XF30A+multifunctional calibrator

1、 Purpose and characteristics:
The XF30A * multifunctional calibrator is an intelligent AC and DC standard voltage and current calibrator. (The communication output is displayed as true significant value). Three windows simultaneously display the output actual value, percentage, and checked table full value. It is possible to set the full-scale value of the inspected table and select the corresponding step size based on the scale of the inspected table. The amplitude adjustment can be controlled by keyboard (key) or potentiometer. It has the characteristics of digital display, error direct reading, wide range, fine grading, high accuracy, good stability, and easy use. Suitable for calibration, verification, and repair of four and a half digit multimeters, as well as various pointer type AC and DC voltage and current meters with levels 0.2 and 0.5 or below; 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: 5 1/2 digit LED digital display output, displaying both actual value and percentage simultaneously.
2: Use keyboard to control the increase or decrease of output volume. The keyboard control quantity is divided into 100%/N, 10%/N, 1%/N, and 0.1%/N (N is 4, 5, 6, 10, 15).
3: The external control regulator can control the increase or decrease of output quantity off the machine, and there are two configurations on the regulator: keyboard and potentiometer, which can be converted freely.
4: The output range of AC and DC voltage is 0-1000V.
5: The output range of AC and DC current is 0-20A.
6: There are four AC frequencies available for selection: 50Hz, 60Hz (59.7Hz), 400Hz, and 1kHz (with crystal oscillator to ensure frequency stability).
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: 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<0.02% of full scale/5 minutes
DC<0.01% of full scale/5 minutes
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 synchronization)
5: Output voltage, current, and median valueresistanceRange and accuracy (23 ℃± 2 ℃, output value greater than 10% range)
