A CT multiplier is the ratio of current trough a CT to the output of a CT. Example: A 200/5 Multiplier means that the cable passing through the CT must see 200A to provide a 5A output to the reading meter. The reading meter will then display 200A on it's display but it of course is only seeing 5A itself. Many digital meters have selectable Multipliers so you don't have to stock a wide selection of meters.
