5.2.1 Execution Procedure for Measurement
Inspection ABPM
•
Reference pressure instrument (accuracy
≤
0.8 mmHg)
•
Measurement chamber with 500 ml volume (rigid metal
vessel, e.g. art. no. 7703090)
•
Syringe 50 ml (for pressure build-up)
•
Stopcock system incl. tubing (e.g. art. no. 770203A)
•
Pressure tubing
Activate the ABPM Maintenance menu with the ABPM
Maintenance key in TSM Service Program, TL Manual Test and
Calibration.
The ABPM Maintenance menu is used for the function test of
the Dialog automatic blood pressure measurement ABPM option.

1.
Connect all components according to figure (set stopcock
system according to figure).
2.
Switch on Dialog in TSM service program.
3.
Select in TSM Manual Test and Calibration, TTL Manual Test
and Calibration and then ABPM Maintenance.
4.
Press
button.
Wait until a pressure build-up of approx. 170 mmHg (start of
pressure retention phase).
5.
Increase the test pressure to 290 mmHg (
±
10 mmHg) with
the syringe. Read the value displayed on the Dialog and close
stopcock 4 immediately. Now read the value on the reference
instrument and enter in table.
6.
Decrease pressure according to test points and enter values in
table.
7.
Enter deviations in table.
