Industrial Benchtop Micro-ohmmeter – High accuracy: 0.03 % – AOIP OM22 Milliohmmeter

The OM 22 table micro-ohmmeter is intended for 4-wire measurement of very low resistance resistances up to 20 KΩ with an excellent maximum accuracy of 0.03% and a resolution of only 0.1 µΩ. Equipped with 6 programs, it is particularly suitable for use on a bench for the execution of repetitive measurement tasks. The reliability and the precision of the measurements is reinforced by the low temperature coefficient (10 ppm / ° C), the automatic compensation of the electromagnetic forces before each measurement carried out, the temperature compensation of the nature of the metal and the compensation of the ambient temperature. .

With three forms of measurement current available – continuous, pulsed or alternating – from 100 µA to 10 A and flexibility in start-up and sampling conditions, the OM 22 covers a wide range of activity sectors and applications : resistance and resistivity measurement of cables, measurement of inductive resistances (motor coils, transformers, etc.), measurement of contact resistance (connectors, switches, relays, etc.), test of low power electrical components (fuses, etc.) and devices reacting to temperature, metallization control / earthing / earth continuity.

The OM 22 is a personalized device, ideal for use on a test bench: it has 6 programmable configurations that the user will select according to his wishes thanks to the 6 direct access keys on the front panel. Each program is complete and makes it possible to define the caliber, the current (shape and value), the number of measurements per cycle with their timing, the storage of the measurements, the possible temperature compensation, the unit of measurement, the calculations temperature or in W / km, the value of the alarms, the maximum measurement voltage, the analog output, the measurement triggering conditions, etc. If necessary, the OM 22 programs can be modified using the software LOG OM delivered as standard.

Up to 1000 measurement bursts can be saved in the instrument’s memory and can be read on the device screen directly or on a PC via LOG OM. Used on mains or rechargeable batteries, the electronic calibration of the instrument does not require any internal adjustment.
