Digital insulation testing up to 5000 volts

The Fluke 1550B is a digital insulation tester capable of testing switchgear, motors, generators and cables at up to 5000 V DC. It can be used for a wide range of tests: from simple spot checks to timed tests and breakdown tests. Measurement storage and PC interface software make it ideal for preventive maintenance. Heavy-duty leads, probes and alligator clips fit in the custom carrying case, for a rugged field testing kit.

Test voltages of 250V, 500 V, 1000 V, 2500 V, and 5000 V

Capable of testing in 50V increments between 250V and 1000V and 100V increments between 1000V and 5000V

Measures 0 to 1 Tera-Ohm

Warning voltage function alerts the user that line voltage is present and gives the voltage reading up to 600 V AC or DC

Guard system eliminates the effect of surface leakage current on high-resistance measurements
