Observing change in weight (TARE)
The Tare function is very useful if the scale is to be used during a dialysis treatment. Pa-
tient weight can be tared away – the difference in weight then appears as a positive or
negative value in the display.
– Press the green Start key.

and
0.0
appear consec-
utively in the display. The scale is then
automatically set to zero and ready for
operation.
– Get the patient into bed. The patient’s
weight appears in the display.
– In order to tare the patient’s weight
away, activate the Tare function by
pressing the
TARE
key.
The display is reset to zero.
0.0
appears in
the display. The note “NET” appears.
The scale determines the difference in
weight and a positive or negative value ap-
pears in the display.
The Tare function can be turned off again
by pressing the
TARE
key again. The Tare
memory is erased and the current weight
appears in the display.
Note:
If the scale is switched on when the patient is already in bed,
0.0
appears in the
display. A slow continuous change in weight, such as typically occurs during di-
alysis, can be recorded from the
0.0
display only in the above-described Tare
mode. However, the Tare function can be activated only when the display is
not
0.0
.
A small trick overcomes this. Adding another load, e.g. a pillow, changes the dis-
play and the Tare function can be activated.
Tip:
It makes sense to combine this function with the limit value function (see section
entitled "Bottom limit value" on page 31).
