Is a multimeter better with pliers or without?
This focuses on the focus of work, such as the ease of using a specialized clamp current meter for electrical maintenance of power lines, and the ease of using a multimeter for electrical maintenance or weak current personnel.
The dedicated clamp current meter detects the current of the circuit with high accuracy, although its function is single, it is sufficient to meet the current detection of the circuit. Simply put, a clamp current meter is composed of a current transformer and an ammeter. During the measurement process, it is necessary to switch gears and must detach from the measured wire in order to switch gears. Because shifting gears can cause an instantaneous open circuit on the secondary side of the current transformer, if the measured current is high, an instantaneous high voltage will be generated on the secondary side of the current transformer, and the clamp current meter is likely to burn out.
The clamp current meter was originally used to detect AC current and measure the current level of the running circuit. From this, it can be seen that current detection can be carried out under constant electricity, and it is specifically designed to detect high AC currents. Nowadays, the functions of clamp flow meters are no longer singular, and the functions of multimeter clamp flow meters also have.
Therefore, each has its own advantages. If you want to detect the current in a running circuit, the clamp current meter is definitely useful. Do not disconnect the circuit and directly perform current detection. Using a multimeter requires disconnecting the circuit in order to perform measurements. If the equipment cannot be powered off arbitrarily during continuous production, the multimeter will be unusable.
The current clamp watch is no longer the clamp watch of decades ago. It adopts the Hall induction principle and can not only measure AC circuits and DC currents; Insert the probe and transform it into a digital multimeter, which can also measure parameters such as voltage, resistance, capacitance, frequency, etc. As for accuracy, it is no different from a digital multimeter.
Their differences
If it is to be said which one is better to use than a multimeter, there are still some differences in their experience during use.
1. A clamp meter can continuously measure current, which a multimeter cannot do. If it is necessary to frequently measure AC and DC currents, it is recommended to buy a clamp meter; You don't need to measure the current frequently to buy a multimeter.
In order to continuously measure current, the clamp meter must have a clamp, so its body shape is relatively slender. Because there is no bracket on the back of the clamp watch, I personally feel that the clamp watch is more inclined to be held in hand for measurement; The multimeter has a bracket on the back, which is more inclined to be placed on a table for measurement. So if you often sit at a table for maintenance, it's better to buy a multimeter for convenience, otherwise it's uncomfortable to stretch your neck and look at the screen of the clamp watch.
In terms of price, the clamp meter not only has most of the functions of a multimeter, but also includes a current transformer, so the price is relatively more expensive.
