6.4.3 Tracking frequency
ACTUAL VALUES METERING TRACKING FREQUENCY
The tracking frequency displays here. The frequency is tracked based on the selection of the reference source with the
FREQUENCY AND PHASE REFERENCE setting in the SETTINGS SYSTEM SETUP POWER SYSTEM menu. See the Power
System section of chapter 5 for details.
