Fluke Insulation Tester

Description

Comply with IEEE 43 motor testing guidelines and NETA acceptance testing specs by certifying insulation resistance on industrial machinery before power startup. The Fluke Digital Insulation Resistance Tester provides test voltages up to one thousand volts to detect breakdown in motor windings and switchgear cables. Millwrights identify moisture ingress and insulation aging before high-voltage flashovers occur. High-capacitance feeder cables require complete automatic discharge through the meter before disconnecting test probes.

Tough impact-resistant polycarbonate encased in a resilient rubberized holster survives repetitive six-foot drops onto plant floor grating. Internal high-voltage transformers generate stable direct-current test potentials up to 1000V DC without thermal sagging. Powered by four standard AA alkaline batteries, the tool delivers over one thousand individual insulation tests on single-battery complements. The handheld tester weighs 1.2 lbs and measures 8.0 inches by 3.9 inches by 2.0 inches, built for tight motor junction box access.

Insulation Megohm Bench Calibration Limits

Bench calibration testing with high-precision standard resistance decade boxes verifies insulation reading accuracy within 1.5 percent up to two gigohms. The automated ramp test applies 50V, 100V, 250V, 500V, and 1000V DC test levels, maintaining target voltage within ten percent under heavy capacitive motor loading. Live circuit detection logic inhibits testing if terminal voltage exceeds thirty volts, protecting internal megohm bridge circuits from destructive feedback. Thermal drift remains under 0.1 percent per degree Celsius across standard industrial plant temperatures.

Key Features of Fluke 1507

Industrial plant electricians buy Fluke Digital Insulation Resistance Tester units to inspect conveyor motors, dry-type transformers, and electrical bus runs. Compare commercial digital insulation megohmmeter pricing to improve your plant electrical maintenance program.

• Multiple test voltage selections include 50V, 100V, 250V, 500V, and 1000V DC ranges.
• Insulation resistance measurement range reads from 0.01 megohms up to ten gigohms cleanly.
• Automatic calculation of Polarization Index and Dielectric Absorption Ratio saves diagnostic calculation time.
• Remote test probe with integrated test button enables one-handed testing inside deep control cabinets.
• Auto-discharge circuit safely dumps capacitive voltage charges from cables upon test completion.
• Live circuit detection stops test initiation if voltages exceeding thirty volts are detected.

Motor Shop Negative Selection Filter

The remote probe button fires high-voltage test sequences with a simple thumb press, keeping technicians focused on probe tips. Do not buy this 1000-volt megohmmeter for high-voltage transmission cables requiring five-kilovolt or ten-kilovolt hipots, or precision micro-ohm contact resistance testing. Clean silicone test leads with dry shop towels, check internal 1000V fuses before testing, and store the unit inside its case between quarterly motor inspections.
