3.6 Temperature
3.7 Invasive blood pressure
Problem Cause What to do
Message ‘TEMPERATURE
ERROR’ Faulty calibration. Perform calibration. If it does not help,
check that front panel connector is
properly connected to STP board.
No temperature displayed Wrong type of probe. Use correct probe.
Temperature out of measurable range. The range is between 10 and 45 °C.
Temperature calibration not protected. Set the protection ON in the Service
Menu.
Problem Cause What to do
Abnormally low pressure Transducer wrongly positioned. Check mid-heart level and reposition
transducer.
No pressure
‘Not zeroed’ message Defective transducer. Check transducer.
No pressure module plugged in. Check the module.
No waveform selected on screen. Check the selected pressure
waveforms by pressing
Monitor
Setup
key and selecting Screen Setup
- Waveform Fields .
Check that the pressure transducer is
open to the patient.
Wrong configuration setting Check the configuration setting from
the STP/Calibrations menu (
Monitor
Setup
- Install/Service - Service -
Parameters ).
Measurement on, channel not zeroed. Zero the channel.
‘Zeroing failed’ message Unsuccessful zeroing of P1 /P2
(number field). Possibly due to pulsating pressure
waveform. Open the transducer to air
and zero the channel.
Offset is > 150 mmHg. Open the
transducer to air and zero the channel.
Defective transducer. Replace it and
zero the channel.
‘Calibration failed’ message Unsuccessful calibration of P1/P2
(number field), possibly due to a
pulsating waveform
Turn the transducer to
sphygmomanometer and try again
(zeroing takes place first).
Gain is beyond the limits (± 20% of the
default gain). Replace the transducer.
