NOTES ON OPERATION
This device fulfils all of the technical requirements that are
compiled in current EC guidelines. The characteristics of this
product qualify it for the CE mark.
This instrument is only to be put into operation under special-
ist supervision in a controlled electromagnetic environment in
research, educational and training facilities (schools, universi-
ties, institutes and laboratories).
The individual connecting leads are each not to be longer
than 2 m.
The instrument can be so influenced by electrostatic charges
and other electromagnetic phenomena (HF, bursts, indirect
lightning discharges) that it no longer works within the given
specifications. Carry out the following measures to reduce or
eliminate the effect of such disturbance: Ensure potential
equalization at the PC (especially with Laptops). Use screen-
ing. When a total failure of the instrument occurs, unplug it
and plug it back in again for a reset.

HANDLING
This section describes the start-up of the sensor and the re-
cording of measurement data. Please read this section thor-

Slide the cuff over the
upper arm until the lower
edge of the cuff is 2-3
cm above the crook of
the arm.
When used on the left
arm, the air hose runs to
the device in the middle
of the crook of the arm.
This automatically marks
the 4 cm long artery is placed
icentrally above the pulse point.
When using the device on the right arm, the cuff must be
turned to the left until the artery marking is positioned on the
pulse point. The air hose then runs along the inside of the
upper arm.
The cuff should be tight enough to allow 2 fingers to fit be-
tween the arm and the cuff. Now pull the free end of the cuff
tight and close the Velcro fastener.
Check that the measuring arrow on the cuff is within the "arm
circumference mark" on the edge of the cuff.
Place the arm with the cuff loosely stretched out on a table
surface and keep it still during the measurement. The palm of
the hand points upwards.
