ScaleAC and RMS:
While input type in 5A/60mV : 0...9999A (determined by c.tr.r parameter)
For example: If c.tr.r=5, scale is 0...5A
While input type in CT20/30/60mV :
If ityp=Ct20, input range is 0...300A (determined by turn parameter)
For example: If turn=1, scale is 0...300A
If ityp=Ct30, input range is 0...120A (determined by turn parameter)
For example: If turn=1, scale is 0...120A
DC:
While input type in 5A/60mV : -999...9999A (specified by c.t.r.r parameter)
For example: If c.tr.r=5, scale is -5...5A
While input type in CT20/30/60mV :
DC Measurement can not be performed by using current transformer
If ityp=Shnt, input range is 0..9999A (determined by c.tr.r parameter)
For example: If c.tr.r=5, scale is -5...5A
Sensitivity0.002A x c.t.r.r (for example, 0.01A for c.t.r.r=5)
