File Size: 63 KB
Last Update: 8/3/2011

Description:

An analog calibration issue exists for OptoEMU-SNR-3V units with date codes of July 2011 and earlier. This issue only affects customers who are using the product with a "direct connection," that is, measuring power via current transformers (CTs). The calibration issue does not affect those using the product with pulse inputs.

This technical note shows you how to determine whether your unit is affected and how to fix the issue. Use this technical note with the OptoEMU Sensor Analog Calibration File, which contains a command line utility.
