Microlife AG1-30 [5/45] Measuring procedure

3BP AG1-30

• Make sure that the cuff is positioned 2 cm above the elbow.

• The artery mark located on the cuff (ca. 3 cm long bar) must

lie over the artery which runs down the inner side of the arm.

• Support your arm so it is relaxed.

• Ensure that the cuff is at the same height as your heart.

6. Any improper setup or damage to the stethoscope will cause

distorted sound or poor sound transmission causing inaccurate

readings.

Proper deflation rate is essential for an accurate reading.

Practice and master a recommended deflation rate of 2-3 mmHg

per second or a drop of 1-2 marks on the manometer

for each

heartbeat.

Measuring procedure

1. Place the chest piece 6 underneath the cuff 2 or 1-2 cm

below it. Make sure the chest piece is in contact with the skin

and lies on the brachial artery.

2. Plug in the ear piece 7 and check, if the chest piece is placed

correctly, so that the Korotkoff sounds appear the loudest.

3. Close the valve 4 on the pump ball 3 by turning the screw

clockwise. Do not over-tighten.

4. Take the pump ball

in your free hand (the arm you are not

using to measure) and pump up the cuff. Watch the pressure indi-

cator on the manometer

and pump up to approx. 40 mmHg

higher than the expected systolic value (the upper value).

• Inflate to 200 mmHg if you are not sure about the expected

value.

5. Open the valve 4 slowly by turning the screw counter clock-

wise whilst holding the stethoscope chest piece 6 on the

brachial artery. Listen carefully as the cuff begins to deflate.

Note the reading on the manometer 1 as soon as you hear a

faint, rhythmic tapping or thumping sounds. This is the

systolic blood pressure reading.

6. Allow the pressure to continue dropping at the same deflation

rate. Note the reading on the manometer 1 as soon as the

thumping sound stops. This is the diastolic blood pressure

reading.

7. Deflate the cuff completely.

8. Repeat the measurement at least two further times and record

your values, date and time immediately after finishing the

measurements.

9. Remove the cuff and the stethoscope.

4. Malfunction / Troubleshooting

If problems occur when using the device, the following points

should be checked and if necessary, the corresponding measures

are to be taken:



If you think the results are unusual, please read through the

information in «Section 1.» carefully.

Description Potential cause and remedy

The sound transmis-

sion is poor, distorted

or there is extraneous

noise.

• Check the ear pieces if they are dirty

or cracked. If not, make sure you

wear them properly.

• Check the tube if it is broken or

twisted.

• Check the chest piece if there is any

damage.

• Make sure the chest piece is in

contact with the skin and lies on the

brachial artery. Clean or replace any

defective parts if found to avoid inac-

curate reading.

The pressure does not

rise although the pump

ball 3 is pumping.

• Make sure that the valve is closed.

• Make sure the cuff is properly

connected to bulb and manometer.

• Check if the cuff, tube and/or bulb is

leaking. Replace the defective parts

if any.

The deflation rate can

not be set to 2-

3 mmHg/sec. by

adjusting the valve 4.

Disassemble the valve from pump ball

to check if there is any blockage in the

airway of the valve. Clean the blockage

and try again. If it still does not work,

replace it to avoid inaccurate readings.

The manometer needle

is not at 0 +/- 3 mmHg

at rest.

• Make sure that the valve is

completely open for zero check.

• If still more than 3 mmHg deviation,

contact your dealer to recalibrate the

manometer.
