Q: How to auto discharge clamp current meter: The clamp type meter works like a transformer.A primary coil is a traverse through a clamp core, equivalent to the primary coil of a transformer with 1 turns, which is a step-up transformer. The two coil and the ammeter used for measurement constitute the two loop. When the wire is AC current through the coil, which is the alternating magnetic field, induction current is generated in the two loop, the size of the current and a current ratio, the equivalent of a number of turns and two coil inverse. The clamp type ammeter is used for measuring high current. If the current is not large enough, the primary wire can increase the number of turns through the clamp table and divide the measured current by the number of turns.

Q: How to measure the motor current with a multimeter?: If the range is enough, connect in. But don't agree with it, or buy a clamp meter or CT, after the two terminals of your multimeter access on CT. Directly into series, in case it is a big motor, it is dangerous.

Q: How to detect electronic fishing gear?: One is the direct series current measurement table (Figure 1), the input current fishing is motionless on the tens of amperes, reached 100 as Erdogan, the company's LJ-4025NP fishing device to maximum more than 200 amperes. Such a large current, the market generally does not have such a large ammeter, then it is necessary to use resistance sampling method to carry out sampling calculations

Q: How to test the 30KVA capacitor: The capacitance is measured with a capacitor meter, and the charging and discharging test is carried out with a multimeter

Q: The current transformer and the ammeter do not show the same: Is the pointer of the ammeter clear? As you described, the flow ratio at one time should be 160:1, one 87A, and the current number is 0.54A

Q: How to select the clamp meter?: How to use the clip on ammeter instructions, clamp meter using a clamp type table, release date: [2008-12-30] number: [12] classification: browse [FAQ] on ammeter

Q: How can the clamp meter measure current and measure overload current?: Clamp meter working principle: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. Thus, the current meter connected with the two coil is instructed to measure the current of the line to be 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.

Q: A selection table clamp type table: When the jaw is closed in the measurement, if the noise is closed, the jaw can be closed again. If the noise can not be eliminated, the joint surface of the magnetic circuit should be checked whether it is bright and clean and clean when there is dirt.

Q: But after 3 minutes on the machine, there is no electricity, what's the matter?: If you can't open the circuit check all the best hit the table of capacitance, resistance to clamp type table file, two probe and two terminal capacitor contact, began to pass, slowly not normal. The frequent capacitance of the switch is easily damaged by current. If there is no problem, it may be where the leakage of fluoride, or Freon is not enough. If the system does not leak, the difference is only fluoride, that is, fluoride will be OK, if the leak, then a little trouble

Q: How to use the pliers?: When the utility model is used, the movable iron core is opened by pressing the handle, and the conducting wire of the current to be measured is put into the jaw, and the iron core is closed after being released. The current through the wire equivalent transformer primary, secondary inductive current, current meter is connected to the secondary coil, so that the secondary coil current, form scale is good has returned to the current scale, which can indicate the value of measured current. A table is convenient to use, but the accuracy is not high.
