1. DESCRIPTION OF DEVICE
1.1 Intended use
The medical scale is mainly used at hospitals, practices and inpatient care
facilities in accordance with national regulations.
The scale seca 955 is for conventional determination of weight and establish-
ment of general state of nutrition; it assists the physician supervising treat-
ment in making a diagnosis or deciding on a course of treatment.
To make an accurate diagnosis, however, other specific examinations have to
be ordered by the physician and their results taken into account, in addition to
determining a weight value.
1.2 Description of function
The scale is used to determine weight.
Some versions of these scales allow you to switch the weight display
between kilos (kg), pounds (lbs) and stones (sts).
The height value can be entered manually to calculate the body mass index.
The seca 955 is not intended for the transport of people or objects.
1.3 User qualification
The device may only be operated by healthcare professionals.

ues are automatically cleared after 5 minutes.

deduct it from the measuring result when a patient is weighed fully dressed.
1. Select the item “Pt” in the menu.
The message “Pt” appears.
2. Confirm your selection.
Arrows can be seen flashing in the display.
The additional weight last stored is displayed.
3. You can accept the stored value or adjust it using the arrow keys.
NOTE
If you enter the value “0”, the function will be switched off. The
message “Pt” will no longer be displayed.
4. Confirm your selection.
5. Ask the patient to sit down on the scale.
The patient's weight is displayed.
The additional weight stored has been automatically deducted.

7. Confirm your selection.
The function is disabled.
You will leave the menu automatically.
NOTE

sage “Pt” is no longer displayed when you switch the scale on again.
