Digital microhmmeter OM 10

portable4-wire

OM 10 portable 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. - 4-wire resistance measurement up to 50 KΩ at 10 µΩ resolution and 0.05% accuracy - Voltage measurement up to 400 V at 1 V resolution and 1% accuracy - Continuous measurement current for inductive loads: Coils, transformers, motor windings, twisted cables… - Pulse measurement current for non-selfic resistances: Earth bonding, ground continuity, contact resistances, non-twisted cables… - Automatic compensation of thermal E.M.F. - Temperature compensation - Metal temperature compensation Applications : Cable resistance and resistivity measurement Inductive resistance measurement (transformers, motors…) Contact resistance measurement (connectors, switches, relays…) Metallisation, earth bounding and ground continuity tests Tests of low power electrical components (fuses…) Tests of heat-sensitive devices Tests of surface states, mechanical bonds and materials
