Automatic switch-off/economy mode
The scale automatically detects whether it is being operated on batteries or whether it is
connected to the mains.
– Operation on 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 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 depressing and
holding the HOLD/TARE key.
The display is reset to zero. 0.0 appears
in the display. 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.
– 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 scale
switches off automatically (operation on
batteries).
The triangle with the exclamation mark
indicates that this frozen display is an
additional facility which is not subject to
calibration.
