Page 15: Notes On The Use Of Ct Coil
Mesurement Method 9 / 24 4-3. Notes on the Use of CT Coil - Attach the secondary conductor to the position of the CT coil. Adjustments have been made so that correct values can be obtained when measured in this position. -Please fix to secondary conductor so that CT does not move during measurement.
Page 16: Note On The Use Of Tip Voltage Detection Cable
Mesurement Method 10 / 24 4-4. Note on the Use of Tip Voltage Detection Cable Since induced electromotive force by welding current generates induction by the tip voltage detection cable when measuring the tip voltage, as shown in the following figure, please make connection of the tip voltage detection cable.
