Equipment ELMA 8x01 is a „table execution“ of test equipment for measurement, adjustment or calibration of small number of meters.
Properties
- Accuracy class of equipment (reference meter) can be up to 0.01 % according to laboratory demand;
- The available power and the maximum current of 240 A of extremely pure synthesized 4-quadrant test signal covers the needs on both precision and high capacity testing laboratories;
- The intelligent high resolution Local Evaluation Units use reflective optical sensors, scanning the marks on meter's disk and passive sensors, scanning the LED test output of electronic meters;
- Suspension frame for 1, 2 or 3 positions is equipped with quick-acting connector system;
- The optional precision electronically compensated transformers enable simultaneous test of electricity meters with interconnected current and voltage circuits;
- The supplied Control Software for Microsoft Windows enables multilingual operation with user definable vocabularies, user friendly configuration of testing procedures, database operations and Microsoft Office compatible user defined form of output documents to any system output device;
- Optional local net and database ensures automated data interchange, central evaluation and archivation in laboratories with multiple test equipments.
