Is a clamp meter better or a multimeter? The difference between a clamp meter and a multimeter
A clamp multimeter can directly measure the current in the circuit without disconnecting the equipment circuit. To measure current with a regular multimeter, it is necessary to string the black and red pointers of the multimeter in the circuit to measure the current.
Clamp on multimeters generally cannot measure small currents.
If it is necessary to measure the analog output of 4-20mA and power supply voltage of the equipment frequently, it is best to use a regular multimeter.
Clamp on multimeters are not very useful to us in daily life and are generally used by professionals in the power industry. A regular multimeter should actually have a spare one for safety reasons, which can be used in any industry or household.
This is a clamp multimeter with AC current mode, resistance mode, diode and buzzer mode, and AC/DC voltage mode.
This is a multimeter, whose measuring function covers the functions of a clamp multimeter.
What is the difference between a clamp multimeter and a regular multimeter?
1. Using a differential clamp multimeter does not require contact with the core of the measuring wire, and a multimeter is not suitable.
2. The function quantity clamp multimeter can be said to be a measuring instrument that stands on the basis of a multimeter and is not as functional as a multimeter.
3. The main measuring object of a clamp multimeter is mainly used for measuring AC current equipment or circuits. The measuring objects of a multimeter almost include all electrical equipment, electronic components, and instruments.
4. The measuring accuracy of the clamp multimeter is not high, and it can only make rough judgments on the operation of equipment or circuits. A better multimeter can achieve accurate measurement, but there is still a gap compared to a pointer multimeter.
5. A clamp multimeter with measurement limitations cannot be used in high-voltage electrical equipment or circuits. A multimeter can measure voltages up to thousands of volts.
In the industrial production process, it is basically a continuous operation. Some low-voltage equipment or circuits in operation need to understand the current situation, and it is impossible to disconnect them and connect them in series with a multimeter to measure the current. This will affect production or cause unnecessary losses. Therefore, in order to measure current without disconnecting the circuit, a clamp multimeter was derived based on the multimeter. Although not as accurate as a multimeter, it can provide effective reference standards for maintenance personnel.
