  • Test, power, and diagnose electrical circuits with voltage, resistance, AC, frequency, Power Feed, and fuel-injector testing capabilities.
  • Work through common diagnostic procedures with built-in guidance, including battery, charging, fuse, component, and wiring tests.
  • Capture, review, and share diagnostic data using Trace Mode and the connected Power Probe Pro Series app.
Product description

The Power Probe® Maestro has the ability to communicate with the Power Probe® App, making the diagnostic potential of this tool unlimited. Working in conjunction with the app, the Maestro allows the user to data-log either screenshots or record visual traces of their customer’s electrical issues. The Maestro will have the ability to display an oscilloscope type measurement. In addition to the multimeter functions, guided diagnostics, testing of fuel-injectors, and the ability to apply battery-supplied power and ground, the Maestro and Power Probe® App will be compatible to blend with a majority of diagnostic scan tools out in the market today.

Guided diagnostics

Follow built-in test procedures for common electrical problems and compare results against expected conditions. Guided Diagnostics walks technicians through battery, charging, fuse, component, and wiring tests and reports results such as OK, LOW, HIGH, or CHECK.

Live Trace Mode

Turn electrical signals into an on-screen trace to spot changes, spikes, and intermittent events that a single voltage reading can miss. Trace functionality is available for DC voltage, AC voltage, frequency, and injector testing, giving technicians a more visual view of circuit behavior.

Connected diagnostic data

Pair the Maestro with the Power Probe Pro Series app to mirror the tool display, log diagnostic data, review previous events, save captures, and share results. The app can buffer collected data so technicians can scroll back to an event, isolate a trace, and save it as an image or playback.
