This tool is for anyone—whether in a camper or in the workshop—who wants to know exactly where the current is flowing.\u003c\/strong\u003e\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eIn a camper setup, DC\u003c\/strong\u003e measurement is the main reason for using this device. You clamp the jaws around the positive cable of the auxiliary battery and immediately see how much power the solar system is feeding into the system, what the charge booster is supplying, how much power the compressor refrigerator is drawing, and where power is still being consumed in standby mode. That’s exactly what most inexpensive clamp meters can’t do—they only measure alternating current. On the 230-V side, you can check shore power cables and CEE extension cords for continuity, measure the voltage at the outlet, and use the non-contact test to locate live wires. With the included K-type probe, you can also measure temperatures—for example, on cable lugs under load, on the heater’s hot-air duct, or inside the refrigerator.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eWhat the abbreviations on the housing mean.\u003c\/strong\u003e \u003cem\u003eTrue RMS\u003c\/em\u003e means that even distorted AC signals—such as those generated by an inverter or a power supply—are displayed correctly; simple average-value meters measure too low in these cases. \u003cem\u003eLoZ\u003c\/em\u003e switches the input to low impedance (1 MΩ instead of 10 MΩ) and eliminates ghost voltages caused by coupling on unconnected wires—so you know whether a line is actually live. \u003cem\u003eVFC\u003c\/em\u003e filters the measurement so that even the output voltage and output current of a frequency converter can be read reliably. \u003cem\u003eNCV\u003c\/em\u003e is the non-contact voltage test starting at around 90 V AC, featuring a buzzer and LED. It also includes display backlighting and an LED work light in the head, both controlled by the same button.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eRegarding safety classification:\u003c\/strong\u003e The MT-3209 is rated at \u003cstrong\u003e600 V CAT II\u003c\/strong\u003e according to IEC 61010. This covers measurements on outlet circuits, devices, and the 12-V vehicle electrical system. For measurements directly at the main distribution panel, on the service line, or at the meter, a CAT III or CAT IV-rated device is required—\u003cstrong\u003ethis clamp meter is not intended for such applications.\u003c\/strong\u003e\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eAt a Glance\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eDisplay: 3 5\/6-digit LCD, max. 6,000 counts, with backlight\u003c\/li\u003e \u003cli\u003eJaw opening: 30 mm\u003c\/li\u003e \u003cli\u003eAC: 60 A \/ 600 A, True RMS, ±(2.5% + 5 digits), 40 Hz–1 kHz\u003c\/li\u003e \u003cli\u003eDirect current: 60 A ±(3.0% + 15 digits) \/ 600 A ±(3.0% + 5 digits)\u003c\/li\u003e \u003cli\u003eDC voltage: 600 mV \/ 6 V \/ 60 V \/ 600 V, input impedance 10 MΩ\u003c\/li\u003e \u003cli\u003eAC voltage: 6 V \/ 60 V \/ 600 V, True RMS\u003c\/li\u003e \u003cli\u003eOpen-loop voltage measurement: 600 V AC\/DC, input impedance 1 MΩ\u003c\/li\u003e \u003cli\u003eResistance: 600 Ω to 60 MΩ · Capacitance: 6 nF to 100 mF\u003c\/li\u003e \u003cli\u003eFrequency: 600 Hz to 600 kHz via voltage, 600 Hz via clamp (6 A and above)\u003c\/li\u003e \u003cli\u003eTemperature: −20 °C to 1000 °C with a K-type probe\u003c\/li\u003e \u003cli\u003eDiode test and continuity tester with buzzer (below approx. 30 Ω)\u003c\/li\u003e \u003cli\u003eAutomatic range selection, data hold, overload protection across the entire measurement range\u003c\/li\u003e \u003cli\u003eAutomatic shut-off after 15 minutes, measurement rate approx. 3×\/s\u003c\/li\u003e \u003cli\u003eSafety: 600 V CAT II per IEC 61010-1 \/ -2-030 \/ -2-032, pollution degree 2\u003c\/li\u003e \u003cli\u003ePower supply: 2× AAA 1.5 V – \u003cstrong\u003enot included\u003c\/strong\u003e \u003c\/li\u003e \u003cli\u003eDimensions: 190 × 71 × 30 mm\u003c\/li\u003e \u003cli\u003ePackage Contents: Current clamp, test leads (1 pair), K-type temperature probe, instruction manual\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eFrequently Asked Questions\u003c\/strong\u003e\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eAre batteries included?\u003c\/strong\u003e\u003cbr\u003eNo. You’ll need 2× AAA (1.5 V) batteries, which you can find at any store. \u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eCan I use it to measure power consumption in a 12-V vehicle electrical system?\u003c\/strong\u003e\u003cbr\u003eYes, that’s what it’s designed for. Important: Always clamp onto only \u003cem\u003eone\u003c\/em\u003e wire at a time; never clamp the positive and negative wires together—otherwise, the fields cancel each other out and you’ll measure zero. And before every DC measurement, use the Hz\/Zero button to set the reading to zero; otherwise, the display will show an offset.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eCan I use it to take measurements in the fuse box?\u003c\/strong\u003e\u003cbr\u003eNo. The clamp meter is rated at 600 V CAT II, which is sufficient for outlet circuits and end devices. CAT III or CAT IV is required for distribution panels and supply lines.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eWhy does a disconnected wire still show voltage?\u003c\/strong\u003e\u003cbr\u003eThese are phantom voltages caused by capacitive coupling from parallel wires. That’s what the LoZ setting is for: It applies a slight load to the input, causing the phantom voltage to drop. If the value remains stable, there is actually voltage present.\u003c\/p\u003e \u003cp\u003e \u003c\/p\u003e","brand":"waerchzueg.ch","offers":[{"title":"Default Title","offer_id":56407723770235,"sku":"MT-3209","price":59.9,"currency_code":"CHF","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0299\/8347\/3708\/files\/202507301119150009.jpg?v=1788770786","url":"https:\/\/www.waerchzueg.ch\/en\/products\/proskit-current-clamp-600-a-ac-dc-true-rms-loz-vfc-ncv-and-temperature-measurement","provider":"waerchzueg.ch","version":"1.0","type":"link"}
