Technical testing procedures

A) Functional testing
Functional testing of the unit can only be per-
formed on human subjects or using a suitable
simulator.
B) Leak testing of the pressure circuit and
error testing of the display
Please note:
a) Prior to testing, separate the cuff from the unit
(after having first removed the screws in the
battery compartment). The air hose connec-
ting plug (special plug) can now be inserted
into the unit.
b) To perform leak testing of the pressure circuit,
a tee connector must be used to connect the
rolled-up cuff and a pump bulb to the pressu-
re circuit.
c) If the pressure in measuring mode exceeds
320 mmHg, the quick-action air release valve
triggers and opens the pressure circuit. If the
pressure in testing mode exceeds 320 mmHg,
the display blinks.
Testing
1. Remove batteries.
2. Hold START-button pressed down and insert
batteries.
3. Release START-button.
The unit is now ready for testing. The displays
of SYS, DIA and PUL now show the actual
pressure.
4. Testing for divergence of Pressure indication
and Density of Pressure circuit (setting time
for cuff at least 60 seconds) can now be
carried out in the usual manner.
5. Switch off unit and reconnect the cuff to the
unit.
C) Security
For security purposes the two parts of the hous-
ing are joined together with a security label.
