If a Meter with 5A input has been ordered for a site but a 1A CT has been installed, can the meter retain accuracy?
Yes, as long as the input to the meter is still within the operating range; this is different for each meter type. Please refer to the Currant Input specifications on the meters Datasheet to determine if the meter will operate properly.
- i.e.: the ION 8600 operating range is accurate for 0.05A to 20A(class 20) and 0.01A to 10A (class 2).
We would not recommend using a secondary step up transformer to bring the input back up to 5A since you would be introducing more inaccuracies(allthough this would give you more resolution but not increase the accuracy).
