MILLIOHMMETER & MICROHMMETER

MICROHMMETER AND MILLIOHMMETER ARE LOW RESISTANCE METERS DEDICATED TO MEASURE AN OHMIC VALUE UNDER A DEDICATED CURRENT
They are based on two main circuits : an extremely stable current source + a high impedance and very accurate voltage measurement system for real 4 wire measurement method (also called Kelvin method)

APPLICATION
MANUFACTURER, HIGH SPEED PRODUCTION, MAINTENANCE, LABORATORY, BUT ALSO AERONAUTICAL INDUSTRY


• cable manufacturer (measurement on 1 meter cable sample, …) with MGR10
microhmmeter
• electric motors, generators (test of the winding resistance for the determination of heat rise) with MGR10 microhmmeter
• resistors, fuses, transformer windings, transducers, coils, printed circuit boards … with MGR10 microhmmeter
• automotive component manufacturer (test of air bag and seat belt detonator resistance, of the ABS braking system coils, ...) with MGR10C microhmmeter
• delectric/electronic component manufacturer, relays, connectors (measurement of the switch contact resistance, relay contact resistance, ...) with MGR10B microhmmeter
• rockets, launch vehicles, tanks, planes, helicopter bondings (also called bonding test or metalisation) for production and maintenance with RCP2A
• household, industrial equipment, medical industry, information technology industry, measurement, control and laboratories industry in order to validate that all the touch accessible parts are properly connected to the protective earth connection, according to the quality standards from the Low Voltage Directive (LVD), applicable to the corresponding standards (IEC335, IEC950, IEC601, IEC1010, IEC598, IEC990, IEC204...) with CMG30
bonding tester

SPECIFICATION OVERVIEW
FROM LABORATORY TO PRODUCTION TESTING AND MAINTENANCE, OUR RANGE IS MADE OF 3 FAMILIES
• very low measurement resistance measurement from 0.1 µΩ up to 10 A with MGR10 microhmmeter
• temperature compensation for copper and aluminium (but also any additional materials) with MGR10 microhmmeter
• 10A pulsed current with a 600 mΩ range for measurement on dissimilar materials (also called composite) with RCP2A
• ground bond test up to 40A (typical resistance limits 100 mΩ, 200 mΩ or 500 mΩ) with CMG30
• GPIB, RS232, 0-10V, PLC available
• Smg Pro, RCP2A Pro & MGR10 Pro software for quality purposes, traceability and professional reporting
