All RightsReserved.Power ManagementThe devices have a power management system which prevents the titrator from switching off unexpectedlyin the event of a power overload. Tasks which would cause a power overload, because a number of pumps,stirrers and burette drives are already in use, cannot be started at all. A notification brings the start attempt tothe attention of the user. It is advisable, if possible, to connect pumps and stirrers directly to samplechangers or other devices which have their own power supply, such as a TBox, instead of to the titratoritself.9.2 TerminalDimensions Width 194mmDepth 129.5mmHeight 56.7mmWeight 638.4gMaterials Top housing EN ZL-ZnAl4Cu1 (EN Zl-0410)Lower housing Crastin SO653Cover glas Gorilla glas30 Titration Excellence
