The micro-ohmmeter for field use is able to measure metallisation type or winding measurement low resistances on site and has a long battery life.
Measuring current of up to 10 A - Resolution 0.1 μΩ.
Ranges from 5 mΩ → 2500 Ω.
Choice of type of resistance measured - selfic or non-selfic.
DC measurement.
Measurement trigger: Manual or automatic.
Pliers and measurement points connected by locking sockets to avoid connection errors and unwanted disconnections.
Measurements on 4 wires of pure and highly selfic resistances such as:
- Power supply cable
- Earthing check:
- Mechanical connection:
- Engine, windings, high power transformers
-Metallisation and resistance of contacts
-Measurement on fuses
- Cable strands.
Recording of 1500 values with identification and reading on the display or using the LOG OM software.
Automatic compensation for EMF parasites, eliminating errors in measurement.
Display of the measured resistance value at a programmable temperature in °C, depending on the ambient temperature and the temperature coefficient of the metal being measured.
Power supply with quick-charge battery, providing 5000 measurements at 10A.
Integrated battery charger, 90 → 264 V / 45 → 420 Hz.

The Aoip Instrumentation digital micro ohmmeter operates in different ranges selectable between 5mohm and 2.5kohm with high precision of 0.05% and 0.1μohm resolution. This ohmmeter allows longer tests to be performed at 10A with a continuous current for up to 60 minutes and offers faster current loading of coil resistances with stabilization time less than 2 seconds. This instrument is easy to use and carries out 4-wire measurements of inductive and non-inductive resistance with a continuous or pulse current up to 10A.
