The RF4 RF-17N brings 6000-count auto-range precision straight to your repair bench. Built for technicians who diagnose dead phones, charging faults, and board-level issues daily, this true-RMS multimeter reads AC/DC voltage, current, resistance, capacitance, diode, continuity, frequency, and temperature from 20°C to 1000°C. Automatic polarity identification and a double-integral A/D transform keep readings stable even on tricky PCB traces. The backlit LCD stays readable in low workshop light, and auto power-off protects battery life during long diagnostic sessions. It's a dependable everyday tool for tracing shorts, checking IC pin voltages, and confirming continuity before you commit to an IC change or jumper wire. Show more
