The INMEL 1000 calibrator was made on base of modern componenets of microprocessor technologies. Applicated technologies are comparable with technologies used by leading global companies.The INMEL 1000 calibrator characterize oneself the innovative structure of operation in range of output signals and operation of measuring and regulatory loop.For AC course possible is the synchronous operation with the main. This possibility influence on output parameters, reliability, comfort of work, the communication way with user and external devices. The calibrator INMEL 1000 fulfils directives of the European Union within the range safeties and the electromagnetic compatibility:The production of the INMEL 1000 calibrator does not create threats for environment. Application: Checking ang calibration: - AC and DC voltmeters, - AC and DC ammeters, - frequency meters, - measuring transducers.
