Fluke Fluke 1503 Insulation Resistance Tester

The Fluke high-voltage digital megohmmeter is an insulation tester with preset and adjustable test voltages for measuring insulation resistance to 1TΩ (2TΩ for 10kV models) to indicate the condition of windings or cables in motors, switchgears, electrical installations, and other insulated equipment, and it also measures leakage current to 2 milliamperes (mA), capacitance to 20μF, and AC and DC voltage to 600V, signaling when a voltage greater than 30V is detected. In addition to the preset test voltages of 250V, 500V, 1,000V, 2,500V, 5,000V, plus 10,000V for the 10kV models, test voltages can be adjusted in 50V increments to 1,000V and 100V increments above 1,000V. Its PI/DAR (polarization index/dielectric absorption rate) function automatically calculates PI and DAR, which are measurements over time that give a truer indication of insulation condition than single-point measurements. The meter can perform timed tests up to 99 minutes, adjustable in 1-minute increments, and has storage for up to 99 test re...
