Memory function (TARE)
The new kind of memory function on this scale means that the Tare function can also be
used to determine patient weight if the additional weight (such as a stretcher or wheel-
chair) cannot be weighed separately beforehand. If a patient is brought into A&E, for ex-
ample, he is placed on the scale still on the stretcher and the memory function is
activated. Once the patient has been looked after, the empty stretcher (together with all
the other items which were used for emergency medical treatment) is put back on the
scale to determine patient weight.
Proceed as follows:
– Press the Start key with no load on the
scale.
– Put the patient on the scale with the
stretcher or the wheelchair and activate
the Tare function by pressing and hold-
ing HOLD/TARE.
The display is reset to zero,
in the display until weight is detected to
be stable. Only then is the Tare function
fully activated. The note "NET" appears.
– Now take the patient off the scale and
look after him.
The display now shows total weight (pa-
tient plus additional load) as a negative
value. This value is stored until the Tare
function is switched off.
– Once you have looked after the patient,
put the empty stretcher back on the
scale (together with any equipment or
blankets which were used for emergen-
cy medical treatment). The additional
weight is now deducted from the stored
total weight, giving you the patient's
weight (likewise displayed as a negative
value).
– Hold the key down again to deactivate
the Tare function; the scale is then back
in normal weighing mode and the tare
value has been erased.
– The tare value is likewise erased by the
scale being switched off.
Note:
You can of course also use the Tare function in the usual manner to tare an additional
weight (e.g. a wheelchair) beforehand, so as to obtain patient weight directly when weigh-
ing the patient together with the additional weight.
