Automatic switch-off/economy mode
The scale automatically detects whether it is being operated on rechargeable/non-
chargeable batteries or whether it is connected to the mains.
– Operation on rechargeable/non-chargeable batteries: automatic shut-down after 30
seconds.
– With mains operation: shut-down only via keypad.
Taring weight display (TARE)
The tare function is very useful, for example for determining the weight of a child, animal
or other object placed on the scale in addition to yourself.
Proceed as follows:
– Press the Start key with no load on the
scale.
– First stand on the scales yourself with-
out the additional weight and activate
the Tare function by pressing the 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 take the additional load onto the
scale. You can leave the scale to do so,
in which case ---- appears.
The scale determines the weight of the
additional load.
You can now perform as many weigh-
ing operations as you like.
– Press the key again to deactivate the
Tare function; the scale is then back in
normal weighing mode and the tare val-
ue 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 key whilst the load is on
the scale.
“HOLD” appears in the digital display. The
value is stored until the scale switches off
automatically (operation on batteries).
The triangle with the exclamation mark in-
dicates that this frozen display is an addi-
tional facility which is not subject to
calibration.
