Enabling 100ms frequency monitoring on a CM4000
High Speed Monitoring
By default 100ms frequency monitoring is not enabled
100ms Frequency monitoring is disabled by default on the CM4000 series meters. To enable this feature, the following command writes must be executed to the meter:
Write 9020 to register 8000
Write 11 to register 3239
Write 1 to register 8001
Write 9021 to register 8000
This will enable 100ms Frequency monitoring. The value is stored in register 1080 (Units - 0.01 Hz).
