FAQ

Can the fluke317 clamp meter test DC current?

But the switch is not allowed to operate when charged. Clamp meter general accuracy is not high, usually 2.5 ~ 5. In order to facilitate the use of the table there are different ranges of switching switches for measuring different levels of current and voltage measurement function. Clamp meter is composed of a current transformer and current meter assembly. The iron core of the current transformer can be opened when the wrench is tightened; the wire through which the current is measured can be cut through the opening of the iron core without cutting off, and when the wrench is released, the iron core is closed. Through the test circuit of the core, the wire becomes the primary coil of the current transformer, in which the current is induced in the two coil through the current. A current meter connected with the two coil is then instructed to measure the current of the line being measured. A table can shift through the switch, the scale change. But the switch is not allowed to operate when charged. Clamp meter general accuracy is not high, usually 2.5 ~ 5. In order to facilitate the use of the table there are different ranges of switching switches for measuring different levels of current and voltage measurement function.

Can the clamp meter measure the direct current?

The new clamp type watches usually have DC current files, and the old-fashioned ones don't.

To measure current, how many transformers are used in 0-100A? How big is the ammeter? How do I get the S1'S2 line?

Under normal circumstances, if one hundred is the maximum power output of current equipment when the transformer is one hundred, 100/5 transformer can; if the rated current of one hundred a, choose 150/5, ammeter and transformer ratio should be one to.Mutual inductor S1 terminal current meter A1, A2, then S2 and then ground

How to accurately measure the Ma level current

I'm afraid the general instrument is not so accurate. You can try to magnify the current and then measure it. Ha-ha！

My model number is UA9250. Would you like to ask how to distinguish the gears on the following table?! There are no letters on it. Some numbers will do. Please explain

Structure and principleClamp meter is essentially composed of a current transformer, a rectifier type clamp wrench and magnetoelectric force instrument.

How to select the clamp meter?

According to your needs test range, select the range of the current, generally the largest 600A, according to your habits, choose digital or pointer type.

Automatic tripping of circuit breaker often, this is why, what to do?

After analyzing the two causes of circuit breaker tripping, some common analysis and treatment methods are summarized. The first is to judge whether it is a circuit problem or a circuit breaker problem. The general process is:Observe whether the burning of a circuit, whether there is odor, the low voltage cabinet within the two control loop whether there is no fault1., when there is a fault point, the switch can be closed, the line problem is explained, and the circuit breaker is irrelevant.2. there is no obvious fault point, in the case of no load, the circuit breaker still can not switch on, it shows that the circuit breaker can not be put into operation, it is the problem of the circuit breaker itself.
