What do I do if calculated analog point values are incorrect?

If the calculated analog point values are incorrect, and all of the physical inputs are reporting correctly, there can be one of three problems.

  • If using a PROM where DAQ has done the configuration in the EPROM, the configuration may be incorrect.

  • If using a configuration done in CallistoView, it may be incorrect. Verify the types of metering used and that the right points have been selected for reporting. Also, check that the mapping is in the expected order.

  • There is a phasing problem on the inputs from the field. Verify that the voltage and current pairs are presented to the terminal blocks in the correct order, and that Phase A Current is paired with Phase A Voltage, Phase B with Phase B, etc. for all pairs.

It is extremely unlikely that there is a hardware problem if the physical inputs are all reporting correctly.
