The Milliohm Meter TP-MM3000 is an instrument that allows your oscilloscope to measure small resistances with high accuracy.
The Milliohm Meter TP-MM3000 is particularly useful for checking and measuring the impedance of stator coils of electric motors.
The Milliohm Meter TP-MM3000 determines the resistance by running a current through the component and measure the voltage across the component.
Special Kelvin clips are used to perform a 4-wire sensing measurement. This is an electrical impedance measuring technique that uses separate pairs of current-carrying and voltage-sensing electrodes. That allows to make more accurate measurements than the simpler and more usual 2-wire sensing. Separation of current and voltage electrodes eliminates the lead and contact resistance from the measurement. This is an advantage for precise measurement of low resistance values.
