Common use of Adjustment and calibration Clause in Contracts

Adjustment and calibration. To perform the headform test the phantom head is fixed to the cross arm of the guide system (Figure 2.2) and moved to the required drop height by means of a lifting device. During the headform test the cross arm with the phantom head is released. After passing the height adjustable light barrier the phantom head is released from the cross arm, the cross arm's fall is dampened and the phantom head falls onto the sample. No impulse may be given to the phantom head by the drop appliance or by the measuring cable, so that it is accelerated only by gravity and falls vertically.
