You can use buzzer to measure the quality of induction cooker chip.
Induction cooker chip is a high frequency electromagnetic field element in induction cooker, its quality directly affects the use effect of induction cooker. The following is the correct measurement method of induction cooker chip:
< br >
1. Remove the induction cooker chip from the induction cooker and clean the dirt and oil stains on the surface.
< br >
2. Use a multimeter to test the resistance of the chip. Set the multimeter to the resistance gear and measure the resistance at both ends of the chip. If the resistance value of the chip is not within the specified range, there is a problem with the chip.

3. Use a magnetometer to test the magnetic field strength of the chip. Before testing, the magnetometer needs to be calibrated to zero, and then the chip is placed on the sensor of the tester so that it is in the middle position. Record the magnetic field strength value on the display screen of the tester to determine whether it meets the specified value.

4. Through visual inspection, carefully observe whether there are cracks, defects, deformation and other problems on the chip surface. If an exception is found, the chip needs to be replaced.

In general, the combination of the above three methods can more accurately detect the quality and performance of the induction cooker chip to ensure the normal use of the induction cooker.
