The BT-39K is an auto-ranging meter built around a 4000-count display with true RMS measurement, which means it reads a distorted waveform as the equivalent heating value rather than as a number that is quietly wrong on anything other than a clean sine wave.\u003c\/p\u003e\n\u003cp style=\"font-size:16px;line-height:1.85;color:#333;margin:0 0 18px;\"\u003eAuto-ranging is not a convenience feature on a bench meter, it is a safety feature. Manual meters invite the mistake of measuring mains voltage on a resistance range, and that mistake destroys the instrument and occasionally the person holding it. Here the meter selects the range, and the input is protected against overload with a fused current path and a high-energy resistor on the voltage input.\u003c\/p\u003e\n\u003cp style=\"font-size:16px;line-height:1.85;color:#333;margin:0 0 18px;\"\u003eThe display is backlit with a data-hold function and a continuity beeper fast enough to trace a harness without watching the screen. Capacitance, diode test, frequency and duty cycle cover the checks that come up in repair work, and the case is moulded with a stand and a hanging hook so it can sit upright on a bench with both hands free for probes.\u003c\/p\u003e\n\u003cp style=\"font-size:16px;line-height:1.85;color:#333;margin:0 0 18px;\"\u003eIt arrives with test leads, a thermocouple for temperature measurement and a case that keeps the probes from being lost between jobs. For anyone doing fault-finding on mains circuits, automotive harnesses, or a bench full of salvaged electronics, this is the meter that stays on the desk rather than in the drawer.\u003c\/p\u003e\n\u003cp style=\"font-size:16px;line-height:1.85;color:#555;margin:0 0 6px;\"\u003e\u003cem\u003eMeasurement you cannot trust is worse than no measurement at
