{"product_id":"ermenrich-test-dm20-digital-multimeter","title":"Ermenrich Test DM20 Digital Multimeter","description":"\u003cp\u003eThe Ermenrich Test DM20 is a compact digital multimeter for household and professional work. It is a good fit for auto electricians, electronics repair technicians, and home users. The meter combines a voltmeter, ammeter, and ohmmeter with a non-contact NCV voltage detector that alerts you with vibration and an LED. This kind of alert is especially useful in noisy rooms or outdoors.\u003c\/p\u003e\n\u003cp\u003eThe DM20 measures DC voltage on ranges from 200mV to 500V and AC voltage on the 200V and 500V ranges. That covers the usual jobs: testing batteries and rechargeable cells, diagnosing control circuits, and checking household mains. DC current is available on the 2000µA and 200mA ranges, which suits sensor and circuit board testing. Resistance ranges from 200Ω to 2000kΩ let you check the continuity of wires, windings, and heating elements and track down open and short circuits. The meter takes 2 readings per second.\u003c\/p\u003e\n\u003cp\u003eThe diode test checks a semiconductor junction by its forward voltage drop. There is also a hold function that freezes the current reading on screen, and an audible alert in NCV mode. Polarity is detected automatically and negative values are shown with a minus sign, so you get a correct reading even if the leads are swapped. The meter has a 9V battery test mode. Unlike a simple voltage measurement, it gives a more accurate indication of how much charge the battery has left.\u003c\/p\u003e\n\u003cp\u003eThe meter runs on a 12V 23A battery, good for about 80 hours of continuous use. The ABS plastic housing with a thermoplastic elastomer coating is rated for humidity up to 70% and temperatures from 0°C to +50°C. The 2000-count display is easy to read. \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eVoltmeter, ammeter, and ohmmeter in a compact housing\u003c\/li\u003e\n\u003cli\u003eVoltage up to 500V and current up to 200mA for diagnosing household and automotive circuits\u003c\/li\u003e\n\u003cli\u003eNon-contact NCV detector with vibration and LED alerts\u003c\/li\u003e\n\u003cli\u003eResistance up to 2MΩ, diode test, 9V battery test, and data hold\u003c\/li\u003e\n\u003cli\u003eUp to 80 hours on a single battery; low battery indicator\u003c\/li\u003e\n\u003cli\u003eAutomatic polarity detection with minus sign indication\u003c\/li\u003e\n\u003cli\u003eABS 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\u003e5905555028651\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\u003e0.19 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSelection of the measuring limit\u003c\/td\u003e\n\u003ctd\u003emanual\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\/2000mV\/20V\/200V: accuracy ±(0.5%+2); 500V: accuracy ±(0.5%+4)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAC voltage measuring limit\u003c\/td\u003e\n\u003ctd\u003e200V\/500V: accuracy ±(1.2%+10)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDC current measuring limit\u003c\/td\u003e\n\u003ctd\u003e2000µA: accuracy ±(1.2%+2); 200mA: accuracy ±(1.5%+2)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eResistance measuring limit\u003c\/td\u003e\n\u003ctd\u003e200Ω\/2000Ω\/20kΩ\/200kΩ: accuracy ±(0.8%+4); 2000kΩ: accuracy ±(1.5%+2)\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\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 1.0mA, open-circuit voltage 2.8V 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\u003eHold function\u003c\/td\u003e\n\u003ctd\u003eyes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBattery test\u003c\/td\u003e\n\u003ctd\u003eyes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBattery test\u003c\/td\u003e\n\u003ctd\u003e9V\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\u003eEN 61010-1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOvervoltage category\u003c\/td\u003e\n\u003ctd\u003ecat.
