ION 8650 Modbus and DNP values do not scale correctly

Issue
Scaling of DNP and Modbus output values may be incorrect when the PT ratio is set at 1:1. This will turn on the Scaled Operational Values output prematurely. It should only be enabled when BOTH the PT AND CT ratios are set to 1:1.

Cause
An incorrect formula is populated within the Arithmetic 74 (SetRatios1) formula 1 for the A and B variants (C variant is correct).
The incorrect formula on Variant A and B is IF(S1=S2,1,0), which can be seen below.

Resolution
The corrected formula can be seen below as IF(AND(S1=S2,S3=S4),1,0)


The fix to this formula can be done directly in unlocked meters using IONSetup or Designer, or download the corrected template listed below.
