Standard source based on single chip as the core, using digital technology, large loop amplitude stabilization tracking, true rms converter, high power amplifier, automatic protection shell type self calibration and other advanced technologies. Make its stability, accurate degree high, linear goodness, wide range, safe and reliable, applicability strong characteristics, output amplitude regulation with numeric keys, the encoder and sub grid step three adjusting combination, the flexible control, the reaction rate achieve continuous and constant output of different needs. The operation is more convenient and practical, is the replacement of DO30 series of calibration equipment, to fill the blank of similar products in the country.
Standard source is applicable to verification, calibration, four and a half digital three tables, the corresponding precision of all current, voltage meter, multimeter, resistance meter and calibration devices. Can also be used in high level test power supply with high level standard. Widely used in industrial and mining enterprises, scientific research institutes, railways, electricity, troops, schools and other units of quality control, metrology, teaching and research and instrument maintenance, etc..
