Inrush current measurement / VFD function / Incl. ISO calibration certificate

The clamp meter is the ideal measuring device for measuring voltages up to 1500 V AC/DC and currents up to 1000 A AC/DC. The current measurement with the clamp meter is inductive. To do this, the supply line is placed in the clamp meter. This has the particular advantage that the current can be measured during operation. This means that the clamp meter is used, for example, for maintenance work on a photovoltaic system. Photovoltaic systems consist of many different solar cells that are connected in series with one another. Here, the current clamps can be used to measure the individual currents of individual rows in order to limit possible errors.

In addition to normal voltage and current measurements, the clamp meter can also measure the inrush current. Inrush currents are currents that are particularly high when the device is switched on. These currents arise when motors start up for ventilation systems, for example, or when stadium lighting is switched on. This measurement with the clamp meter is particularly important for dimensioning the supply line and fuses. Frequency converters are converters that output the voltage on the primary side with a changed frequency and amplitude on the secondary side. With the clamp meter and the VFD measurement function, measurements can be carried out up to a frequency of 45 Hz ... 1 kHz.

The clamp meter also has a Bluetooth 4.0 interface. With this interface on the clamp meter, a connection to an Android and iOS device can be established. With the free “Meterbox Pro” app, the values ​​measured by the clamp meter can be displayed and saved for later analysis.

With the data logging function, the clamp meter can save all measured values ​​at any set interval. After a measurement, the values ​​can be graphically displayed using the clamp meter. Each individual measuring point can also be read individually from the clamp meter. The storage capacity of the clamp meter has a size of 16 groups and a total storage capacity of 100,000 measured values. With the clamp meter, the measured value is saved with the date and time.

The clamp meter can be expanded with an optional current clamp. The additional current clamp to the clamp meter is flexible and can therefore be adapted to the measuring task. With the extended clamp-on ammeter, current measurements of up to 3000 A AC can be carried out. The flexible current clamp is connected to the voltage input of the clamp meter. The current clamp converts the voltage value into a usable current value and shows it on the display.

Because of its many different functions and the high measuring range, the clamp meter is used, for example, for checking photovoltaic systems, hydroelectric power plants, wind power plants or for installing immovable electrical machines. The clamp meter is equipped with an ISO calibration certificate.
