Page 8: Key Functions And Programming
Universal Measuring Device UMG 500A Key functions and Programming Programming of Universal Measuring Device UMG 500A is carried out with the remote/local contact open, using the keyboard and the digital display. Following a power failure, it is not necessary to reprogram the device, because the programmed data and peak values are stored. -
Page 9: Voltage
Universal Measuring Device UMG 500A Voltage When this key is pressed, the device displays the effective value of the voltage to neutral or to the next phase (L1-L2; L2-L3; L3-L1). The unit is indicated by the LED “V”. Instruments with the option “kV” display the measurement value in the format ##.## kV. -
Page 10: Reactive Power
Universal Measuring Device UMG 500A Reactive power This function displays the reactive power in the outer conductors or the sum of their reactive powers. The unit “kvar” is indicated by an LED. The direction of the phase displacement between voltage and current is indicated by the LEDs “ind”... -
Page 11: Analogue Output
Universal Measuring Device UMG 500A Analogue output Allocation 0..20 mA In order to allocate a particular measuring function to the output, the desired measuring function .. / 5A and the measurement phase must first be selected. After this, the function set is allocated to the analogue output by operating the keys illustrated on the left. -
Page 12: Peak Values
Universal Measuring Device UMG 500A Peak values Universal measuring device UMG 500A stores the peak value and the date and time of registering for most of the measuring functions. There is no storage of peak values for real work and reactive work. In the case of harmonic waves, the peak values are stored without date and time. -
