TRMS Smart Digital Multimeter DM97S

DM97S is a smart digital multimeter with 10,000 counts and smart range. It supports K-type thermocouple temperature measurement and can easily switch temperature units. DM97S also has a fast diode test function. It complies with the IEC61010-1 safety standard to ensure safety during use. DM97S supports continuity measurement and has sound and light alarm functions. It provides accurate measurement results to help professional electricians improve work efficiency. 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.
