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.
