Franklin Tester Model FT-2 is designed as per IS:649 & ASTM:717 Standard to measure insulation resistivity of electrical steel sheet. It requires precision & noise free DC regulated power supply and equally distributed pressure on electrode. Franklin Tester FT-2 regulated power supply provides 0.5000V with 0.1% accuracy over load and no load. Most of national and international standard has specified only 0.5%, means FT-2 is equipped with five time better accuracy than required.
Franklin Tester FT-2 has spring loaded, ten brass electrodes and two carbide drill bit, mounted over hydraulic flat surface head. The head and electrode are precisely elevated and mounted on 4mm metal structure, that keeps alignment accurately for long time hence no need to align head and electrode periodically. Franklin Tester FT-2 has semi electrical hydraulic system in which two way solenoids switch provided for easy up and down the surface head. Double acting hand operated hydraulic pump provided, to which gives pressure rise in very less time to speed up the testing.
Franklin Tester FT-2 is micro controller based equipment, so it calculates all required mathematic function and simultaneously displays on character type 20×4 jumbo LCD display, Voltage, current and ohms per CM square. The FT-2 has provided with two separate ohms meter for sample surface side one and two and separate key S1 & S2 given. so just need to press S1 to take result for side1 & s2 to take result of side 2 and then press STOP for final result of both side.
Franklin Tester FT-2 has inbuilt Voltmeter, One multi range Ammeter, Two ohm meter and one added ohm meter for both side total value, hence user can see all data of all parameter simultaneously on display.
