Overview

The AC/DC indicator calibration device is an intelligent calibration system that integrates a high stability AC/DC standard source, precision measurement unit, and automatic calibration software. It can output precise and controllable signals such as voltage, current, power, phase, frequency, etc., covering a wide range from millivolts to kilovolts, microamperes to microamperes. At the same time, it has high resolution, low distortion, and excellent long-term stability, and can perform full function calibration on various types of analog pointer or digital indicator instruments from 0.1 to 2.5 levels.

Product Details

In power systems, industrial automation, rail transit, and scientific research laboratories, various types of AC/DC voltmeters, ammeters, power meters, frequency meters, phase meters, and other indicating instruments are widely used in operation monitoring and control processes. The accuracy of these instruments is directly related to the fairness of energy measurement, the safety of equipment operation, and the precision of process control. To ensure reliable traceability of its measurement values and compliance with national metrological verification regulations,AC/DC indicator calibration deviceAs a high-precision and multifunctional standard source and detection platform, it has become a core equipment for various levels of metrology institutions, power supply enterprises, power plants, and large industrial and mining enterprises.

The calibration device for AC/DC indicator instruments is a type of integrated deviceHigh stability AC/DC standard source, precision measuring unit, automatic calibration softwareAn integrated intelligent verification system. It can output precise and controllable signals such as voltage, current, power, phase, frequency, etc., covering a wide range from millivolts to kilovolts, microamperes to microamperes. At the same time, it has high resolution, low distortion, and excellent long-term stability, and can perform full function calibration on various types of analog pointer or digital indicator instruments from 0.1 to 2.5 levels.

The core advantages of this device are reflected in the following aspects:

Multi functional integrated designA single device can complete the calibration of various parameters such as voltage, current, active/reactive power, power factor, phase angle, frequency, resistance, etc. It supports multiple wiring methods such as single-phase, three-phase three wire, three-phase four wire, etc;
Intelligent automation verificationThe supporting specialized software can automatically set test points according to regulations, collect the measured values, calculate errors, determine whether they are qualified or not, and generate electronic reports that comply with the format, greatly improving the efficiency and standardization of calibration;
Good load adaptabilityThe output terminal has strong load capacity, which can drive high impedance voltmeters or low impedance ammeters, and the output waveform distortion is low, ensuring that the calibration results truly reflect the instrument performance;
Human computer interaction friendlyEquipped with a large-sized color LCD screen, physical knobs, and touch operation, it supports manual fine-tuning and automatic stepping, which is suitable for both batch automated calibration and on-site single meter debugging.
