1. Main functions and features
Three-way mutual insulation voltage input channel isolation, a current three-way Clamp current transformer input, safe and reliable. Can be continually measured in the circuitry at the same time AC voltage measurement 1-3 Road 1 - 3-way exchange of the current amplitude and the phase of the measured single / three-phase power and power factor, frequency measurement. Vector plans to measurement results, tables, multiple-access format.
1) Set Table voltage three-phase, three-phase pincers ammeter, phase table, phase sequence tables, frequency meter, power meter, power factor function in a seven table;
2) touch-screen operation, the Chinese character handwriting input;
3) 320 x 240 high-resolution color TFT screen, clear graphics display delicate;
4) measurement results in a variety of ways, real-time display vector maps, discriminant wiring errors;
5) all six input isolation, support a variety of wiring, can be arbitrary measurement between the two input phase;
6) voltage and current TRMS measurement principle, automatic range;
7) support software user calibration;
8) measurement data storage without quantitative restrictions, the measurement results can be joined Note, automatically records time measurement, the operator and other information;
9) ultra-low-power, two AAA batteries can be on the 5th working continuously for more than 36 hours and a standby time longer support an external power supply and charging; battery replacement convenience, the factory equipped with large-capacity rechargeable battery, and can also use batteries;
10) new small high-precision current clamp;
11) data can be exported to standard Web format, with forms and vector maps, editing and production of reports;
12) supports data upload computer, using computer data on the Pocket PC browser, export, edit, print, backup and restore functions;
13) infrared printer scene A4 colour printing;
14) on-line electronic documents, ready access to help;
15) software to support Microsoft's latest mobile operating system, Windows Mobile 5.0 and Pocket PC2003, system functions can be extended with software upgrades.
