2. Unique power switch and amplifier technology, so the output precision and power efficiency and factor are increased, which conforms to international tendency of energy save and environmental protection;
3. With alarm function of housing grounding testing and external voltage input, to guaranty personal security;
4. Offer independent Aux. DC to tested devices, 0 ~ 300V/0.6A(Poleless and adjustable);
5. Two in one of meter and source, with function of both internal and external testing, self-calibration, oscillograph, and the duration of each oscillograph reaches 50S (optional function);
6. Function of transducer and energy meter testing (optional function);
7. Adopt Smart and stable Window CE embedded system. Windows has the advantage of small application program with fast speed, which overcomes the problem of bad stability, easy-damage hardware, and virus of Windows 98/2000/XP;
8. Use high-speed CF card as the storage, more stable, anti-shock compared with ordinary hardware, so works more reliable.
