Replacing the Calibrator Semi-Rigid/Split Ferrite
Instructions Visual
• Separate the two halves of the ferrite 
(Figure 6-23)
• Position the ferrite such that it’s furthest 
edge is 120 mm (4 ¾”) from the bend of the 
semi-rigid (Figure 6-24)
• Hold the ferrite in place by applying a 
coating of silicone or silicone-rubber 
compound (e. g. RTV) along that 20 mm (¾”) 
section of the semi-rigid
• Join both halves of the ferrite, keeping the 
mating surfaces free of the silicone 
compound if possible
