Cordless Circuit Tester 7760

The Astro Pneumatic 7760 is a battery powered voltmeter for 3-28V DC circuits. It uses the operator's body as the ground reference so no separate ground cable or clamp is required. The V-Tip design allows safe and centred wire piercing without damaging insulation. It is rated safe for use on ECMs, transducers and airbag systems.

Check Before Ordering

You must hold the tester while simultaneously contacting a ground point with bare skin for the circuit to complete. Verify the system voltage falls within the 3-28V DC range before testing. This tool is not suitable for AC mains voltage or for circuits outside the stated DC window. Ensure you can safely reach both the probe point and a ground contact while working.

Build And Daily Use

The compact housing measures 6.6 L x 1.6 W x 0.9 H inches and weighs 0.1 pounds for easy one-hand operation. UL, CE and IEC markings confirm compliance with recognised safety standards. Battery power removes the inconvenience of trailing ground leads around the vehicle. The cordless design speeds up routine checks on lighting, sensors and accessory circuits.
