Fluke Apprentice Diagnostic Kit
October 23, 2026
From quick safety checks to accurate AC/DC measurements and real fault isolation
This kit expands beyond basic safety workflows to give electricians the accuracy needed for true diagnostics. With the Fluke 106, a compact, CAT III 600 V DMM, users can validate AC/DC voltage, check continuity, measure resistance, confirm current behavior, and isolate faults more accurately than with go/no-go tools alone.
Real world applications
- Accurate AC/DC voltage validation: verify supply voltage to motors, lighting circuits, low voltage transformers, HVAC equipment, controls, and power supplies to distinguish between line and load-side faults.
- Continuity and resistance checks for fault isolation: locate opens, shorts, degraded connections, or damaged conductors.
- Outlet and circuit verification: pair ST120+ GFCI testing with DMM readings to confirm wiring accuracy, pair ST120+ GFCI testing with DMM readings to confirm wiring accuracy, detect open ground conditions, and ensure stable voltage delivery under load.
- Panelboard and branch circuit diagnostics: measure voltage drop, detect phase imbalance, verify neutral continuity, and confirm safe operating conditions before deeper work begins.
- Low voltage system checks: ideal for thermostats, security systems, lighting controls, and access devices.
