The main "features" of the clamp ammeter
We know the main "features" of the clamp ammeter from its common name, and we sometimes call it a current measuring clamp. It is an electrical instrument for measuring large currents. It can measure alternating currents of up to 1000 amperes. The minimum current can only be measured by 1 ampere. No matter how low it is, it cannot be measured accurately. Therefore, its accuracy is only grade 2.5 to grade 5. There are many things to pay attention to when measuring large currents, which needs to be memorized for beginners.
The main "features" of the multimeter
The multimeter is also commonly known as "universal meter". Its main feature is strong comprehensive ability, such as "eighteen martial arts can be afforded and put down". It can not only measure AC current, but also measure AC voltage, DC current and voltage, Resistance, inductance, capacitance, audio level, diode, transistor magnification, transistor type, etc., and its measurement accuracy is much higher than that of a clamp ammeter, and its accuracy can reach 0.1, especially a digital multimeter. For large currents, it can measure current values up to 10A, which is sufficient for general equipment. Nine times out of ten when I repair and debug equipment, I use a multimeter to get the job done. Therefore, in terms of frequency of use, the usage rate of multimeters is much larger than that of clamp-on ammeters, so I think multimeters are easy to use when repairing electrical equipment.
Multimeter with Clamp Ammeter
With the promotion of digitization and the research and development of new products, more and more instruments have adopted digitization and become a development trend, and analog instruments have gradually withdrawn from the "stage". Now the clamp-type ammeter has also appeared digital, and its function is no longer a single measuring instrument. While the measurement accuracy of digital clamp ammeter is improved, the physical quantities it measures are also "enriched", such as current, voltage, resistance, active power, frequency, phase angle, power factor and other physical quantities. Has the dual function of a multimeter and a clamp-on ammeter. I think such instruments will be favored by the majority of electrical technicians in the future.
