Contact fingers for a testing apparatus for surface insulation resistivity |
摘要 |
An improved Franklin tester for measuring surface insulation resistivity on magnetic sheets. The contact fingers of the prior art tester are modified to accommodate an articulated contact tip. The articulated tip pivots when the tester is clamped on a magnetic sheet to thereby maximize the area of contact. Preferably the articulated tips are formed of stainless steel to overcome the rapid deterioration of the prior brass contact fingers.
