GOLDANALYTIX GOLDSCREENPEN Bedienungsanleitung Seite 26

Conditions for optimal results (see Figure 2):
 The device is also able to determine the conductance through thin blisters and films
(maximum thickness ca. 0.25 mm). Hereby, the accuracy will decrease. Nevertheless, best
results will be achieved with direct contact of the tip to the metal.
 The contact surface should at least cover the sensor tip (ca. 3.5 mm) in order to
guarantee an accurate measurement.
 The contact surface should be as plane as possible (we recommend an area with little or
even without mintage) and not strongly curved.
 Please hold the tip perpendicular to the testing sample, not diagonally.
 The thickness of the sample has to be bigger than the penetration depth, i.e. at least
0.5 mm.
