DO30-IA type three-use meter calibrator Brand: Huaguang Hi-Tech Tel: 0536-8222888 Website: online consultation Ali Wangwang free phone number WeChat communication DO30-IA three-use meter calibrator, multi-function calibrator, digital three-use meter calibrator, meter calibration device 1, purpose, characteristics: DO30 -Type IA multi-function calibrator is an intelligent AC, DC standard voltage, and current calibrator (where AC output is displayed as a true rms value). The instrument has three display windows, which can simultaneously display the output actual value, percentage, and full value of the inspected table. The output range of the instrument can be set according to the full value of the inspected meter, and the corresponding stepping amount can be selected according to the scale of the inspected meter. The output adjustment can be selected from keyboard (key) control or potentiometer control. It has the characteristics of digital display, direct error reading, wide range, fine grading, high precision, good stability, easy to use, etc. Suitable for calibration, inspection and maintenance of four-digit half-digit three-purpose meters, all kinds of pointer AC, DC voltage and ammeters of grade 0.2 and below 0.5. It can also be used as a high-stability test power supply, and calibrate 0.1 grade current and voltmeters with high-grade standard meters. 2. Main functions: 1, 51/2 LED digital display output, according to the actual value and percentage at the same time. 2. Use the keyboard to control the increase or decrease of the output volume. The keyboard control amount is divided into /N, 10% /N, 1% /N, 0.1% /N (N is 4, 5, 6, 10, 15). 3. The external control regulator can control the increase or decrease of the output amount off the machine. The regulator has two configurations, a keyboard and a potentiometer, and can be converted arbitrarily. 4. The AC and DC voltage output range is 0~1050V. 5. AC and DC current output range is 0~10A. 6. AC provides four output frequencies: 50Hz, 60Hz (59.7Hz), 400Hz, and 1000Hz. The crystal oscillator is used to ensure the accuracy and stability of the frequency. 7. Automatic protection of output overload and manual reset. 8. The AC 50Hz output can also be synchronized with the mains to reduce the influence of the beat frequency of the meter being inspected. 9. Clamp meter measurement: equipped with our factory's standard coil, it can measure 0~1000A current, with an error of ± 0.3%. 4. Technical performance: 1.
