connection to the analogue load cell port of an Elevation. Due to limitations within the
Elevation this is not the recommended way of Linking a LibraCELL to an Elevation. It is
recommend that a LibraPRO is used whenever possible. The analogue input of the
Elevation is low resolution input and accepts an input voltage between 0 and 5V. The
analogue port of a LibraCELL is shown below
If required a specific cable can be purchased from Kinesys for connecting the analogue
port of a LIbraCELL to an Elevation. The part number of this cable is CBL-80-000
When a LibraCELL is connected to the Analogue load cell port of an Elevation a specific
scaling factor should be used in Vector or K2 as shown below.
For 3.25T cells use a scaling factor of 3611
For 4.75T cells use a scaling factor of 5278

Adjusting The Zero Offset
All LibraCELLs are calibrated when they leave the factory, during the lifetime of the cell the
zero point of the LibraCELL can drift slightly resulting in reduced accuracy. This is often
seen as the LibraCELL registering a weight when load applied.
If this occurs, the end-user has the option to correct a maximum drift of 50kg. If the value
to correct is larger than 50kg, contact your supplier.
In order of recalibrate the zero value, the end-user should power up the cell whilst
pressing the middle button. LibraCELL will display "CAL " instead of the version number to
indicate the recalibration action. When the LibraCELL finishes the booting process, the
display must show a load value of 0Kg to confirm the recalibration process.
Note that this is not the LibraCELL Tare functionality, to apply a Tare see 'Editing a
Parameter via the Keypad' section.
