The Voltmeter is a useful tool to examine solar cells for their characteristics. With a DC voltage range of 0 … 60 V and a DC current range of 0 … 12 A, the Voltmeter covers a large number of solar modules. The determined characteristic curves are saved directly on the solar module tester. Up to 100 measurements can be stored in the data memory of the Voltmeter. The stored measured values can then be read out and further processed on a PC with the associated software. In addition, it is possible to operate the Voltmeter completely via the software.
The Voltmeter has two different measuring functions for determining the characteristics of a solar module. In automatic mode, the characteristic curve is created with automatic parameters by the Voltmeter. This gives the operator a first impression of the state of the solar module. In manual mode, the start and end of the current value can be set on the Voltmeter. If the area of the solar module and the power of the incoming radiation are stored in W/m², the Voltmeter can calculate the efficiency and the fill factor of the cell. Another measuring function with the solar module tester is the one-point measurement. A specific current can be controlled and checked by the Voltmeter.
The LCD display of the Voltmeter has a size of 4.8“. This means that the characteristic curve and all measured values can be read off at the same time. In order to analyze the characteristic curve better, each individual measuring point on the Voltmeter can be approached. For a different view of the X and Y axes, you can switch between current, voltage and power by pressing a button on the Voltmeter.
Because of its many different functions, the Voltmeter is the ideal measuring device to examine solar modules for their effectiveness. The Voltmeter is therefore used in photovoltaic systems and research facilities for the further development of solar modules. The Voltmeter can optionally be equipped with an ISO calibration certificate.
