Main features
- 7-inch (800 * 480) TFT true color LCD display, graphical operation interface, can be operated by touch screen or manual button operation, the interface display is clear and intuitive.
- Measure the phase separation and total power of three-phase voltage, current, frequency, active power, reactive power, apparent power, and power factor, and display multiple phase relationships such as U-U, U-I, and I-I. Provide Chinese prompts for positive and negative phase sequence.
- The measurement results can be displayed in various ways such as vector graphics and tables, with over 20 parameters displayed on the same screen, making the measurement data clear at a glance.
- Automatically identify the load characteristics of the power line, check the secondary circuit of the power line, automatically identify the three-phase four wire and three-phase three wire connections, indicate the incorrect position, display the secondary circuit wiring diagram and power expression, and automatically calculate the correction factor.
- Load curve recording and load fluctuation monitoring function: It can measure the fluctuations caused by various electrical equipment in different operating states on the power quality of the public grid, and dynamically monitor the adjustment and operation process of power equipment.
- Waveform display and harmonic analysis: It can measure the harmonic content and amplitude below the 31st order of voltage/current, and display them in a histogram.
- The wiring simulation function can be used as a training tool for wire inspection, improving the wire inspection skills of on-site workers. The instrument can obtain corresponding wiring results based on on-site data without connecting voltage and current signals.
- PT/CT settings can convert secondary data into primary data.
- Calculation of voltage and current imbalance.
- Vector calculator, on-site calculation of voltage and current vector sum.
- Optional 3000A flexible ratio clamp for measuring low-voltage current transformers, displaying angle difference, ratio difference, and polarity discrimination.
- Built in standard Chinese character library, using Pinyin Chinese character input method to input Chinese characters/letters/numbers and other stored content.
- Dual power supply: The measuring end is directly powered and the high-performance lithium battery is used for power supply. The lithium battery powered instrument can work continuously for 10 hours.
- The power automatic power-saving management function can automatically shut down or enter sleep mode.
- Built in memory, capable of storing 4000 sets of measurement data, allowing access to saved data sets and vector graphs.
- Support data uploading to computers, allowing for direct browsing, export, editing, printing, backup, and other functions of instrument data. It can also be exported as standard EXCEL format files and generate experimental reports.
- The instrument is equipped with a USB interface to transfer measurement data through a USB drive.
- The instrument is equipped with an RS232 interface, which can be connected to a computer for data upload and instrument data correction.
- Optional micro printer for on-site printing of measured data.
- Optional data acquisition dedicated software can be configured, with the host serving as an communication data acquisition module connected to the computer, to collect real-time on-site data and automatically draw curve graphs for data analysis and management. And conduct 24-hour real-time data collection and monitoring of on-site electrical equipment, detect three-phase load imbalance and load fluctuation process monitoring.
- Handheld, small in size, light in weight, anti drop wrist guard to prevent operators from accidentally damaging the instrument.
