Attention
Measurement errors

Although the ABPM 7100 meets all EMC standards, you should nonetheless avoid exposing it to
strong electromagnetic fields, as this may cause malfunctions outside the tolerances for the device.
You should therefore ensure that the ABPM 7100 is at least 30 cm (12 inches) from any portable RF
communications equipment.

The cuff tubing between the ABPM 7100 and the cuff may not be knotted, compressed or pulled apart.

The cuff connection must always engage with an audible "CLICK". A loose connection between the
tubing and the device leads to measurement errors.

Note Severe malfunctions are indicated by a continuous beep.
 In the event of a continuous beep, switch off the device, remove the cuff and inform your
doctor.
24-hour measurement
1. Before a 24-hour measurement, go through these instructions together with your doctor.
2. Let your doctor explain possible hazards in detail on the basis of the warnings above.
3. Ensure that you have understood all functions and observable points.
4. Turn the device off when it is not being worn (e.g. during x-ray screening at airports). When the device
is applied again, ensure that it is turned on with the ON/OFF button.
Safety:
For your own safety during the following steps, please observe the safety instructions at the
start of this chapter.
Position of the cuff
It is imperative that the artery symbol is positioned on the brachial artery. If the cuff is aligned correctly, the
metal bar will lie on the outside of the upper arm (on the elbow side), whereby the fabric bag must cover the
skin under the metal bar.
The Buttons
ON/OFF
The ON/OFF button turns on and off the ABPM 7100 when the button is pressed for more
than 2 seconds.
START
The START button serves to
 initiate the automatic protocol.
 trigger a measurement in addition to the automatic protocol.
DAY/NIGHT
The DAY/NIGHT button is used to differentiate between waking and sleeping phases during
the measurement. Press the DAY/NIGHT button immediately before going to bed and upon
waking.
EVENT
Press the EVENT button to record an event which may affect the blood pressure and to
trigger an additional measurement. Note the reason for pressing the EVENT button in the
event log.
Measurement process
During the first measurement, the cuff is inflated in increments, to determine the cuff pressure required to
measure the systolic blood pressure value. This maximum required inflation pressure is stored and applied by
direct inflation during the subsequent automatic measurements. The patient should stay calm during the
measurement process, until the measurement is completed. Allow your arm to hang loose, or place your lower
arm loosely on the table or on a support whilst sitting. Avoid any movement! In the event of a failed
measurement a new measurement is performed automatically according to the measurement process
described above.
Cancelling a measurement
A measurement will be cancelled by pressing any buttons during the measurement process causing the cuff
to be quickly deflated automatically. The LCD display will then show "-StoP-" and the ABPM 7100 will beep 5
times. This cancellation will be stored in the measurement value table under Cancel.
