Is a clamp-on ammeter a multimeter replacement?
Clamp-on ammeter main "speciality"
Clamp ammeter we know from its common name to see its main "speciality", we sometimes call it a current measuring clamp. It is the measurement of large currents of a kind of electrical instrumentation, its measuring current up to 1000 amperes of AC current, the minimum can only measure the flow of 1 ampere, and then low can not be measured accurately. So its accuracy is only 2.5 to 5 levels of accuracy, in the measurement of large currents, it should pay attention to more matters for beginners need to be familiar with.
The main "speciality" of the multimeter
Multimeter we also commonly known as the "multimeter", its main strength is the ability to integrate, as if "eighteen arts and crafts all can afford to put down", not only can measure AC current can also measure AC voltage, DC current and voltage, resistance, inductance, capacitance, Audio level, diode, transistor amplification, transistor type, etc., and its measurement accuracy than the clamp-on ammeter is much higher than its accuracy of up to 0.1, especially the digital multimeter. For large currents can be measured up to 10A current value, for general equipment is enough. I repair and debugging equipment in the ten times I have to have nine times to use the multimeter to complete the task. So from the frequency of use of the multimeter is far greater than the use of the clamp-on ammeter, so I think the multimeter in the maintenance of electrical equipment is good to use.
Multimeter with clamp-on ammeter
With the promotion of digital and new product research and development now more and more instruments are used in the digital and has become a trend of development, analogue instrumentation slowly withdrawn from the use of the "stage". Now the clamp-on ammeter also appeared digital, its function is no longer a single measurement instrument. Digital clamp-on ammeter measurement accuracy in the improvement of its measurement of physical quantities are also "rich" up, such as the measurement of current, voltage, resistance, active power, frequency, phase angle, power factor and other physical quantities. With a multimeter and clamp ammeter dual function. I think this instrument will be favoured by the majority of electrical technicians in the future.
