4. Putting the blood-pressure monitor into operation
4.1. Inserting the batteries
After you have unpacked your device, first insert the batteries.
The battery compartment is located on the underside of the
device (see illustration).
a) Remove cover as illustrated
b) Insert the batteries (4 x size AA 1,5 V), thereby
observing the indicated polarity.
c) If the battery warning appears in the display, the
batteries are empty and must be replaced by new ones.
Attention!
• After the battery warning appears, the device is
blocked until the batteries have been replaced.
• Please use «AA» Long-Life or Alkaline 1.5 V Batteries.
The use of 1.2 V Accumulators is not recommended.
• If the blood-pressure monitor is left unused for long
periods, please remove the batteries from the device.
Functional check: Hold on the O/I button down to test all the
display elements. When functioning correctly all segments
must appear.
4.2. Tube connection
Cuff AC-1 (1-tube cuff + T-connector):
Set up (or check) the tube connections between cuff,
instrument and pump ball as shown in the diagram.
5. Carrying out a measurement
5.1. Before the measurement
• Avoid eating, smoking as well as all forms of exertion directly before the measurement. All these
factors influence the measurement result. Try and find time to relax by sitting in an armchair in a quite
atmosphere for about 5 minutes before the measurement.
• Remove any garment that fits closely to your upper arm.
• Measure always on the same arm (normally left).
• Attempt to carry out the measurements regularly at the same time of day, since the blood-pressure
changes during the course of the day.
5.2. Common sources of error
Note: Comparable blood-pressure measurements always require the same conditions! These are normally
always quiet conditions.
• All efforts by the patient to support the arm can increase the blood-pressure. Make sure you are in a
comfortable, relaxed position and do not activate any of the muscles in the measurement arm during
the measurement. Use a cushion for support if necessary.
