Graphical measuring device that combines the advantage of easy readability of an analog display with the accuracy of a digital measuring device. The multi-display with RGB lighting can show up to 4 parameters simultaneously and assign individual color warnings for threshold values. It supports a wide range of measurement types (AC/DC voltage, AC/DC current via external shunt resistor, frequency, power, cosine phi). The device can switch between the individual measurement functions during operation using a relay contact. Minimum and maximum values for up to 4 parameters are recorded and can be activated and reset via a jumper or external switch. The device records measurement values of one parameter over a duration of three minutes to 14 days. The time range and the display of the trend graph of the measurement values can be switched using an external switch. The accompanying USB configuration software allows the following parameters to be configured: scale range, scale labeling, display design (pointer, dial, bar, etc.), start graphic, lighting color, threshold values for alarm outputs, color warning per threshold (steady or blinking), hysteresis, and much more. The software can read the measurement values from the memory and enable continuous measurement value transmission for up to 4 parameters. The measurement values can be graphically analyzed within the software and exported as a CSV file.
