Parameter memory
Via the menu of UMG507 „Read out memory manually“ under window „Min-/Max values“ the event memory (Parameter
memory) can be read. The data are saved as a text file. The voltage value behind the dropping time is only slightly
related to the real voltage drop, but is the last voltage value over 10 periods at the time, when it is written into the
parameter memory. This is why the voltage value within the email and within the parameter memory can be different.
The minimum values within the email are measured over 10 periods. More exact data are saved within the trigger
memory (true RMS values over 128 periods) and can be read with Software PSWbasic/professional. While moving
onto the measured curve with the mouse pointer, the effective measured dropping depht is indicated. In the example
below it is 117,5V. The graphical evaluation is possible with PSWprofessional only (option). In software PSWbasic the
data are saved as Text File.
