Product Introduction:
YTC2089 Handheld MultifunctionalOn site verification instrument for electric energy meterIt is a high-precision testing instrument developed and researched by our company, which integrates measurement of electrical parameters, calibration of electric energy meters, and wiring judgment. The instrument is equipped with high-precision and high linearity voltage transformers and current transformers, which enable the instrument to measure various parameters with high accuracy. At the same time, it is equipped with clamp type current transformers, which make on-site wiring simple and can be directly connected without disconnecting the current circuit.

Product features:
1The instrument is a high-precision testing instrument that integrates the verification of energy meters, electrical parameter testing, and detection of waveform distortion, voltage fluctuations and flicker, and three-phase imbalance in the power grid.
2Under the condition of no power outage, no change to the measuring circuit, and no opening of the measuring equipment, the comprehensive error of the online real load detection measuring equipment.
3Accurately measure various electrical parameters such as voltage, current, active power, reactive power, phase angle, power factor, frequency, etc., in order to calculate the measurement error of the testing equipment circuit.
4It can display the vector diagram of the measured voltage and current, and users can analyze the vector diagram to determine the correctness of the wiring of the measuring equipment. At the same time, in the three-phase three wire wiring mode, 48 wiring modes can be automatically determined.
5The current circuit can be measured using clamp type transformers, and the operator does not need to disconnect the current circuit, making it convenient and safe for measurement.
6It can verify various indicating instruments such as voltmeter, ammeter, power meter, phase meter, as well as three-phase three wire, three-phase four wire, single-phase 1A, 5A active and reactive energy meters.
7Electric energy meter calibration can be carried out using photoelectric, manual, pulse and other methods.
8Measure and analyze the quality of AC power supplied by the public power grid to the user end, including frequency deviation, voltage deviation, voltage fluctuation, flicker, allowable three-phase voltage imbalance, and grid harmonics.
9It can display single-phase voltage and current waveforms and simultaneously display three-phase voltage and current waveforms.
10Load fluctuation monitoring: measuring and analyzing the fluctuations caused by various electrical equipment in different operating states on the power quality of the public grid. Record and store power parameters such as voltage, current, active power, reactive power, apparent power, frequency, phase, etc.
11Dynamic monitoring of power equipment adjustment and operation process, helping users solve problems that arise during the adjustment and operation of power equipment.
12Test and analyze the dynamic parameters of reactive power compensation and filtering devices in the power system, and quantitatively evaluate their functions and technical indicators
13Equipped with perpetual calendar and clock functions, real-time display of date and time. At the same time as on-site verification, test data and results can be saved and uploaded to a computer through a serial port, and data can be managed through a backend management software (optional accessories) to achieve computerized management.
14Adopting imported color LCD with a large screen as the display, the Chinese operation interface is equipped with Chinese character prompt information and multi parameter display LCD display interface, and the human-machine dialogue interface is friendly
15Small in size, light in weight, easy to carry, can be used for on-site measurement, and can also be used as standard measuring equipment in laboratories.
