Digital Multimeter DM90E

DM90E professional digital multimeter can measure voltages up to 600V by simply connecting the input terminals. It meets the requirements of professionals for manually adjusted resistance measurements. It is designed to comply with the EN61010-2-033 safety standard and has CAT Ⅲ 600V insulation protection. The multimeter DM90E is equipped with a white light flashlight, a non-contact AC voltage detection probe, and data logging functions. 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.
