Introduction
Features
2. In the case of no power failure, no change of metering circuit and no opening of metering equipment, the comprehensive error of metering equipment is detected by online real load.
3. Accurate measurement of voltage, current, active power, reactive power, phase Angle, power factor, frequency and other
electrical parameters, so as to calculate the measurement error of the test equipment circuit.
4. Optional virtual load box, when no load or ultra-low load, can also accurately measure the meter.
5. Can display the vector gram of tested voltage and current. User can check if the wire of metering equipment is correct or not though analyzing vector gram. Meanwhile, can identify 48 kinds of wring way automatically when use three-phase three wire connection method. Automatic calculation function of recovery power, which is convenient for users with wiring problems to calculate recovery power.
6. Clamp type transformer can test the current loop, user can measure conveniently and safely without break the current loop.
7. It can be used to check voltmeter, ammeter, power meter, phase meter and other indicating instruments as well as various active and reactive energy meters of three-phase three-wire, three-phase four-wire, single-phase 1A and 5A.
8. Photoelectric, manual, pulse and other methods can be used for electricity meter calibration.
9. Measurement and analysis of the AC power quality of the public power network to the client, the measurement and analysis: frequency deviation, voltage deviation, voltage fluctuation, three-phase voltage allowed unbalance degree and power grid harmonic.
10. Can display single-phase voltage and current waveform and can display three-phase voltage and current waveform at the same time.
11. Load fluctuation monitoring: measure and analyze the fluctuation of power quality of public power network caused by various electrical equipment in different operating states. Record and store voltage, current, active power, reactive power, apparent power, frequency, phase and other power parameters.
12. Power equipment adjustment and operation process dynamic monitoring, help users to solve problems in power equipment adjustment and operation process.
13. The dynamic parameters of reactive power compensation and filter devices in power system are tested and analyzed, and their functions and technical indexes are quantitatively evaluated.
14. With calendar, clock, real-time display date and time. Test data and results can be saved at the same time of on-site
verification, and uploaded to the computer through serial port. Data microcomputer management can be realized through background management software (optional accessories).
15. Adopts import large LCD screen as display, with multi parameter and indication, the interface is friendly.
16. Small size, light weight, easy to carry, can be used for field measurement, also can be used as the laboratory standard measuring equipment
