HP (Hewlett-Packard) IAP 32.1 Computer Monitor User Manual


 
Monitor operation
After placement of probe the tube
connector is inserted into the
monitor socket and fastened by a
slight clockwise turn. The soft
material of the connector
guarantees airtightness.
Pressure measurements are started
by switching on the monitor. No
manual zero adjustment or
calibration is required.
Faults
The air-tightness of the air-pouch
system is checked regularly. If a leak
is detected, the red warning
indicator shows alarm. When the
leak is removed the red warning
indicator disappears and the
measurement is continued. If the
leak has not been removed after
one minute, in addition to the alarm
display a chirp sound is emitted. To
reset the alarm the monitor must be
switched off and on again. The
chirp sound stops after one minute,
unless the monitor has been
switched off before, and the digital
display dissapears. The warning
indicator continues to flash.
If a pressure limit is exceeded during
probe filling the filling process is
interrupted, the digital display
shows ´E1´ and the chirp sound is
emitted. This can happen if the air-
pouch resists unfolding or if the
tube is clamped. Switching off and
on the monitor resets the system.
If the digital display shows ´E2´ or
´E3´ during operation an internal
fault has been detected. Contact
the service in this case.
