Images are for illustration purposes only. E&OE Overview The Fluke 1550C performs digital insulation testing up to 5 kV, and makes data collection easy through the Fluke Connect™ wireless app. Remote operation lets you spend as little time as possible in potentially hazardous zones. Real-time trending shows a live graph on your phone, rather than a hard-to-read set of changing values. And you can create reports quickly, using pre-designed templates that you can customize with company logos. It’s the perfect tool for preventive or predictive maintenance programs designed to identify potential equipment failures before they occur. And it comes with a three-year warranty and CAT IV 600 V safety rating. Features Automatic calculation of Dielectric Absorption (DAR) and Polarization Index (PI) with no additional setup Guard system eliminates the effect of surface leakage current on high-resistance measurements Selectable test voltages in 50 V steps from 250 V to 1000 V, and 100 V steps above 1000 V CAT III 1000 V, CAT IV 600 V safety rating Warning function alerts the user that line voltage is present and gives the voltage reading up to 600 V AC or DC for increased user safety Measurements can be stored in up to 99 memory locations, with each location assigned a unique, user defined, label for easy recall Long battery life gives the user over 750 tests between charges Large digital/analog LCD for easy viewing Capacitance and leakage current measurement Ramp function for breakdown testing Resistance measurements up to 2 TΩ Timer settings up to 99 minutes for timed tests 3-year warranty Specifications Insulation Resistance Measurement Test voltage (DC) 250 V Range < 250 kΩ,250 kΩ to 5 GΩ5 GΩ to 50 GΩ> 50 GΩ Accuracy (± reading) Unspecified5%20%Unspecified 500 V Range < 500 kΩ500 kΩ to 10 GΩ10 GΩ to 100 GΩ> 100 GΩ Accuracy (± reading) Unspecified5%20%Unspecified 1000 V Range < 1 MΩ1 MΩ to 20 GΩ20 GΩ to 200 GΩ> 200 GΩ Accuracy (± reading) Unspecified5%20%Unspecified 2500 V Range < 2.5 MΩ2.5 MΩ to 50 GΩ50 GΩ to 500 GΩ> 500 GΩ Accuracy (± reading) Unspecified5%20%Unspecified 5000 V Range < 5 MΩ5 MΩ to 100 GΩ100 GΩ to 1 TΩ> 1 TΩ Accuracy (± reading) Unspecified5%20%Unspecified Bar graph range 0 to 1 TΩ (1550C) - 0 to 2 TΩ (1555) Insulation test voltage accuracy -0%, +10% at 1 mA load current Induced AC mains current rejection 2 mA maximum Charging rate for capacitive load 5 seconds per μF Discharge rate for capacitive load 1.5 s/μF Leakage current measurement Range 1 nA to 2 mA Accuracy ± (5% + 2 nA) Capacitance measurement Range 0.01 μF to 15.00 μF Accuracy ± (15% rdg + 0.03 μF) Timer Range 0 to 99 minutes Resolution setting 1 minute Resolution indication 1 second Live circuit warning Warning range 30 V to 660 V AC/DC, 50/60 Hz Voltage accuracy ± (15% + 2 V) Software specifications FlukeView Forms™ basic software requires a PC running Windows XP, Windows Vista , Windows 7 or Windows 8.
