120 V operation Makes measurements by passing a current through the conductor under test and also monitoring the voltage across it Test current is limited by a simple current limiting circuit and is measured by monitoring the voltage across a resistor Test current is maintained at a nominal 2 A, and as the measurement is ratiometric, the reading is unaffected by any current variations High test current Four terminal measurement Two measuring ranges (2000 mO. and 20,00 mO.) and maximum resolution of 0,01 mO Protected against inadvertent connection to the mains supply > Each Unit Includes Supply Lead for Battery Charger Duplex handspikes with 8ft test leads Instruction Book
