Graphical measuring device that combines the advantages of easy readability of an analog display with the accuracy of a digital measuring device. It supports measurement types of analog signal 0/4 to 20 mA as well as DC current measurement at the shunt resistor. Minimum and maximum values are recorded and can be activated and reset via an external switch. The device records measurements over a period of 3 minutes to 72 hours. The time range and the display of the measurement value trend graph can be switched via an external switch. The associated USB configuration software allows the following parameters to be configured: scale range, scale labeling, display design (pointer, tachometer, bar, etc.), start graphic, thresholds for alarm outputs, hysteresis, and more. The software can read the measurement values from the measurement memory and enable continuous data transmission. The measurement values can be graphically evaluated within the software and exported as a CSV file.
