    1. ) Only use the included micro­USB adaptor cable. Low quality products can cause false measurements or the destruction of the GoldScreenCard. 2. ) Make sure that the GoldScreencard isn't put on a metallic surface when measuring and calibrating and don't put metallix objects near the GoldScreenCard because this can cause measurement inaccuracies.

  • Page 14: Interpretation Of The Measurement Results

    10. Interpretation of the measurement results The GoldScreenCard uses the electric conductivity of the testing object as a physical measurement size. The testing sample's geometry plays a decisive role because the air gaps between the sensor­ and coin surface caused by the striking contribute significantly to the measurement result.
