{"product_id":"ermenrich-test-dm90-digital-multimeter","title":"Ermenrich Test DM90 Digital Multimeter","description":"\u003cp\u003eThe Ermenrich Test DM90 digital multimeter is built for demanding measurement tasks in industrial and residential settings. It suits electricians, commissioning engineers, and equipment repair specialists. The model supports True RMS, which matters when working with non-sinusoidal signals. It also has a bar graph to spot fluctuating or trending readings at a glance. The device measures voltage, current, resistance, capacitance, frequency, and temperature. It can also hold readings on the display and capture peak, minimum, and maximum values.\u003c\/p\u003e\n\u003cp\u003eDC and AC voltage are measured up to 1000V. This is enough for residential and industrial power systems, including distribution sections, switchboards, three-phase lines, and power equipment where high voltages are present. Current measurement up to 10A lets you monitor load consumption and check the power circuits of most devices and assemblies. Resistance ranges from 400Ω to 40MΩ are used to check conductors and contacts, assess leakage, and evaluate high-resistance components. Capacitance measurement from 4nF to 40mF suits both small capacitors in electronics and larger ones, such as those in power supplies and start\/filter circuits. Temperature is measured with a K-type thermocouple from −50°C to +760°C. This is suitable for monitoring the heating of terminals, components, heat sinks, motors, and other components during diagnostics. The frequency meter, with ranges up to 10MHz, lets you check mains frequency, generator output, and pulse circuits.\u003c\/p\u003e\n\u003cp\u003eThe continuity buzzer sounds at resistances below 35Ω, speeding up continuity checks and open circuit tracing, while the diode test quickly verifies that semiconductor components are good. The meter takes 2 readings per second and supports auto-ranging. Power comes from a 9V 6F22 battery, which provides up to 85 hours of operation. Auto power off after 30 minutes of inactivity conserves battery life. The 4000-count display is backlit, which makes readings easier to see in low light. The housing, made of ABS plastic, polycarbonate, and thermoplastic elastomer, is designed for regular and intensive use.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eVoltage measurement up to 1000V and current up to 10A with True RMS support\u003c\/li\u003e\n\u003cli\u003eExtended functionality: resistance up to 40MΩ, capacitance up to 40mF, and frequency up to 10MHz\u003c\/li\u003e\n\u003cli\u003eTemperature measurement with a K-type thermocouple from −50°C to +760°C\u003c\/li\u003e\n\u003cli\u003eAuto-ranging, data hold, peak and max\/min capture\u003c\/li\u003e\n\u003cli\u003eAudible continuity test (beeps below 35Ω) and diode test for circuit diagnostics\u003c\/li\u003e\n\u003cli\u003eUp to 85 hours of operation on a single battery, 4000-count backlit display\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\u003eThermocouple\u003c\/li\u003e\n\u003cli\u003ePouch\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\u003e5905555028644\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage size (LxWxH)\u003c\/td\u003e\n\u003ctd\u003e20x13x7 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShipping Weight\u003c\/td\u003e\n\u003ctd\u003e0.66 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, capacitance meter, frequency meter, ohmmeter, thermocouple, voltmeter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDC voltage measuring limit\u003c\/td\u003e\n\u003ctd\u003e400mV\/4V\/40V\/400V: accuracy ±(0.5%+2);
