| The MPK-254 digital very low resistance
ohmmeter is a portable, microprocessor-controlled instrument
used to accurately measure resistances of switches and circuit
breaker contacts, transformer and motor windings, wire and cable
samples, joints in busbars, etc., using test currents from 1
mA up to 5 A. It uses the Kelvin-type, four-terminals measurement
principle, thus eliminating errors caused by lead and contact
resistances. |
