Multi box systems –HF frequency limit is set to 5000 Hz but performance to specification is guaranteed only to 2000 Hz. Above
2000 Hz, full power may not be available due to amplifier unbalance. Current measurements accuracy is affected by system
interface cable cross talk above 2000 Hz.

Frequency measurement specifications valid with output voltage of 30Vrms or higher. If output relay is open,
frequency measurement will return 0.0 Hz.
