Connecting the connecting cable to the weighing platform
The connecting cable of the display part is used to transmit digital data which are consid-
erably less sensitive to interference than the otherwise conventional small analog meas-
uring signals. Ageing and wear on the cable and on the plug contacts thus have no effect
on the accuracy of the scale.
To make the connection, proceed as outlined below:
– Connect the cable of the display case to
the socket under the carrying handle.
– Then place the scale upright again.
The cable may not contact the weighing
platform during weighing, as this might
falsify the result.
