Technical testing procedure
A) Function testing
Function testing of the device can only be performed on human subjects or using
a suitable simulator.
B) Leak testing of the pressure circuit and display error testing
Note: If the pressure during measuring mode increases to more than 320 mmHg,
the quick deflate valve will be activated and the pressure circuit will be opened.
The measurement value display will also blink if the pressure exceeds 320 mmHg
when in test mode.
Testing:
1.) "to open “Test mode” in the “Patient” tab and press the “Start” button.
2.) Aftera short calibration procedure, the device will be in test mode.

if there is no pressure).
3.) Perform the usual tolerance testing of the pressure display and leak
testing of the pressure circuit (take account of the cuff’s minimum settling
time of 30 seconds).
4.) Run test for all four extremities.
5.) Exit test by pressing the “End test” button.
C) Safety
For safety purposes the two halves of the device can be joined together with a
safety seal.
