The Kewtech KT31 is a high quality analogue tester for the traditionalist who likes to see the swing of the needle.
An Insulation/Continuity Tester performs two basic functions. As a continuity tester the instrument can be used to measure 3 low values of resistance between two points in an electrical circuit. In this mode the instrument acts as a low voltage current source. The resistance is calculated from the measurement of the voltage and the current through the conductor. Careful connection to the circuit under test is essential to avoid measurement errors. Circuits connected in parallel to the circuit under test may also effect the accuracy of the measurement.
Robust new style dual purpose case housing and carrying case.
