5.2 PRODUCT SETUP CHAPTER 5: SETPOINTS
Maximum Number of Oscillos (Max. Number Osc.):
1 to 20 oscillography records can be selected.
Automatic Overwrite: This setting allows chained oscillographies during the fault (TRIGGER OSCILLO signal
activated). The oscillography module is reset once the data has been completely
stored in Flash memory and the TRIGGER OSCILLO state is deactivated.
Snapshot Events: This setting enables or disables snapshot event generation for the oscillography
element.
Oscillography files calculations
The overall maximum samples capacity is allocated for 27594 samples. The size of each oscillography file depends on the
configured number of oscillographies and is evenly distributed based on the maximum samples value using these
formulas:
Number of samples per oscillography = (27594 samples)/(Max. Number Osc. setpoint)
Number of cycles per oscillography = (Number of samples per oscillography)/(Samples / Cycle setpoint).
EXAMPLE
For a Max. Number Osc. of 4, each record stores 27594 / 4 = 6898 samples per stored oscillo.
If we set the Samples /Cycle setpoint to 64 samples per cycle, each record stores up to 6898 / 64 = 107.78 signal cycles.
This value expressed in terms of time is:
For 50 Hz: 204.79 cycles x 20 ms/cycle = 4095.8 ms.
For 60 Hz: 204.79 cycles x 16.67 ms/cycle = 3413 ms.
5.2.4.2 Oscillography states
After a change in oscillography settings all oscillography files stored on the flash memory are
erased.
