To perform a single-point calibration on a current transducer:
1. GotoSystems > Inventory > Current Transducers andselectoneoftheavailablecurrent
transducersbyselectingtheGO TO button.
2. SettheOffset tozero.
3. Measuretheactualcurrentflowinginamps.Itmaybeeasiesttodothismeasurementat0.0amps.
4. Recordthemeasuredvalue:____________A.
5. Subtractthedisplayedvalue:____________A,fromthewebinterface.
6. Calculatethenewoffset:_____________A.Offset=MeasuredValue-DisplayedValue
7. SelecttheEDIT buttonoftheOffset field.EnterthenewoffsetinampsandselectSave.
8. VerifythattheOffset fieldwasupdated,andthatthenewdisplayedvaluematchesthemeasured
