Intelligent Multimeter DM97S+

DM97S+ is a smart continuity multimeter with a high-precision 10,000-count display and a vivid color screen. It features intelligent auto-ranging for seamless electrical measurements and supports temperature readings via a K-type thermocouple with °C/°F switching. Designed for fast diode testing and circuit diagnostics, the DM97S+ ensures safe operation with IEC61010-1 compliance—making it ideal for professional, accurate, and efficient electrical work. 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.
