OM 10 portable micro-ohmmeter performs 4-wire measurements of inductive and non-inductive resistances up to 50 K? with continuous or pulse measuring current up to 100 mA. It works at a resolution of 10 µ? 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.
Key-features :
- 4-wire resistance measurement up to 50 K? at 10 µ? 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 :
