j) CURRENT HARMONICS AND THD METERING
PATH: ACTUAL VALUES  METERING  SOURCE SRC 1  CURRENT HARMONICS
The metered current harmonics values are displayed in this menu. The "SRC 1" text will be replaced by whatever name
was programmed by the user for the associated source (see
SETTINGS  SYSTEM SETUP  SIGNAL SOURCES). Current
harmonics are measured for each source for the total harmonic distortion (THD) and 2nd to 25th harmonics per phase.
6.3.4 SYNCHROCHECK
PATH: ACTUAL VALUES  METERING  SYNCHROCHECK  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 FREQUENCY
PATH: ACTUAL VALUES  METERING  TRACKING FREQUENCY
The tracking frequency is displayed 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.
