Cause
How to verify the CM3000/CM4000 series KYZ pulses are being sent.

Resolution

To verify if the KYZ pulses are being sent, you can read the I/O point registers.

For example, the CM4000T Standard output (S01) registers start at 4300.
- If your looking for the IO Point Label read the register Base +1, which is register 4301.
- If your looking for the Discrete Input On/Off Status read the register Base +25, which is register 4325.
- If your looking for the Count read the register Base + 26, which is register 4326.
By referring to the IO Point Label, Discrete Input ON/Off Status and the count, you can verify the KYZ pulse operation.

To find the CM3000 and CM4000 series meter registers, please refer to FA212657.
