Precision Multimeter With LED Alert DM100

DM100 is a professional TRMS multimeter designed for precise and efficient electrical measurements. It has a clear 10,000-count display and supports AC/DC voltage and current testing with true RMS accuracy. The device can measure ranges from microampere DC current to 1000V DC voltage and 750V AC voltage. With continuity test functions (with sound and LED alarms), diode check, and capacitance up to 10mF, the DM100 is ideal for electricians, HVAC work, and general diagnostics. At the same time, the DM100 can also be equipped with an optional K-type thermocouple to support temperature measurement. It meets the IEC61010-1:2020 CAT III 1000V safety standard and is powered by two AA batteries. The rugged body and intuitive layout ensure easy use in any environment. Frequently Asked Questions Why does my multimeter show “OL” or “1”? When your multimeter displays “OL” (Over Limit) or “1”, it usually means the measurement exceeds the selected range or the circuit is open. For example, if you’re measuring resistance and the probes aren’t touching anything (or measuring an open circuit), your multimeter will show “OL” or “1” to indicate that the value is out of range. Switching to a higher range or reconnecting the probes usually resolves the issue. Yes, many digital multimeters come with a built-in temperature measurement function. These models typically include a K-type thermocouple probe that allows you to measure temperatures in Celsius or Fahrenheit. Check your multimeter’s specifications to see if it supports this feature. It’s especially useful for HVAC technicians or electronics troubleshooting.
