The voltage of the induction cooker ob2226 chip can be measured by the voltage measurement function in the multimeter. First of all, the voltage gear of the multimeter is adjusted to the DC voltage gear, and then the red pen of the multimeter is connected to the positive pole of the chip voltage test point, and the black pen is connected to the negative pole of the chip voltage test point. Then the value of the chip voltage will be displayed on the multimeter. It should be noted that when measuring the voltage of the induction cooker ob2226 chip, the power supply should be disconnected and the capacitor should be discharged before operation to avoid safety problems such as electric shock.
