What is a digital clamp meter?

Digital terminal meter is a device that measures current in amps (a) by magnetic induction. This type of measurement is non -intensive and very comfortable. The digital clamp meter is open and the cable whose current needs is closed in the clamp loop. After the current subtraction is performed, the clamp meter is removed, and all of this can be done without interrupting the continuity of the test cable. In old methods, an ammeter must be inserted, which meant a current disturbance for measurement. A piece of wire with an electric current flowing through it will also have a magnetic field with intensity in relation to the current flow. This magnetic field can induce a current flow in the second wire. If the second wire is correctly created, a second current can be created in ratio to the current on the first cable. The clamp connects the magnetic field from the wire to the second conductor.

Magnetic core metal metal is used to produce a digital clamp meter andIt provides good and linear reading on the second cable that can be visualized as a "pick -up" coil. The clamping is a closed magnetic circuit where the magnetic flow intensity in the core is in proportion to the sampled current. The terminal meter can be considered a transformer where the primary winding is a test cable and the secondary winding is the measurement or winding of the sampling.

AC current is directly measurable using a digital type of induction type. With the correct conversion of analogue to digital and good design, the terminal meter can become a digital terminal meter. The analogue circuits to the digital converter together with the numerical display form a key digital part of the meter.

If direct current (DC) needs to be measured, induction-Type clamp may not work. Induction type meters rely on alternative current characteristics to induce a current from measured to sampling windings. For direct current, devices such as Effects Effect converters are used to measure static orunchanged magnetic fields.

The

digital clamp meter is very useful for quick load control and temporary load through the maximum detention function. For example, in the maintenance of high -performance engines, initial currents may increase to an average level, such as 35 A. If the necessary maintenance may be required.
