Comparison between clamp ammeter and multimeter
Clamp ammeters and multimeters are both necessary "equipment" for electrician technicians. The two instruments are different in the focus of their functions. Clamp ammeters focus on measuring large current lines, while multimeters focus on measuring low voltage and small currents. When repairing circuits, it is sometimes necessary to use both together. For example, when repairing electrical equipment that combines strong currents such as air conditioners, refrigerators, and electrical control equipment, both are sometimes used equally.
The main "specialties" of clamp ammeters
We know the main "specialties" of the clamp ammeter from its common name. We sometimes call it a current measuring clamp. It is an electrical instrument that measures large currents. It can measure AC currents up to 1,000 amps, and can only measure 1 amp at the minimum. No matter how low it is, it cannot be measured accurately. Therefore, its accuracy is only between level 2.5 and level 5. There are many things to pay attention to when measuring large currents, which beginners need to memorize.
The main "specialties" of multimeters
Multimeter is also commonly known as "universal meter". Its main feature is its strong comprehensive ability, which is like "it can afford to put down all kinds of martial arts". It can not only measure AC current, but also AC voltage, DC current and voltage, Resistance, inductance, capacitance, audio level, diode, transistor amplification, transistor type, etc. Moreover, its measurement accuracy is much higher than that of a clamp ammeter, with an accuracy of up to 0.1, especially a digital multimeter. For large currents, current values up to 10A can be measured, which is sufficient for general equipment. Nine times out of ten when I'm servicing or debugging equipment I have to use a multimeter to complete the task. Therefore, in terms of frequency of use, the usage rate of multimeters is much greater than the usage rate of clamp ammeters, so I think multimeters are more useful when repairing electrical equipment.
