If defects occur during the warranty period and are reported in time, they will be repaired – at the discretion of ZIMMERLI MESSTECHNIK – or the defective part will be replaced. If ZIMMERLI MESSTECHNIK replaces defective parts, the latter become its property. The original warranty period shall not be extended by the rectification of defects or replacement delivery. Further claims of the customer, in particular claims for damages, cancellation, reduction or retention of the invoice amount are excluded. In particular, ZIMMERLI MESSTECHNIK is not liable for indirect or consequential damages, such as lost profits, claims to third parties, unrealised savings, additional expenses of the customer or damages to the devices. The warranty is excluded for damages that occur after the transfer of risk as a result of operational disturbances of the customer, improper handling or operation, improper or unauthorised interventions, excessive stress, unsuitable operating materials or other reasons for which ZIMMERLI MESSTECHNIK is not responsible. If the customer or a third party has made changes or repairs to the delivery items, any claim to warranty shall expire.
