Note: Accuracy specifications are valid above 100 counts. For multi-chassis configurations, Current
and Power range and accuracy specifications are times the number of chassis.
Note: Frequency measurement specification valid for output > 20 Vrms.
Note: Crest Factor accuracy applies for Irms > 50% of max.
Note: Power Factor accuracy applies for PF > 0.5 and VA > 50% of max.
2.1.4 Harmonic Measurements
Harmonic measurement specifications apply to FCS18-3 with –ADV option in three-phase
mode. See notes for single-phase mode or FCS18–1 with –ADV option.

Note: Current range and accuracy specifications are times three in single-phase mode. For multi-
chassis configurations, current accuracy specifications are times the number of chassis. The harmonic
measurement bandwith increases to 48Khz in single-phase mode.
