The option package includes the use of the additional functions “option remote control“ and „option air volume measurement“ in the smart memo. The period of use is one year. The annual fee is due on date of order in terms of prepaid charges. After expiration of the period of use the option package will be inactivated. A new or subsequent order of the option package can be placed at any time. The annual fee can be payed for multiple years in advance. This option package can only be used in conjunction with the MPP 30-30 and the smart memo. Another requirement is the option „flow measurement“ in the MPP 30-30. The following services are included: Option remote control This option means that the smart memo and the MPP 30-30 can communicate with each other and exchange measured values. Test sequences for water pressure tests can be carried out partially automated. The smart memo controls the pump and starts/stops the pressure control/ maintenance at the right time. Option air volume measurement With the help of this option a determination of the residual air in the tested pipe is performed. Directly after the end of the pressure build-up phase, a rating for the freedom of air in the pipe is displayed. With the air volume measurement, the smart memo can detect critical high air contents at an early stage and the user is spared unnecessary time and effort. For the time being, this function is only available for the contraction method (W 400-2/W 101/EN805). This option can currently only be configured after the LTE-GPS Option (222610) has been selected.
