• Save time by seeing voltage and current measurements at the same time
• Visual Continuity™ – the screen automatically turns green for continuity, perfect when it’s too loud to hear the beeper
• FieldSense™ technology for ac voltage, current and frequency, all without making electrical contact to live voltage

• Non-contact voltage detection from 90 to 1000 V AC
• Innovative 'Battery Check' ensures battery is in good condition*
• Integrated clip design, optimized for pocket storage

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

Key Features
• A rugged, compact insulation resistance tester for residential and commercial electricians
• Performs insulation tests from 0.01 MΩ to 2000 MΩ
• Offers two insulation test voltages: 500 V and 1000 V
• Includes live circuit detection to prevent insulation test if voltage >30 V is detected
• Measures resistance from 0.01 Ω to 20.00 kΩ

• Be aware of voltage easily - the tip glows red and a beeper sounds when voltage is detected
• Continuous self-test so you always know it’s working
• Voltage detection range for wide application use - 90 V to 1000 V AC or 200 V to 1000 V AC
• Audible/Silent mode for added convenience
