EQUITEST 5070 - is this portable multifunctional tester for measuring the resistance of shielding wires in the medical accomodations, test of electrical conductivity according to EN60204-1, measuring the low resistances between the input terminals of shielding wires and corresponding equipment, quality control of contacts, and also the conductivity of concrete of reinforcement. Instrument create the current of higher than 10A for the resistances below 0.5 Ohm (max. the stress of test from 6 [do]12[V]) and are used 4 wire diagrams of connection for decreasing the influence of the contact resistance and wires.
