Tips: How to measure the temperature by using a clamp meter?
Do not enter a voltage higher than 60V DC or 30V AC in temperature measurement function to avoid human body damage or clamp meter damage.
- Turn the switch to the temperature measurement position and select (press 'SEL') Celsius or Fahrenheit as required.
- Connect the negative terminal (black) and the positive terminal (red) of the K type thermocouple to the COM input jack and temperature input jack separately.
- The other end of the thermocouple (test side) close to the surface of the measured object.
- The measured temperature value will be read by the LCD display.
Note: The highest measurement temperature of K-type thermocouple in accessory is 250 ℃ (482℉).
