under inspection, the detection amount of the meter under inspection, step adjustment amount, frequency, gear, and test status prompts. AC and DC voltage and current standard sources with good human-machine dialogue. It is also equipped with a 10Ω~10MΩ digital synthetic resistance generator to facilitate calibration of resistance meters and multimeter resistance levels. Equipped with RS232 interface to realize automatic data processing and two-way communication functions.
2. The standard source is based on a single-chip microcomputer and adopts advanced technologies such as digital technology, large-loop amplitude stabilization tracking, true effective value conversion, high-power power amplifier, and automatic protection closed-case self-calibration. It has the characteristics of good stability, high accuracy, excellent linearity, wide measuring range, safety and reliability, strong applicability, etc. The output amplitude adjustment is equipped with three adjustment combinations of digital keys, encoder and divided step type, making it The control is flexible and the response speed meets the different needs of continuous and fixed value output. The operation is more convenient and practical. It is an updated product of the DO30 series calibrator, filling the gap of similar domestic products.
3. The standard source is suitable for calibrating and calibrating four-and-a-half-digit three-meters, various current and voltmeters, multimeters, resistance meters and calibration devices with corresponding accuracy. It can also be used as a high-level test power supply in conjunction with high-level standard tables. It is widely used in quality inspection, measurement, teaching and research and instrument maintenance in industrial and mining enterprises, scientific research institutes, railways, electric power, troops, schools and other units.
