Description Fluke 1503 Insulation Resistance Tester handles all the basic insulation testing needs The Fluke 1503 is a great choice for basic residential and commercial electrical insulation testing. This rugged, compact tool fits in the palm of your hand. The 1503 is the same form factor as the Fluke 1507 but with a few less features. You can count on it to handle the most common tests at a most affordable price. Additional features, like the remote probe, reduce the time needed to perform repetitive testing. Other useful capabilities: Measures AC/DC voltage from 0.1 V to 600 V Includes auto-discharge of capacitive voltage for added user protection Provides lo-ohms earth-bond continuity (200 mA) Simplifies repetitive or hard-to-reach testing with the remote test probe Saves battery power with auto power off Presents results on a large, backlit display Features CAT IV 600 V overvoltage category rating Comes with remote probe, test leads, test probes, alligator clips, and one-year warranty Accepts optional Fluke TPAK magnetic hanging system to free your hands for other work Runs on four AA alkaline batteries (NEDA 15 A or IEC LR6) for at least 1000 insulation tests Specifications: Fluke 1503 Insulation Resistance Meter AC/DC Voltage Measurement Accuracy Range 600.0 V Resolution 0.1 V 50 Hz to 400 Hz ±(% of Rdg Digits) ±(2% 3) Input impedance 3 MΩ (nominal), < 100 pF Common mode rejection ratio (1 kΩ unbalanced) > 60 dB at DC, 50 or 60 Hz Overload protection 600 V rms or DC Earth Bond Resistance Measurement Range/Resolution 20.00 Ω 0.01 Ω 200.0 Ω 0.1 Ω 2000 Ω 1.0 Ω 20.00 kΩ 0.01 kΩ Accuracy ±(1.5% 3) Overload protection 2 V rms or DC Open circuit test voltage > 4.0 V, < 8 V Short circuit current > 200.0 mA Insulation Specifications Measurement range 0.01 MΩ to 2000 MΩ Test voltage 500 V, 1000 V Test voltage accuracy 20%, – 0% Short circuit current 1 mA nominal Auto discharge Discharge time < 0.5 second for C = 1 µF or less Live circuit indicator Inhibit test if terminal voltage > 30 V prior to initialization of test Maximum capacitive load Operable with up to 1 µF load Measure accuracy 500 V ±(1.5% 5) 1000 V ±(1.5% 5) to 2000 MΩ, ±(10% 3) above 2000 MΩ General Specifications Maximum voltage applied to any terminal: 600 V AC rms or DC Storage temperature -40°C to 60°C (-40°F to 140°F) Operating temperature -20°C to 55°C (-4°F to 131°F) Temperature coefficient 0.05 x (specified accuracy) per °C for temperatures < 18°C or > 28°C (< 64°F or > 82°F) Relative humidity 0% to 95% @ 10°C to 30°C (50°F to 86°F) 0% to 75% @ 30°C to 40°C (86°F to 104°F) 0% to 40% @ 40°C to 55°C (104°F to 131°F) Vibration Random, 2 g, 5-500 Hz per MIL-PRF-28800F, Class 2 instrument Shock 1 meter drop per IEC 61010-1 2nd Edition (1 meter drop test, six sides, oak floor) Electromagnetic compatibility In an RF field of 3 V/M, accuracy = specified accuracy (EN 61326-1:1997) Safety Complies with ANSI/ISA 82.02.01 (61010-1) 2004, CAN/CSA-C22.2 NO. 61010-1-04, and IEC/EN 61010-1 2nd Edition for measurement category IV 600 V (CAT IV) Certifications CSA per standard CSA/CAN C22.2 No. 61010.1-04; TUV per standard IEC/EN 61010-1 2nd Edition Batteries Four AA batteries (NEDA 15A or IEC LR6) Battery llife Insulation test use: Tester can perform at least 1000 insulation tests with fresh alkaline batteries at room temperature.
