1. To make the calibration you must put at least 10 of Full load into the cabin and then input the same known weight in to LOAD e The third option is COMP 6 and is used for compensating false reading when cabin is empty for 30 To save changed parameters return to weight screen If you don t leave menu device will after 60s automatically return to weight screen and after 120s display will go off Buttons e P button is used for confirming input e E button is used for escape e UP button is used for moving up in menu or increasing values e DOWN button is used for moving down in menu or decreasing values ODOC UP DOWN Figure 3 MT11 display buttons 6 Programming 1 Start the programming procedure with setting the rino nc Full load because with this parameter you set the maximum weight for the cabin without it you can t make the calibration 2 Set the empty lift in to the middle of the shaft and make zero point with TARE 4 parameter 3 Load cabin with a known weight and input that weight in to parameter LOAD 5 Pres button P to start the calibration 4 When the calibration was successful you will be prompted to parameter CALIBRATION If you want to use calibration the weight device will compensate every weight if different of 0 if the lift was Stationary for 30min 5 We recommend that COMP is set to 1 SEC Electronics MT11 MT11_V2 1 page 5 GB Menu flowchart To view present weigh2.
