Density relay calibrator MDY-V the fifth generation of the fifth generation of software products Introduction of MDY-V density relay calibrator software developed at home and abroad the most powerful, best performance, especially small volume use the most convenient density relay calibrator instrument, which uses the embedded computer technology, measurement can be any valid within the SF6 density relay, pressure gauge, and automatically converted into the standard pressure value of 20 ° C when the corresponding SF6 gas density relay, pressure gauge accuracy check; meet DL/T596-1996 "electrical equipment preventive test procedures", "to prevent the 25 key requirements of the power production of a major accident on the SF6 gas density relay regular check requirements; SF6 density relay calibrator essential equipment. The fifth generation of software of MDY-V density relay calibrator performance characteristics to support arbitrary temperature standard pressure SF6 gas pressure to 20 ° C when translated with the the Standard pressure to 20 ° C when the pressure in any temperature conversion function support density relay 's alarm atresia and lift the performance verification to support dual latching density relay calibrator, digital density relay calibrator site without dismantling the entire checksum functionality directly check all Chinese and voice prompts, Chinese characters of large-screen menu, easy to operate volume is smaller, lighter weight, easy to carry imported miniature quick check valve, easy to operate, to prevent the line into the water, air, impurities instrument equipped with intelligent voltage protection system, misconnection 220V The voltage will not damage the calibrator, to use safer Dual temperature measurement, direct sampling, more accurate measuring instrument with RS232 or USB interface, support data analysis software to support mass storage, query history, built-in printer, ready to print The test results instrument self-diagnosis function when wiring errors can prompt AC and DC, built-in lithium battery overcharge protection of the fifth generation of software of MDY-V density relay calibrator technical parameters to distinguish accuracy of 0.25 pressure rate of 0.0001 Mpa measure pressure 0 ~ 1.0 Mpa methods LCD (Chinese) storage capacity of 100 sets of history stored measurement temperature range -30 ℃ ~ +100 ℃ temperature resolution of 0.1 ℃ Ambient temperature -30 ~ 60 ℃ (the best environment temperature 5 ~ 50 ℃) work power AC and DC AC220V 50Hz or machine lithium battery Dimensions 255 × 370 × 150 (mm) Weight 3.5Kg
