It runs off the measured circuit (no separate power supply needed), includes a flexible current transformer (CT) for convenient placement, and offers a trimmer potentiometer for in-field calibration. The back cover and simple 2-wire connection make installation straightforward and safer for panel mounting.\u003c\/p\u003e\n\n\u003ch3\u003eHow accurate and wide-ranging are the measurements?\u003c\/h3\u003e\n\u003cp\u003eThe DROK meter covers a useful household and industrial AC range: 60–500V for voltage and 0–200A for current. The supplied CT lets you measure higher currents without bulky wiring through the meter body, and the built-in trimmer allows fine-tuning if your readout needs calibration.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eVoltage range: AC 60–500V\u003c\/li\u003e\n  \u003cli\u003eCurrent range: 0–200A via included CT\u003c\/li\u003e\n  \u003cli\u003eCalibrate easily using the built-in trimmer potentiometer\u003c\/li\u003e\n  \u003cli\u003eSeparate color-coded LEDs for immediate clarity\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat does the display show and how easy is it to read?\u003c\/h3\u003e\n\u003cp\u003eThis model uses a dual-color LED display: red numerals for voltage and green for current, so both values are visible simultaneously without switching modes. The 0.39-inch digits are compact but clear for panel use; contrast between the colors helps reduce reading errors in bright or dim environments.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e0.39\" LED digits: red for volts, green for amps\u003c\/li\u003e\n  \u003cli\u003eSimultaneous voltage and current readout\u003c\/li\u003e\n  \u003cli\u003eNo mode toggling — immediate snapshot of the circuit's status\u003c\/li\u003e\n  \u003cli\u003ePanel-mount friendly bezel and covered rear for safety\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow do I install and power the meter?\u003c\/h3\u003e\n\u003cp\u003eInstallation is designed for simplicity: the gauge is powered directly by the measured circuit, so no extra power wire is necessary.
