Weighing scale
The weighing scale is located directly underneath the bed.
During the weighing process, the entire bed and all objects
on it are weighed. By lifting the patient, all other weights are
deducted, so that the baby's weight can be precisely deter-
mined. The accuracy of the weight measurement is not limited
by the objects placed on the bed. These additional objects only
reduce the maximum displayable value of the scale by their
combined weight. In the event of patients that need supply by
hoses, e.g. ventilation hoses, the influence of these hoses on
the measured weight, as with other types of scales, cannot be
fully eliminated. In order to avoid fluctuating weighing results,
the hoses should be removed from the ventilation hose holder,
if fitted, before weighing, and then, after laying the patient on
the bed, the hoses should also be laid on the bed in as strain-
free and horizontal a position as possible. Like items of
clothing, if parts of the hoses are weighed with the patient, they
can lead to a slight increase in measured weight. Since these
deviations are systematic, they do not affect trend observa-
tions.
Weight measurements will only be completely accurate where
taring has been used. Without taring the level of accuracy will
be reduced. Changes made between measurements, such as,
changing in the tilt angle of the device or adding or removing
objects from the bed, may result in inaccurate results.
For weight measurements without using tare, particular atten-
tion must also be paid to ensuring vibration free conditions.
Pressing keys on the control unit too forcibly may lead to vibra-
tion that may reduce the accuracy of the weight measurement.
It is suggested that weighing should only be conducted when
the trolley castors on Caleo are locked. This helps to cushion
vibrations and increases the accuracy of weight measure-
ments.
Before weighing, check that the bed is fully pushed in and is in
the horizontal position.
The spirit levels show whether the bed is horizontal.
1 Spirit levels for the horizontal alignment of Caleo
transverse axis.
2 Spirit level for the horizontal alignment of Caleo
longitudinal axis.
To align the bed horizontally see page 27.
