METERING

6.3.4 Synchrocheck

ACTUAL VALUES  METERING  SYNCHROCHECK  SYNCHROCHECK 1(2)
 SYNCHROCHECK 1

The actual values menu for synchrocheck 2 is identical to that of synchrocheck 1. If a synchrocheck function setting is
"Disabled," the corresponding actual values menu item does not display.

6.3.5 Tracking frequency

ACTUAL VALUES  METERING  TRACKING FREQUENCY
 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
System section of chapter 5 for details.
