Cara Menguji Elemen Pemanas Inframerah dengan Multimeter

There are many standards to evaluate the quality of heating elements. How can we simply test the quality of a heating element in our daily work and life? Today, I will share with you how to use a multimeter to test the quality of a heating element.

Set the multimeter to the 1K ohm range, and place the two probes on both ends of the heating wire.

If the multimeter displays a certain value, it means the heating wire is functioning normally. Take note of the resistance value. If no value is displayed, it indicates that the heating wire has a break, and the heating element cannot be used.

By using the formulas 220250/resistance value or 380380/resistance value, you can calculate the power. If the calculated power deviates by less than 5% from the rated power, the heating element is good.

If the power deviation is large, it indicates that the manufacturing process is substandard. If the power value is excessively high, such as over 10,000, it means there is a short circuit in the heating wire, which could lead to a fire or other electrical malfunctions. In this case, the heating element should not be used.
