Deleting The Measured Values; Using Guest Mode - Hartmann Tensoval duo control Instructions For Use Manual

measured values stored for the res-
pective person. If only two measu-
red values are in memory, the mean
value will be calculated from these
two measured values. If only one
measured value is in memory, no
mean value will be calculated.
You can cancel the memory's recall
of data at any time by pressing the
START/STOP button. Otherwise the
device will switch itself off automa-
tically after approx. 30 seconds.
Even if the power supply fail, e.g.
when changing the batteries, the
stored values will still be available.
5.3 Deleting the measured
values
You can delete all stored data
either in M1 or in M2. To do this,
press the memory button of the
corresponding memories M1 or M2.
The average value will appear on
the display. Hold down the memory
button for a longer time. After four
seconds the display will flash. After
further four seconds all data will be
deleted.
It is not possible to delete individu-
al readings. On the display appears
only M1 or M2.
Important: If you release the
memory button before the end
of the eight second time limit, no
data will be deleted.
If there is a single measured value
in memory, this stored value cannot
be deleted.

5.4 Using guest mode

When a third person uses Tensoval
duo control, it is recommended that
they use the guest mode. This one
is used to store a measured value
neither to the memory positions M1
nor to M2. This avoids bias to the
average values and stored values of
the two main users of the device.
To take measurements in guest
mode, start the measuring proce-
dure by simultaneously pressing
memory buttons M1 and M2. The
START/STOP button need not be
pressed. At the end of measure-
ment the display simultaneously
shows both M1 and M2 above the
measured values rather than either
symbol alone. The measured value
can thus not be applied to either
person, and the measured values
will not be stored.
To switch off the device, press the
START/STOP button, also in guest
