Cause 1
Electrode is detached.
Solution
Reattach the electrode. If the electrode contact is poor, replace the electrode.
Cause 2
The lead cable is disconnected from the electrode terminal.
Solution
Securely connect the lead cable.
Respiration
"0" is displayed for respiration rate
Cause
The amplitude of the respiration waveform is too low.
Solution
Change the electrode site, or select a lead with higher QRS amplitude.
SpO2 Measurement
The pulse waveform is not displayed, or interrupted
Cause 1
The amplitude of the pulse waveform is too low, or the sensor is not positioned correctly.
Solution
Check that the light emitting and receiving parts of the sensor LED are aligned.
Cause 2
The sensor is defective.
Solution
Replace the sensor.
Cause 3
SpO2 sensor is not firmly connected to the connector.
