Product name: HCJ1311 three-phase electric energy meter field tester
Category: Electricity metering comprehensive test series

Detailed introduction

Product introduction

The instrument uses a large-screen color LCD as the display, a Chinese operation interface with Chinese character prompt information, and an LCD display interface with multi-parameter display. The human-computer dialogue interface is friendly, and the vector diagram display and wiring judgment provide a reliable basis for checking the correctness of the circuit. The full touch conductive silicone keyboard operation mode has a good operating feel and is simple and easy to learn. The instrument has a built-in large-capacity data storage device that does not lose data during power failure, which can save the field verification data and can store up to 10,000 sets of field verification results. It can provide background microcomputer management software to upload the results to the computer to realize microcomputer management.

Functional features

※ The instrument is a high-precision test instrument that integrates energy meter calibration, electrical parameter testing, and detection of power quality problems such as waveform distortion, voltage fluctuation and flicker, and three-phase imbalance in the power grid;

※ The comprehensive error of the online real load detection metering equipment is not interrupted, the metering circuit is not changed, and the metering equipment is not opened;

※ Accurately measure multiple electrical parameters such as voltage, current, active power, reactive power, phase angle, power factor, frequency, etc., so as to calculate the measurement error of the test equipment circuit;

※ Optional virtual load box, when the user has no load or ultra-low load, the meter can also be accurately measured;

※ The vector diagram of the measured voltage and current can be displayed, and the user can determine whether the wiring of the metering equipment is correct by analyzing the vector diagram. At the same time, in the case of three-phase three-wire wiring, 48 wiring methods can be automatically determined;

※ The current loop can be measured using a clamp-on transformer, and the operator can conveniently and safely measure without disconnecting the current loop;

※ It can calibrate indicating instruments such as voltmeters, ammeters, power meters, phase meters, and various active and reactive energy meters of 1A and 5A for three-phase three-wire, three-phase four-wire, and single-phase;

※ It is small in size, light in weight, and easy to carry. It can be used for on-site measurement and can also be used as a standard metering equipment in the laboratory.
