WARNING
Risk due to measuring error or measuring inaccuracy
If the mattress tray is not horizontal during weighing or if the weight is falsified by
hoses or cables, measuring errors or inaccuracies may occur.This may result in
incorrect therapy decisions.
► Always position the mattress tray horizontally before weighing.
► Before weighing, make sure that the air bubble in the spirit level is within the
black ring and is not touching the ring.
► Make sure that cables (such as the heated mattress cable) are correctly routed
and do not falsify the weighing result.
► If a weighing result seems implausible, cross check it with a known weight value.
► Double-check therapeutic decisions that are based on the patient's weight by
performing a reference measurement using an external scale.
WARNING

If a taring weight if not determined before weighing, measuring errors may occur.
