 Tester HT7050 is intended for the high-precision and reliable measurement of insulation resistance. These are light before the use instrument is made it possible make it possible to conduct measurements with the stress from 500 to 5000[V], controlling all parameters (insulation resistance, stress, the time of measurement). Instrument widely is used for measuring the insulation resistance of the revolving machines, transformers, isolation of systems with the high voltage, electros-cable. It also is used for the definition of the degree of reduction in the isolation, caused by the ambient conditions for operation, such as corrosion, dust, humidity and the like.
Basic functions
- measurement before the manual regime
- measurement before the automatic regime
- time setting of the measurement
- the installation of the programmed parameters of the test
- the measurement of the index of the polarization
- the writing of the obtained results into the memory
- the printout of the obtained results
- the built-in interface RS-232
