I have an uni t amperometric clamp. and I wanted to measure the amperage given by my car battery. The question is whether the measurement has to be done on the positive or negative battery cable. Thank you

Dear, the amperometric clamp will only measure the consumption of the vehicle, lights, starting, electric fan, etc. As long as it is to measure continuous current consumption, some only measure alternating.

It is indistinct can be measured in both positive and negative cables, they give the same values. This is direct current (DC) used by car batteries and only if the clamp supports that type of current. There are models of the brand that you have that measure the two types of currents, alternating (AC) and continuous (DC) according to the position of the selector key of the clamp. Regards.

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
