Aoip OM 17 Field 10 A Micro-Ohmmeter

Designed for field use -in workshops or outdoors-, OM 17 micro-ohmmeter is a field instrument, whose performances are as high as a laboratory instruments’.Succeeding OM 16, OM 17 offers upgraded performances, in particular for inductive resistance measurements: Granted with a greater autonomy, OM 17 allows longer test campaigns to be performed at 10 A with continuous current (up to 60 min) and offers faster current loading of coil resistances (stabilization time < 2 s).Easy to use, it carries out 4-wire measurements of inductive and non-inductive resistance with a continuous or pulse DC current up to 10 A. Offering a high precision of 0.05% and a 0.1 µ? resolution, it has a different ranges selectable from 5 m? to 2.5 k?.Key features:4-wire measurement of inductive and non-inductive resistanceContinuous or pulse DC current, from 1 mA to 10 APrecision: 0.05% ReadingAutomatic EMF compensationAmbient temperature compensation (measured or programmed)Compensation of metal temperature coefficientChoice of reference temperature2 programmable thresholds with visual and sound alarmMemory: 1,000 measurements identifiedIdeal for long tests at 10 A continuous over transformersEasy to use, rugged and protected against rough environment (IP 53 when opened / IP 64 when closed, lockable measurement plugs), OM 17 is widely recommended for indoor and outdoor use in many industries:AerospaceEnergy fieldDomestic electrical appliancesCable manufacturingTelecommunicationElectronicsAutomotive industryRailwayVarious fields of applicationsMetallization and earth bonding controlWelding quality controlContact resistance measurement (low voltage connectors, relays…)Test of electronic componentsCoil, transformer and motor resistance measurement, loss and heat rise calculationNon-twisted and twisted cable resistivity measurement and length calculationRailway and electric network maintenanceTwo current waveformsContinuous DC currentInductive resistance and coilsAutomatic trigger of measurements when using a trigger test probeEMF compensation before measurementsCourant pulséNon-inductive resistanceAutomatic trigger of measurements as continuity is established – 1 operator neededAutomatic current shutdown at the end of a measurementEMF compensation before every measurementConfiguration and displayAll parameters are user-programmable, either directly through the instrument interface or via software (LOG OM, available in option) :Measuring current, range, resistance type, unit, reference temperature, alarm threshold value & status and calculation...OM 17 large display informs the operator in real time about the measurement itself and the measuring conditions. Any detection of range overshoot, open circuit or low battery is indicated by LEDs and message displayed on the screen.Before every measurement, EMFs are measured and automatically removed for a greater accuracy of measurements. For non-inductive resistances, a single operator is enough to perform the measurement since it will be automatically triggered once continuity is established between the two points.The user can also set the metal nature or its temperature coefficient, the reference temperature and the ambient temperature. The ambient temperature might be also measured by an external temperature probe.Battery-powered, OM 17 has a high storage capacity of 1,000 measurements to be read directly on the display or via Log OM software.Protection up to 250 V is ensured at every measurement terminal, while any overrange, open circuit or empty battery signal detected is notified by LEDs and messages displayed.
