{"product_id":"ermenrich-test-dm40-digital-multimeter","title":"Ermenrich Test DM40 Digital Multimeter","description":"\u003cp\u003eThe Ermenrich Test DM40 is a compact and practical measuring tool for electrical and electronics work. It comes in handy for electricians, service technicians, and diagnostic specialists. Combining a voltmeter, ammeter, and ohmmeter in one device, it also features a non-contact NCV sensor that detects voltage with no physical contact. Auto-ranging simplifies measurements, and the max hold function captures the highest reading during a test.\u003c\/p\u003e\n\u003cp\u003eThe multimeter measures DC and AC voltage up to 600V, so it is suitable for testing batteries, power supplies, wall outlets, and sections of wiring. It also measures DC and AC current up to 200mA and resistance up to 20MΩ. This makes the meter convenient for monitoring current draw in electronic and low-power circuits as well as checking whether wires, contacts, fuses, windings, and resistors are working properly. The device detects polarity automatically, so if the test leads are connected in reverse, a minus sign appears in front of the reading.\u003c\/p\u003e\n\u003cp\u003eIt also features a dedicated continuity mode, in which the multimeter beeps when the resistance of the section under test drops below approximately 100Ω. This is handy for quickly locating open circuits and poor connections. Diode testing is also supported. It lets you check whether diodes are functional and measure their voltage drop.\u003c\/p\u003e\n\u003cp\u003eThe meter runs on a single 12V 23A battery, with a rated battery life of up to 80 hours. Auto power off saves energy when the meter is left idle, and the low battery indicator lets you know in advance when it is time to replace the battery. The 2000-count display updates readings twice per second. The ABS plastic housing with thermoplastic elastomer inserts is built to withstand everyday use.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e3 core functions in one device: voltmeter up to 600V, ammeter up to 200mA, and ohmmeter up to 20MΩ\u003c\/li\u003e\n\u003cli\u003eNCV (non-contact voltage) detection with LED indication to locate live wires\u003c\/li\u003e\n\u003cli\u003eAuto-ranging enables quick diagnostics without manual range switching\u003c\/li\u003e\n\u003cli\u003eDiode test, continuity test, and max hold to capture the highest readings\u003c\/li\u003e\n\u003cli\u003eUp to 80 hours of operation on a single battery\u003c\/li\u003e\n\u003cli\u003eDurable ABS plastic and thermoplastic elastomer housing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eThe kit includes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDigital multimeter\u003c\/li\u003e\n\u003cli\u003eTest leads\u003c\/li\u003e\n\u003cli\u003eUser manual and warranty card\u003c\/li\u003e\n\u003c\/ul\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eErmenrich\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003e5 years\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEAN\u003c\/td\u003e\n\u003ctd\u003e5905555028613\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage size (LxWxH)\u003c\/td\u003e\n\u003ctd\u003e17x11x2 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShipping Weight\u003c\/td\u003e\n\u003ctd\u003e0.2 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSelection of the measuring limit\u003c\/td\u003e\n\u003ctd\u003eautomatic\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBasic functions \u003c\/td\u003e\n\u003ctd\u003eammeter, ohmmeter, voltmeter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDC voltage measuring limit\u003c\/td\u003e\n\u003ctd\u003e200mV: accuracy ±(0.5%+4); 2V\/20V\/200V: accuracy ±(1.2%+2); 600V: accuracy ±(1.5%+2)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAC voltage measuring limit\u003c\/td\u003e\n\u003ctd\u003e2V: accuracy ±(1.2%+4); 20V\/200V: accuracy ±(1.5%+3); 600V: accuracy ±(2.0%+4)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDC current measuring limit\u003c\/td\u003e\n\u003ctd\u003e200µA\/2000µA: accuracy ±(1.0%+3); 20mA\/200mA: accuracy ±(1.5%+3)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAC current measuring limit\u003c\/td\u003e\n\u003ctd\u003e200µA: accuracy ±(1.5%+3); 2000µA\/20mA\/200mA: accuracy ±(1.8%+3)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eResistance measuring limit\u003c\/td\u003e\n\u003ctd\u003e200Ω: accuracy ±(1.5%+4); 2kΩ: accuracy ±(1.2%+2); 20kΩ\/200kΩ\/2MΩ: accuracy ±(1.5%+2); 20MΩ: accuracy ±(2.0%+3)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMeasurements per second\u003c\/td\u003e\n\u003ctd\u003e2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWire mapping\u003c\/td\u003e\n\u003ctd\u003eyes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eContinuity test\u003c\/td\u003e\n\u003ctd\u003e+\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiodes test\u003c\/td\u003e\n\u003ctd\u003eyes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiode test\u003c\/td\u003e\n\u003ctd\u003e+, test current 0.3mA, open-circuit voltage 1.5V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNon-contact voltage detection (NCV)\u003c\/td\u003e\n\u003ctd\u003eyes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eThroughput capacitance\u003c\/td\u003e\n\u003ctd\u003e50–60Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLimit value function (Min\/Max)\u003c\/td\u003e\n\u003ctd\u003e+ (maximums only)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVoltage polarity detection\u003c\/td\u003e\n\u003ctd\u003eyes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDisplay\u003c\/td\u003e\n\u003ctd\u003eLCD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDisplay counts\u003c\/td\u003e\n\u003ctd\u003e2000\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDisplay digits \u003c\/td\u003e\n\u003ctd\u003e3 1\/2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLight alert\u003c\/td\u003e\n\u003ctd\u003eyes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSafety standards\u003c\/td\u003e\n\u003ctd\u003eclass 2, EN 61010-1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOvervoltage category\u003c\/td\u003e\n\u003ctd\u003ecat.
