These documents remain the exclusive property of KKA. They may not be transmitted or communicated to a third party without KKA's written consent and shall only be used in connection with this respective contract. (2) The full scope of supply is specified in KKK's written quotation and/or acknowledgement of order respectively. Modifications in the plant design which constitute a technical improvement but do not result in a price increase are permissible. The equipment is supplied in accordance with the applicable Standards and Codes valid in the Federal Republic of Germany at the time the offer is made. II Prices The prices shall be governed by the provision agreed by the contracting parties. III. Payment (1) All payments shall be made without any deduction whatsoever directly to the bank specified by KKA, in accordance with the agreed terms of payment. (2) The equipment shall not pass into the possession of the Purchaser until all payments have been received. In the event that the validity of this title retention is linked to special prerequisites or national regulations in the country of destination, it is the responsibility of the Purchaser to ensure that these conditions are fulfilled. (3) The retention of payments on the grounds of asserted counterclaims made by the Purchaser and offsetting payments in connection with such claims is permitted only insofar that KKA has accepted such claims in writing. For claims made by the Purchaser on the grounds of defective equipment and accepted in writing as such by KKA, payments may only be withheld to an extent considered reasonable by KKA. If the fulfillment of a KKA obligation upon which a payment depends is delayed through no fault of KKA, the payment shall be made on the date originally specified in the Contract. (4) If the Purchaser is in arrears with the contractual payments, KKA may postpone the fulfillment of its own obligations until such payments have been made or may set a time limit for payment. If after expiration of the time limit payment has still not been made, KKA may terminate the Contract. If KKA terminates the Contract, KKA shall be entitled to compensation for all expenditures incurred and for work carried out up to the date of cancellation. If the Purchaser is responsible for the delay in payment, KKA shall be entitled to compensation representing the full contract value, less saved expenditures. IV. Delivery (1) The delivery time is deemed to be kept when the equipment is ready for shipment ex works within the agreed time and, if KKA shall provide for shipment ex works, when the equipment is transferred to the shipping agent. (2) The agreed time of delivery shall only be binding provided that all required documents are made available by the Purchaser in due time, that technical clarification and approval of plans and drawings are obtained in due course, and that the agreed terms of payment and other obligations are fulfilled. if these prerequisites are not fulfilled, the time of delivery shall be extended as is reasonable having regard to all the circumstances of the case.

Different screen displays can be selected as required by the application. The programme for the monitor screen display is stored on EPROM. When the unit is switched on, the programme is immediately loaded and started by means of an autostart command. After interrogation of the parameters preset on the measurement system, both the horizontal and vertical scales for the profile representation are computed and displayed correspondingly. The utilization of the viewing screen is thereby optimized; that is, for a shorter traversal path of the measuring sensor the horizontal scale is spread; the vertical scale is likewise spread for smaller tolerance values. The profile is displayed in the form of a histogramme. The bars are drawn during the scan; hence, the actual value is indicated immediately after computation of the measured values. The position of measurement is indicated by a mark which is displayed in synchronism with the motion of the measuring head. If the measured values exceed the preset tolerance limits, the bars which lie outside the tolerance range are identified by a different colour. Thus, an inadmissible deviation is easily recognizable even from a greater distance. In addition to the histogramme bars, further information is presented graphically and numerically; this information is described by means of the following figures.

These parameters can be stored under a freely selectable product number in the battery-backed data memory and are thus available at any time. The display is conveniently subdivided into two columns. 1. [actual] column The values of the instantaneously valid data record are indicated here. 2. [next] column The next data record is presented here. This data record can be entered or transferred either by means of the keyboard or, as an extension, from a host computer system through an interface RS 232. The entries for the product and order numbers may consist of a maximum of 15 alphanumeric characters; all other entries may comprise a maximum of 15 numeric digits The corresponding line is selected for the entry by pressing the cursor keys, and the line is displayed in blue. Every entry must be terminated by pressing the [Enter] key. ATTENTION! After completion of the entries, the product number must be reentered before storing of the product data record in the memory or transfer from the [next] column to the [actual] column. For reasons of security, this number is deleted during alterations in a data record, in order to avoid possible errors in storing the data record, for example, overwriting of a data record which is still valid.

The record includes all individual rolls manufactured under the specified order number, together with the associated quality data. Individual rolls whose quality data cannot satisfy the desired quality criteria are deleted from this record and documented in a rejection list. Individual rolls are eliminated in the following manner: 1. The corresponding individual roll is selected by means of the cursor keys. (The line is emphasized in colour). 2. After pressing of the [Enter] key, the data on this roll are deleted from the record and transferred to a rejection list. This record is reset and restarted with the [Order change] signal as well as upon alteration of the order number. Moreover, a printer output can be specified by entry in the basic settings before resetting of the record. If the number of individual lines exceeds 200, the record is automatically cleared and then resumed with the subsequent data. With the appropriate entry [Printout order record] in the basic settings, the partial record is printed before resetting.
