Description The digital insulation tester model MD5KVR is TENTECH's cutting edge insulation analyzer equipment and it is one of the most complete and sophisticated available in the international market. A software allows for further analysis of tests results, including features such as graphical representation and automatic report generation. Its proven technology provides safe, reliable and accurate measurements of insulation resistances up to 5 TΩ, with 4 preselected test voltages, 500 V -1 kV - 2,5 kV - 5 kV. Other test voltages, from 50 V to 5 kV, can be selected in 25 V or 500 V steps. A state-of-the-art microprocessor controls the equipment operation and enables the incorporation of advanced features which make measurements easier: auto-range selection, AC/DC voltmeter, automatic measurement of absorption index, polarization index, leakage current and capacitance, timer enabling programming of test duration, configurable pass-fail test, dielectric discharge, ramp test, step voltage test, built-in printer, real time clock and calendar. Measured values are transmitted through the USB interface and are printed in the built-in printer as a registration of the performed test. Furthermore, the measured values are stored in a non-volatile internal memory. Up to 16,000 measured values may be stored to be transferred afterward to a computer running the T-Logger program. This software allows a further analysis of the test results, including a graphical representation and automatic report generation. The real time clock and calendar, and the sequential test number, facilitates the identification of each test, and the organization of a predictive maintenance system by trend analysis. The MD5KVR is powered by a rechargeable LFP battery. The cabinet is strong and lightweight, easy to carry, impact-resistant and suitable to be used under severe weather conditions. Thus the megohmmeter supplies very reliable and accurate measurements both in laboratory and out in the field. ▪ Microprocessor-controlled ▪ Insulation resistances up to 5 TΩ ▪ Auto-range ▪ Automated tests: Absorption index, Polarization index, Capacitance, Leakage current and AC/DC voltmeter ▪ IP65 protection ▪ Switchable filter to remove external noise interference ▪ Real time clock and calendar ▪ Built-in printer, internal memory for up to 16,000 measured values ▪ Software for data management Technical specifications TEST VOLTAGE 500 V - 1 kV - 2,5 kV - 5k V directly, one button selectable. 50 V to 5 kV in 25 V or 500 V steps.
