It measures AC and DC voltage up to 600 volts, AC and DC current up to 10 amps, and resistance, while also handling temperature, capacitance, frequency, and duty cycle readings. The MM400 carries a CAT III 600V safety rating and is built to survive a 3.3-foot drop, making it a dependable daily-use instrument for licensed electricians and HVAC technicians working across a range of field conditions.\u003c\/p\u003e\u003cp\u003eThis multimeter is designed for use in basic controlled electromagnetic environments including residential, business, and light industrial locations. Its auto-ranging function eliminates the need to manually set measurement ranges, reducing setup time during troubleshooting. It also supports diode testing and continuity checks, covering the core diagnostic tasks that electricians, HVAC technicians, and industrial maintenance professionals encounter on a typical service call. The kit ships with test leads, a thermocouple with adapter, and batteries, so it is ready to use out of the box.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAuto-ranging measurement across voltage, current, resistance, capacitance, frequency, and duty cycle\u003c\/li\u003e\n\u003cli\u003e600V AC\/DC voltage range with CAT III 600V safety rating\u003c\/li\u003e\n\u003cli\u003e10A AC\/DC current measurement capability\u003c\/li\u003e\n\u003cli\u003eTemperature measurement via included thermocouple with adapter\u003c\/li\u003e\n\u003cli\u003eDiode testing and continuity check functions built in\u003c\/li\u003e\n\u003cli\u003eSurvives a 3.3-foot drop for durability under daily job-site use\u003c\/li\u003e\n\u003cli\u003eLow battery indicator and easily accessible battery compartment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in basic controlled electromagnetic environments such as residential, business, and light industrial locations where CAT III 600V rated test equipment is appropriate.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by a qualified electrician or licensed technician familiar with safe metering practices. Always de-energize circuits before connecting or disconnecting test leads where permitted by the work procedure, and verify the meter's CAT III 600V rating is appropriate for the circuit under test. Follow applicable NEC guidelines and local codes when performing electrical measurements. Never exceed the rated input limits for any measurement function.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Measurement (AC\/DC)\u003c\/strong\u003e: Up to 600 volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Measurement (AC\/DC)\u003c\/strong\u003e: Up to 10 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunctions\u003c\/strong\u003e: Voltage, Current, Resistance, Temperature, Capacitance, Frequency, Duty Cycle, Diode Test, Continuity\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSafety Rating\u003c\/strong\u003e: CAT III 600V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrop Resistance\u003c\/strong\u003e: 3.3 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 6.2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KLEIN TOOLS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MM400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KLEIN TOOLS","offers":[{"title":"Default Title","offer_id":51523593666866,"sku":"MM400","price":466.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aafb7f28d7933aad14634070947b165e.jpg?v=1785443104","url":"https:\/\/voomisupply.com\/products\/klein-tools-mm400-digital-multimeter-600v-auto-ranging","provider":"Voomi Supply","version":"1.0","type":"link"}
