4 Decimal Resolution for Frequency Readings @ PM180 and PRO Series

We have detected a new requirement for compact, cost effective power meters, capable of hi-res frequency metering (frequency @  3 or 4 decimals: 0.0001 Hz), including data transmission every cycle. This is of essence for ancillary services in the national electricity markets.

The SATEC PRO Series complies with this, providing frequency readings every cycle with 0.01HZ accuracy at ocv and with 0.0003HZ error at osv.
