1、 Purpose and characteristics:
HG30A-3 typeMulti functional calibratorIt is an intelligent AC and DC standard voltage and current calibrator (with AC output displaying true RMS). The instrument is equipped with three display windows, which can simultaneously display the output actual value, percentage, and the full-scale value of the tested meter. The output of the instrument can be set based on the full-scale value of the inspected tablerangeAnd the corresponding step amount can be selected according to the scale of the tested meter. Output adjustment selectablekeyboard(Key) control or potentiometer control. Equipped with digital display, error direct readingrangeFeatures such as width, fine grading, high precision, good stability, and easy use. Suitable for calibration, inspection, and maintenance of four and a half digit multimeters, as well as various pointer type AC and DC voltage and current meters at or below level 0.2 and 0.5; It can also be used as a high stability testing power supply, in conjunction with high-level standard meters, to calibrate 0.1 level current and voltage meters.
2、 Main functions:
1. 5¹/₂The LED displays the output quantity in two ways: actual value and percentage.
2. AdoptingkeyboardControl the increase or decrease of output quantity.keyboardThe control quantity is divided into 100%/N, 10%/N, 1%/N, and 0.1%/N (N is 4, 5, 6, 10, 15).
3External control regulatorIt can control the increase or decrease of output quantity off the machine, and there is a regulator on itkeyboardThere are two configurations of potentiometer, which can be freely converted.
4. The output range of AC and DC voltage is 0-1050V.
5. The output range of AC and DC current is 0-25A.
6. Communication provides four output frequencies: 50Hz, 60Hz (59.7Hz), 400Hz, 800Hz, 1200Hz, usingcrystal oscillatorEnsure the accuracy and stability of frequency.
7. Output overload can be automatically protected and manually reset.
8. AC 50Hz output can also choose mains synchronization to reduce the impact of the frequency of the tested meter.
9. Clamp meter measurement function: equipped with our standard coil, it can measure current from 0 to 1000A with an error of ± 0.3%.
3、 Technical performance:
1. Stability: AC<fullrange0.02%/5 minutes
DC<Fullrange0.01%/5 minutes
When making precise measurements, the instrument needs to be preheated for two hours.
2. Communication distortion:<0.5%
3. DC ripple factor:<0.05% (at rated output)
4. Output frequency accuracy: 50Hz, 60Hz (59.7Hz), 400Hz, 1KHz ＜ 0.1% (or mains synchronous)
5. Output voltage, current, and median valueresistanceThe range and accuracy are shown in Appendix 1 (23 ℃± 2 ℃, output value greater than 10%)range）
