To set values to zero, right click on the group in the navigation to open a context menu.
Click on 5HVHW.
Note :
By selecting the 5HVHW command, all values are reset to zero without further inquiry.
This procedure cannot be undone.
Waveform data is stored in the device and can be graphically represented on a PC
®
using DIGSI 4, together with the program DIGRA
waveform capturing — such as duration and pre- and post-trigger times — are set ac-
cording to Chapter 6.
To view the waveform data on a PC, one of the programs DIGRA
Viewer (included with SIMATIC Manager) is needed. Do the following:
Double click on 2VFLOORJUDSKLF )DXOW 5HFRUGV (Figure 7-29). The folders listed
in the right window show an overview of oscillographic records. The records are iden-
tified with a network fault number, a fault record number, and the date and time.
By double clicking on an fault record in the list view in the right side of the window, one
of the above programs is opened, and the selected waveform data are loaded. (See
®
also DIGSI 4, Operating Handbook, order no. E50417–H1176–C097, Sub-section
8.3.3.).

DIGRA 4 provides support in the analysis of faults on the power system. The pro-
gram graphically prepares the data recorded during a fault, and calculates additional
measurement quantities, such as impedances or rms values.
