The Megger? FT6/12 Mk 2 is an a.c./d.c. breakdown, leakage, and ionization tester. The instrument supplies a continuously variable output voltage of up to 12 kV d.c. or up to 6 kV a.c. RMS each in two ranges. Provision is made for the measurement of a.c. and d.c. leakage current, the detection of ionization, and the indication of breakdown from the item under test. The total leakage current and the in-phase leakage current are indicated; a.c. capacitive current and both a.c. and d.c. leakage resistance can be calculated. Panel meters are used to show the output voltage level and the leakage current value. The instrument can be set so that the voltmeter shows the level at which the breakdown occurred. APPLICATIONS The FT6/12 Mk 2 is used for flash testing and nondestructive insulation testing of materials, electrical components, and equipment, with measurements of the breakdown voltage easily made. The source impedance of the output voltage is low enough to permit the rapid testing of high capacitance components, and at the same time automatically limiting the available output current. The facilities provided for remote control of the instrument make it very suitable for mounting permanently as part of a test equipment console. FEATURES AND BENEFITS
