The Fluke 1507 and 1503 insulation testers are handy, robust, reliable and easy to use. Since they have multiple test voltages, they are ideal for troubleshooting, set-up and preventative maintenance. - Insulation testing range: 0.1 Mohm to 2000 Mohm - Insulation testing voltages: 500 V, 1000 V - A probe with release button makes repetitive tests or tests on hard-to-reach objects easier - Detection of live circuits prevents insulation tests at voltages over 30 V and thus increases the protection of the user - Automatic discharge of capacitive voltages for higher protection for the user - AC/DC voltage: 0.1 V to 600 V - 200 mA continuity - Resistance: 0.01 ohm - 20.00 kohm - Automatic shut-off to save battery power - Large backlit display for easy reading of measurements - Overvoltage category CAT IV 600 V for increased protection of the user - Probe with release button, test leads, test probes and crocodile clips included - Mounting options for the optional magnet holder Fluke TPAK for hands-free operation - Four alkaline batteries type AA (NEDA 15 A or IEC LR6) for more than 1000 insulation tests AC and DC voltage measurement Inaccuracy Range: 600.0 V Resolution: 0.1 V 50 Hz to 400 Hz ± (% of MW + digits) ±(2% + 3) Input impedance: 3 Mohm (nominal), < 100 pF Common-mode rejection ratio (1 kohm unbalanced): > 60 dB at DC, 50 Hz or 60 Hz Overload protection: 600 V effective or DC Protective conductor resistance measurement Range/resolution: 20.00 ohm 0.01 ohm 200.0 ohm 0.1 ohm 2000 ohm 1.0 ohm 20.00 kohm 0.01 k ohm Inaccuracy: ±(1.5% + 3) Overload protection: 2 V effective or DC Idle test voltage: > 4.0 V, < 8 V Short-circuit current: > 200.0 mA Measuring and test functions Measuring range: 0.01 Mohm up to 2000 Mohm Test voltages: 500 V, 1000 V Inaccuracy of the test voltage: + 20%, - 0% Short-circuit current: 1 mA nominal Automatic discharge: discharge time < 0.5 seconds at C = 1 µF or less Display for power circuit: prevents the test if external voltage before the beginning of the tests > 30 V Maximum capacitive load: can be operated with up to 1 µF load Inaccuracy when measuring: 50 V: ±(3% + 5) 100 V: ±(3% + 5) 250 V: ±(1.5% + 5) 500 V: ±(1.5% + 5) 1000 V: ±(1.5% + 5) up to 2000 Mohm, ±(10% + 3) over 2000 Mohm Included with delivery TP165x slim probe with release button TL224 SureGrip silicon test lead set TP74 probes with pointed 4 mm banana plugs Crocodile clips User manual 4 AA batteries https://elecena.pl/product/18013659/2427883-fluke-insulation-tester-1503 2021-04-29 https://elecena.pl/product/18013659/2427883-fluke-insulation-tester-1503 2021-10-05 https://elecena.pl/product/18013659/2427883-fluke-insulation-tester-1503 2021-10-28 https://elecena.pl/product/18013659/2427883-fluke-insulation-tester-1503 2022-02-15 https://elecena.pl/product/18013659/2427883-fluke-insulation-tester-1503 2022-03-17 https://elecena.pl/product/18013659/2427883-fluke-insulation-tester-1503 2022-08-21 https://elecena.pl/product/18013659/2427883-fluke-insulation-tester-1503 2022-10-19 https://elecena.pl/product/18013659/2427883-fluke-insulation-tester-1503 2023-05-07 https://elecena.pl/product/18013659/2427883-fluke-insulation-tester-1503 2023-10-23 https://elecena.pl/product/18013659/2427883-fluke-insulation-tester-1503 2024-04-24 https://elecena.pl/product/18013659/2427883-fluke-insulation-tester-1503 2025-02-08 https://elecena.pl/product/18013659/2427883-fluke-insulation-tester-1503 2025-04-08 https://elecena.pl/product/18013659/2427883-fluke-insulation-tester-1503 2025-05-24 https://elecena.pl/product/18013659/2427883-fluke-insulation-tester-1503 2025-06-04 https://elecena.pl/product/18013659/2427883-fluke-insulation-tester-1503 2026-03-04
