Taring weight display (TARE)
The Tare function is very useful if an additional weight, e.g. that of a wheelchair, is to be
ignored for weighing purposes.
Proceed as follows:
– Press the START key with no load on
the scale.
– First place the additional weight (e.g.
the wheelchair) on the scale and acti-
vate the Tare function by pressing and
holding the HOLD/TARE key.
The display is reset to zero, 0.0 flashes
in the display until weight is detected to
be stable. Only then is the Tare function
fully activated. The note “NET” appears.
– Now move the patient and the wheel-
chair previously weighed onto the scale.
The scale determines the patient’s
weight.
You can now perform as many weigh-
ing operations as you like.
– 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.
Store weight value (HOLD)
You can also continue displaying the weight determined once the load has been removed.
This makes it possible to look after a patient first, before having to note the weight:
– Press the HOLD/TARE key whilst the
load is on the scale.
“HOLD” appears in the digital display.
The value is stored until the HOLD func-
tion switches off automatically.
– The HOLD function can be switched off
by pressing the HOLD/TARE key
again.
– 0.0 appears in the display if the scale
has no load on it, otherwise the current
weight. The “HOLD“ display vanishes.
Note:
The HOLD function can also be used if the TARE function has been executed
beforehand.
