the model of the clamp is uni t ut 201. but it only has the scale of 2 / 20A and 200 / 400A the issue that does not mark me if it is direct current or alternating
According to a Join sheet, it serves to continue, but as I said before, the measurement is about the consumption of the vehicle, not the battery amps.
If you pay attention to the battery label it says, for example, 65 amperes and 590 AC or EN. those 590 are the amperes that your battery can deliver in a little high consumption as it is at the start of the vehicle. The higher that number, the more battery quality, in leading brands, the rest is usually a liar.
If you want to measure only the consumption of the aumotivil, use a serial tester that connects it in the battery's output cable to the car's instrumetal. On the DC ampere scale, testing from the highest consumption and going down to a good lectyra
Your clamp does not work to measure DC direct current in amperes. with the press system
