4.2. Using an AC power adapter (special accessory sold separately. Call 1-800-568-4147 to order)
It is possible to operate this blood pressure instrument with an AC adaptor (output 6 V DC / 600 mA with
DIN plug). Make certain that you use an adaptor which fulfils the legal requirements and electronic
requirements in the U.S. (UL standard)
a) Push the plug into the socket on the back side of
the instrument.
b) Push the AC adaptor into a 110 V power
socket (U.S. or Canada).
c) Test that power is available by pressing the
START button.
Note:
• No power is taken from the batteries while the AC adaptor is connected to the instrument.
• If the power is interrupted during the measurement (e.g. by removal of the adaptor from the wall
socket), the instrument must be reset by removing the plug from the instrument.
• Please consult Microlife if you have questions relating to the AC adaptor.
4.3. Tube connection
Insert the cuff tube into the opening provided on the left
side of the instrument, as shown in the diagram.
5. Measurement Procedure
Please note: You should always be seated before and during measurement
5.1. Before the measurement:
• Avoid eating and smoking as well as all forms of exertion directly before measurement. These factors
influence the measurement result. Find time to relax by sitting in an armchair in a quiet atmosphere for
about ten minutes before measurement.
• Remove any garment that fits closely to your upper arm.
• Always measure on the same arm (normally left).
• Always perform measurements at the same time of day, since the blood pressure changes during the
course of the day.
