Digital Motor Checker

Digital portable diagnostic tool for Electrical Engineer and is used for quick on - site checks of electric motor and other three -phase machines. A reduction in machine performance, such as inefficient operation or tripping of overloads, may indicate mechanical or electrical faults. If the fault is electrical the EMC-28 will immediately defect it, without having to dismantle the equipment.
