HIOKI 3194 Motor / Harmonic HiTester Up to 6 input channels for analysis of inverter motors and high-order harmonics. The 3194 provides Analysis of high-order harmonics up to the 3000th order. This makes it Ideal for analyzing and evaluating the performance of inverter motors and for harmonic analysis of household appliances. Additionally, With the optional unit 9603-01 installed, the HiTESTER can directly measure torque and rotation speed, an essential feature for evaluating the performance of inverter motors.
Main unit 3194 cannot operate alone. A factory option input unit the 9600 to the 9604 must be purchased. In the event of unit replacement or extension, the work involved is done at the factory, and unit cost + service fee are charged.
