6.2 Error – Zero calibration of pressure measurement unit
The zero calibration could not be carried out. The measured pressure differs more than 150 mmHg
from the expected value. The sensor is potentially defective. Please check this and repeat the zero
calibration.
The pressure off-set is larger than +150 mmHg or smaller than -150 mmHg. If these limiting values are
exceeded or remained under, no zero calibration can be carried out.
The zero calibration could not be carried out. The pressure has changed by more than 2 mmHg during the
last five seconds. Please check this and repeat the zero calibration.
In order to carry out a safe zero calibration, the variation of the signal shall not be any larger than 2 mmHg
during the zero calibration.
6.3 Internal error – pressure channel
Internal defect in pressure channel PNo. (ART, ICP ...). Remove sensor and use other channel if
needs be!
The error is indicated by an acoustic signal of medium priority and a flashing question mark in the
corresponding field of the overview screen. The text will appear when the Info key is pressed.
An internal test has produced an error. The measuring accuracy cannot be guaranteed anymore. The curve
for this channel is still displayed, but the values are no longer taken into consideration for the trend as they
are unreliable.
By removing and re-connecting the pressure sensor, the test can be initiated again; if it should fail again,
subject the apparatus to an inspection.
6.4 Internal error – temperature
Internal defect in temperature channel TNo. Remove sensor and use other channel if needs be!
TNo. stands for temperature channel T1 or T2, depending on which temperature channel is concerned.
6.5 Memory full
The data memory is almost completely full. Save the data on the PC, otherwise the oldest data will
soon be overwritten.
The error is indicated by an acoustic signal of medium priority and a flashing memory bar. The text rendered
above will be displayed in Info. If the operator is not interested in saving the data, nothing has to be done
at all, otherwise the data should be saved within the next thirty minutes.
6.6 Residual operating time – battery pack
The anticipated remaining life of the rechargeable battery is only XX minutes. Please recharge
immediately!
If the apparatus is not switched off at the end of the remaining of XX min (e.q. 29 min) operating time or if
no mains adapter is connected, the apparatus is switched off at the end of the remaining operating time. In
this case, a continuous sound will be released for at least 30 seconds (typically one hour). As soon as the
mains adapter is connected this warning sound will turn off. If no mains operation is possible, switch on the
apparatus and off again after a few seconds. Avoid a longer period of storage in discharged condition.
6.7 Pressure sensor has been removed
The pressure sensor PNo. or pO2 sensor have been removed. Confirm this with OK. If you have not
removed the sensor, the cause is most probably a sensor defect. Please check this and swap the
sensor, if needs be!
PNo. stands for pressure channel P1 or P2, depending on which pressure channel is affected.
