PCE Instruments CM 5 Current Clamp Meter AC 0 to 200 AC

Model # CM 5

The digital multimeter is a multimeter with a multitude of different functions. Thus, with the digital multimeter, current measurements up to 200 A AC can be carried out without contact.
Thanks to the contactless current measurements of the digital multimeter can be measured during operation. Thus, no measurement preparation must be made with the digital multimeter, since it is possible to measure directly on the line to be measured.
Another contactless feature of the digital multimeter is the NCV (Not Connected Voltage) measurement. In this measurement, the digital multimeter can indicate whether a voltage is applied to a line.

The digital multimeter is a multimeter with a multitude of different functions. Thus, with the digital multimeter, current measurements up to 200 A AC can be carried out without contact. This current range of the digital multimeter already covers a large range of current measurements. Thanks to the contactless current measurements of the digital multimeter can be measured during operation. Thus, no measurement preparation must be made with the digital multimeter, since it is possible to measure directly on the line to be measured.
Another contactless feature of the digital multimeter is the NCV (Not Connected Voltage) measurement. In this measurement, the digital multimeter can indicate whether a voltage is applied to a line. Again, no measurement preparation must be carried out during operation with the digital multimeter. These two features of the digital multimeter reduce the risk of injury from electric shock.
Other useful functions of the ammeter are the measurement of the resistance and the continuity test. With the continuity check of the digital multimeter, it can be determined, for example, whether a relay in a switch box is completely closed. Thanks to the fast measuring frequency of the digital multimeter, possible power fluctuations can be determined. This makes the digital multimeter an indispensable tool for every electrician.
