The syst em p cks up 13 channels of v brat on s gnals of the dev ce, and d s plays such analys s results of v brat on as mechan cal mages, ampl tudes , spectrum, autocorrelat on and so on . When the v brat on ampl tude of any channel exceeds a def ned value, the system w ll automat cally alarm and restore all v brat on data last ng 5 to 15 m nutes before the event happens for deta led analys s . T he ma n l ne electr cal s gnals of 6 channels for the synchronous motor are also mon tored .
