The YTC2220S three-phase clamp phase voltmeter is manufactured in accordance with the national standards "JJG124-2005 Verification Regulation of Ammeters, Voltmeters, Wattmeters and Ohmmeters", "SD110-83 Verification Regulation of Electrical Measuring Instruments", "JJG780-92 Verification Regulation of AC Digital Power Meters", and the relevant requirements for portable on-site instruments.
Product Features:
1. Adopts a 3.4-inch LCD display with clear and intuitive interface;
2. Measures and displays three-phase voltage, current, phase, and six-vector diagram; real-time measurement of active power, reactive power, apparent power, frequency, and power factor for individual phases and total power;
3. Measures phase with small current of 1.5mA, very suitable for checking wiring conditions when new users have no load after commissioning;
4. High measurement accuracy and wide measurement range;
5. Can measure from the secondary side and automatically convert to primary side electrical parameters;
6. Equipped with a 500A current clamp for current transformer measurement, displaying angle difference, ratio difference, and polarity discrimination;
7. Automatically identifies line load characteristics and judges wiring errors for three-phase three-wire and three-phase four-wire systems, covering 1008 types of energy meter wiring errors, and indicates the error location;
8. Measurement results are displayed in various forms such as vector diagrams and tables, with multiple parameters displayed on the same screen for clear data viewing;
9. Dual power supply: powered directly from the measurement terminals and high-performance lithium battery;
10. When powered by lithium battery, the instrument can work continuously for 18-30 hours; standby time ≥60 hours, charging cycles ≥500 times;
11. Built-in memory can save 200 sets of measurement data, and saved data sets and vector diagrams can be viewed;
12. Automatic power-saving management function, can automatically shut down or enter sleep mode;
13. Built-in clock chip for accurate recording and display of measurement time;
14. Supports data upload to computer, allowing direct browsing, exporting, editing, printing (A4 size), and backup of instrument data, and can be exported as standard EXCEL files and generate test reports;
15. Implements browsing and querying of test results, combining Chinese menu with direct button operation, easy to learn and use;
16. Built-in help menu for convenient on-site operation;
17. Humanized design with anti-drop wrist strap to prevent damage to the instrument from operator mishandling;
18. Ultra-compact structure design, handheld, small size, and light weight.
