The display may be usefulto calibrate the feature by compensating the angular errors of the CTs and VTs with the use of the RCA and CALIBRATIONsettings.6.3.4 SYNCHROCHECKPATH: ACTUAL VALUES ÖØ METERING ÖØ SYNCHROCHECK Ö SYNCHROCHECK 1(2)The actual values menu for synchrocheck 2 is identical to that of synchrocheck 1. If a synchrocheck function setting is "Dis-abled", the corresponding actual values menu item will not be displayed.6.3.5 TRACKING FREQUENCYPATH: ACTUAL VALUES ÖØ METERING ÖØ TRACKING FREQUENCYThe tracking frequency is displayed here. The frequency is tracked based on the selection of the reference source with theFREQUENCY AND PHASE REFERENCE setting in the SETTINGS ÖØ SYSTEM SETUP ÖØ POWER SYSTEM menu.
