PCE Instruments Clamp meter

The ammeter is the ideal measuring instrument for measuring voltages up to 1500 V AC/DC and currents of up to 1000 A AC/DC. The current measurement at the ammeter is conducted inductively. For this purpose, the supply cable is placed in the current clamp by the ammeter. This has the special advantage that the current can be measured during operation. This means that the ammeter can be used, for example, for maintenance work on a photovoltaic system. Photovoltaic systems consist of many different solar cells, which are connected in series with each other. Here, the individual currents of individual series can be measured with the ammeter in order to limit possible errors. In addition to the normal voltage and current measurement, the ammeter can also measure the inrush current. Inrush currents are currents that are particularly high at the moment of switch-on. These currents occur when starting motors for ventilation systems, for example, or when switching on a stadium lighting. This measurement with the am...
