Product Description
The ET-30B multifunctional calibrator is a digital AC and DC standard voltage and current generator with LCD display. The whole machine adopts "closed loop" control and has high output stability. It can be used for calibration of digital and pointer types. Meter and various AC/DC meter heads.This instrument has 11 voltage output ranges (0~1000V); current output 11 ranges (0~20A); median resistance 11×2 ranges (0Ω~20MΩ); AC frequency 50Hz, 60Hz, 400Hz (digital synthesis, button selection), The above items and range conversion are all converted by internal precision switches.The three windows simultaneously display the output actual value, percentage, and frequency. The output adjustment can be adjusted either by "position" or "percentage" adjustment. Using the latest 16-bit A/D conversion chip, the conversion speed and accuracy have been greatly improved; AC/DC uses a true effective value conversion chip to ensure the accuracy of AC output.A new type of composite high-power amplifier is used, with high output power, high reliability and low distortion.It has the advantages of digital display, wide range, fine division, high precision, good stability, and convenient use. 1.1,The whole machine adopts "closed loop" control with high output accuracy and stability. 1.2,Digital synthesis sine wave signal generator, low distortion, high reliability. 1.3,LCD screen display. 1.4,The output adjustment can be adjusted by "bit" or "percent".1.5,AC and DC voltage output range is 0~1000V.1.6,AC and DC current output range 0~20A. 1.7,Four alternative AC frequencies:50Hz,60Hz,400Hz. 1.8,Voltage short circuit, current open circuit automatic protection. 2,Technical index:2.1,Stability: AC<0.02%/5min of full scale DC<0.01%/5min of full scale 8-hour stability: 30% of accuracy2.2,Resolution:20ppm(0.002%)2.3,AC distortion:<0.5%,20A<2%2.4,DC ripple factor:<0.1%;20A<1%2.5,Output frequency accuracy<0.1%2.6,Dimensions:460×460×130(mm) Weight:about 18Kg2.7,Range and accuracy of output voltage, current and median resistance:Output item | Output range | Rated output | Maximum output | Accuracy |
