Troubleshooting
This section explains the troubleshooting for each case.
ECG
The “Check Electrodes” message is displayed.
Cause
: The electrode is detached, or is not making good electrical contact with the skin.
Solution :
・
Check if the electrodes are properly attached.
・
Replace the electrode, or check the lead cable.
The “ECG Failed” message is displayed.
Cause 1 : The ECG amplitude is 0.25mV or below for the waveform size of
×
1,
×
1/2,
×
1/4, and
0.150mV or below for the waveform size of
×
2,
×
4.
Solution : Change the electrode attachment site, or select the lead with higher QRS amplitude.
Note
: Using 4-electrode or 5-electrode instead of 3-electrode allows more accurate QRS
detection.
Cause 2 : The electrode contact is poor.
Electrical blanket or other noise source is near the patient.
Solution : Electrical blanket or other noise source is near the patient.
・
Replace the lead cable if defective.
・
If any noise source is near the patient, locate it away from the patient as much as
possible.
ECG waveform contains noise.
The “Artifact” message is displayed.
Cause 1 : The electrode contact is poor.
Electrical blanket or other noise source is near the patient.
Solution : Attach the electrodes firmly.
・
Replace the lead cable if defective.
・
If any noise source is near the patient, locate it away from the patient as much as
possible.
Cause 2 : EMG is interfering.
Solution :
・
Change the electrode site to a location where EMG will less likely to interfere.
・
Select ESIS for the filter mode.
Note
: Selecting ESIS for the filter mode will decrease the QRS amplitude and may result in not
counting the heart rate.
The “ECG Unit Error” message is displayed.
Cause
: A communication error with the ECG measuring unit exists.
Solution : A broken wire or failure of the ECG unit can be considered.
Contact our service representative.
The measured data is displayed as “
×××
”.
Cause
: The heart rate is outside the measurement range.
Solution :
・
Check the electrode application.
・
Replace the electrode, or check the lead cable.
