Product Introduction
3. Common problems and solutions
(1) Inaccurate current display
If it is a direct or independent power supply and the equipment power supply are grounded, simply disconnect the thin black wire to achieve accuracy.
(2) No display when connected to the power supply
Any AC power that has been rectified must be filtered by an electrolytic capacitor with a capacitance of at least 1000uF before it can be supplied to the meter head.
Product Note
Be careful:
(1) The power supply voltage of the meter head must be 4-30V, and if it exceeds 30V, it needs to be independently powered and wired according to the diagram.
(2) Current detection range: 0~5A, maximum detection current cannot exceed 5A
(3) When testing the current of 5A, the wire (thick wire) can be directly soldered onto the 2PIN current detection terminal on the module.
