How to measure the running current of the air conditioner with a clamp ammeter
It's very simple! Make a strip with two power cords separated by yourself, insert the power plug of the air conditioner into your own strip, plug your own strip into the power supply, put one line of the strip into the middle of the clamp of the clamp-type ammeter, and adjust the ammeter to the current After the air conditioner is turned on, the reading on the meter is the operating current of the air conditioner.
How many amps to measure the air conditioner's current to run normally?
The current size of the air conditioner when it is running is directly related to the power of the air conditioner.
Take a "big 1 hp" air conditioner as an example, its power is about 1000W, and the current during cooling is
I = P / V = 1000W / 220V = 4.5A.
There is a nameplate nailed to other air conditioners with different powers, which clearly indicates the power, current and other parameters of the machine.
If the measured operating current is obviously different from the value on the nameplate, for example, it is obviously lower, then the refrigerant of the air conditioner may be seriously insufficient, and the tightness of the copper pipe must be checked and refrigerant needs to be added.
How to measure air conditioner current
Preferably a clamp meter.
Make a power strip with two separate power cords by yourself, and insert the air conditioner power plug into your own power strip.
Plug your own power strip into the power supply, and insert a line of the power strip into the middle of the clamp of the clamp ammeter.
Adjust the ammeter to the current gear, and the reading on the meter after the air conditioner is turned on is the operating current of the air conditioner.

How to measure the working current of the air conditioner with a digital multimeter
1. My red test lead is inserted in the COM hole, and the black one is in the 10A hole. The adjustment is 10A. Is it possible that the adjustment of the meter becomes a wire and a direct short circuit?
Answer: This is basically a wire. When measuring, it needs to be connected in series with the electrical appliance. If the red pen is connected to the live wire hole, then the black pen should be connected to either end of the electrical appliance, and the other end of the electrical appliance is connected to the neutral wire hole. You can directly connect the live wire hole to the neutral wire. A wire hole is equivalent to a short circuit.
2. The original fuse in your home is not necessarily 5A.
