Onsite micro-ohmmeter up to 50 KΩ and 100 mA OM 10 micro-ohmmeter performs 4-wire measurements of inductive and non-inductive resistances up to 50 kΩ with continuous or pulse measuring current up to 100 mA. It works at a resolution of 10 µΩ and an accuracy of 0.05%. The accuracy of measurements is also ensured by the automatic compensation of thermal electromagnetic forces, the compensation of ambient temperature (internal sensor) at 20°C and by the selection of the metal type.OM 10 can also measure DC and AC voltages up to 400 V.
