GF3021 Portable Multifunction Instrument Calibrator with highest
accuracy class and stability
(Accuracy class 0.05%/0.1%)
Introduction
GF3021 Portable Multifunction Instrument Calibrator is suitable for
power plant and power grid companies for the following function:
measuring and testing department and instrumentation classes,
national levels measuring and testing institutions, railway,
petroleum, chemical industry and other large industrial and mining
enterprises, scientific research units, etc. The core technology
function with digital signal processor (DSP) and 16 high-speed
digital converters composed of high precision work frequency
communication terminal. The signal source is DSP and 16 high-speed
digital-to-analog converters, it can control the sine wave and
distortion wave signal source.
