ST181 Digital Clamp Meter - 4000 Counts AC/DC Clamp Multimeter Measures Current, Voltage, Capacitance, Resistance, Frequency | NCV Detection for Electricians

<p>Features：<br>All-in-One Electrical Troubleshooting: This clamp meter is the ideal tool for rapid troubleshooting. Accurately measures AC Current (Clamp-on, non-intrusive), AC/DC Voltage, Resistance, Capacitance, Diode, Continuity, Frequency (Hz), and Live/Zero Wire detection. Greatly improves efficiency in diagnosing vehicle or internal electrical issues.<br>Double Open Clamp for Wider Access: Features a double open jaw design that accommodates wire diameters up to 1.42 inches (36mm) without needing to interrupt the circuit. Meets various operating habits and allows for quick, non-contact current measurement.<br>Non-Contact Voltage (NCV) Safety: The NCV detection function allows you to quickly and safely determine the presence of AC voltage without physical contact. Easily activate the NCV mode by short-pressing the dedicated NCV button in any measurement gear.<br>Durable &amp; Portable Design: Built to withstand demanding, long workdays. Its stylish and protective design prevents damage and scratches from accidental bumps or drops, ensuring the device remains in good condition for traveling or outdoor professional use.</p> <p><br>Specifications:<br>Product Material: ABS<br>Line Material: Brass+PVC<br>Color: Black+Red<br>Power Supply: 2 * AAA Battery (NOT included)<br>Automatic Shutdown: After 15 minutes<br>Display: LCD display<br>Maximum Count: 4000 counts<br>Jaw Opening: 36mm<br>DC Voltage Range: 400mV±(1.5%+5), 4V~600V±(1.0%+3)<br>AC Voltage Range: 4V~600V±(1.5%+3)<br>AC Current Range: 40A~400A±(2.5%+3)&nbsp;<br>Frequency Range: 10Hz-400kHz±(1.0%+5), 400kHz-4MHz±(2.0%+5)<br>Resistance Range: 400Ω±(1.2%+3), 4kΩ~40MΩ±(1.5%+5)<br>Capacitance Range: 1nF~4μF±(2.5%+10), 4μF~400μF±(4.0%+20), 4mF±(5.0%+30)<br>Diode: yes<br>Zero/Fire Line Identification: yes<br>NCV Test: yes<br>On-off Beep: yes<br>Backlight: yes<br>Data Hold: yes</p> <p>&nbsp;</p> <p>Packing List:<br>1 x Clamp Meter<br>4 x Connection Sockets<br>2 x PVC Cables<br>2 x Copper Pins<br>2 x U-Shaped Plugs<br>2 x Meter Pens<br>4 x Alligator Clips<br>2 x Puncture Needles<br>2 x Test Leads<br>1 x Instruction Manual<br>1 * Storage Bag</p>
