What is the capacity meter?
Capacitance meter is a specialized piece of test device. It is used to determine the potential capacity of the capacitor. These meters come in many varieties and sizes to measure capacity in many different contexts. The ability to measure capacity is included in some but not all multimeters.
Physically, most of these devices are simple pocket units with two wires that can be connected to the test capacitor. Older models used an analog display, but they are now quite unusual. Specialized types of capacitance meter, especially those for testing very large or very small capacitors, will probably be larger units with different types of specialized probes suitable for the type of measurement, which is designed for a certain capacity meter. Electric charge
can be temporarily accumulated and stored in a capacitor. Capacitors hold energy in the form of positive and negative rounds on two conductor plates that are separated by. The fields are formed between these elements and may contain a fee. This fee can be released later. The capacitors are not as useful for long -term energy storage as batteries, but are able to release the stored energy much faster, which makes them useful for certain applications that require such rapid release, but also potentially dangerous.
The capacitor's ability to accumulate electric charge is called its capacity and this value is measured by the capacity meter. The simplest measurement method is to apply the electric current to the drained capacitor and then measure the speed at which the capacitor voltage changes. With the known input, this process can be used to determine the capacity of relatively large capacitors with a small test current. Alternating current at a stable voltage can also be used for test purposes.
capacitors are produced in a wide range of size.Large models used in power transmission can contain many orders of greater electricity than extremely small capacitors built into modern integrated circuits. The capacitor size range means that most types of capacity meter is optimized to measure capacity capacitors only by certain sizes.
Small test current generated by the function of the standard pocket digital multimeter capacity is not enough to create accurate reading for a large industrial capacitor. Similarly, the same small current can actually be strong enough to overcome the resistor in a small capacitor located on the circuit board. There are specialized and high -precision capacitance meter models to measure capacitance at this level.
