HP IAP 32.1 manual Faults, Monitor operation

7

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.

Warning

The unit cannot be repaired by the user.

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.
