The voltage data logger from PCE Instruments is used to record 0 ... 3000 mV signals via up to three input channels. The voltage data logger stores the measured voltages on an SD card in Excel format. In order to record also higher voltage in the range between 0 ... 10 V with the help of the voltage data logger, a voltage divider can be used. The measuring voltages are transmitted via plug-in clamps to the datalogger, which presents the corresponding values directly on the display and at the same time stores them in the memory with the corresponding time stamp. The scaling of the measuring signal is not necessary, since the measured values are stored directly as an mV measured value. In Excel, the scaling can then be carried out quite conveniently manually. The voltage data logger thus determines the pure raw data of the sensors whereby any further processing and data evaluation can be done very flexibly via spreadsheet programs such as Excel.
