10kV Diagnostic Insulation Tester MT577<\/strong><\/p>\n

The MT577 10kV Diagnostic Insulation Tester provides precise increments of 50V on each range and automatically discharges the circuit after every test. By using the range button switches, you can select six preset ranges: 250V, 500V, 1000V, 2500V, 5kV, and 10kV. With insulation resistance up to 35T\u03a9, the microprocessor\u2011controlled MT577 serves as a reliable diagnostic tool for insulation testing on rotating machines, transformers, cables, high\u2011voltage generators, electric circuits, and surge arresters.<\/strong><\/p>\n

In addition, the MT577 delivers a short\u2011circuit current output of up to 6mA. It measures Absorption Ratio and Polarization Index for both AC and DC voltage. You can save up to 500 test results in the meter\u2019s memory and recall them directly on the LCD display. The large backlit LCD clearly shows insulation readings, measuring time, output voltage, and output current. Furthermore, the MT577 measures AC voltage up to 750V, DC voltage up to 1000V, and capacitance up to 50\u03bcF. Housed in a robust case, it is ideal for extended field use and powered by 12.6V lithium batteries. Finally, stored data transfers easily to a PC via optical USB and supplied software, streamlining reporting and analysis.<\/strong><\/p>\n<\/div>\n
