ECG
The “Check Electrodes” message is displayed on the main unit.
Cause 1
：
An electrode is detached, or is not making good electrical contact with the skin.
Solution
： ・
Check the electrode application.
・
Replace the electrode, or check the lead cable.
Cause 2
：
Even though the “3-lead Override” (ECG Parameter Setup Screen) is set to ON,
electrodes other than L, R, F are connected.
Solution
：
Set the “3-lead Override” to OFF.
Or, detach the electrodes other than L, R, F.
The “Cannot acquire ECG” and “ECG Low Amplitude” messages are displayed on the main
unit.
Cause 1
：
The ECG amplitude is 0.25mV or below for the waveform size of x1, x1/2, x1/4, and
0.150mV or below for the waveform size of x2, x4.
Solution
：
Change the electrode site, or select a lead with higher QRS amplitude.
Caution
：
Using 4-electrode or 5-electrode/10-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
：
Attach the electrodes firmly.
・
If the lead cable or relay cable is defective, replace it.
・
If any noise source is near the patient, move it away from the patient as far as
possible.
Cause 3
：
Even though the “3-lead Override” (ECG Parameter Setup Screen) is set to ON,
electrodes other than L, R, F are connected.
Solution
：
Set the “3-lead Override” to OFF.
Or, detach the electrodes other than L, R, F.
ECG waveform of the main unit contains noise.
The “Artifact” message is displayed on the main unit.
Cause 1
：
The electrode contact is poor.
Electrical blanket or other noise source is near the patient.
Solution
：
Attach the electrodes firmly.
・
If the lead cable or relay cable is defective, replace it.
・
If any noise source is near the patient, move it away from the patient as far as
possible.
Cause 2
：
Myoelectricity is interfering.
Solution
： ・
Change the electrode site to a location where the myoelectricity will be less likely to
interfere.
・
Select “Electrical blanket” for the filter mode.
Caution
：
Selecting “Electrical blanket” mode for the filter mode will decrease the QRS
amplitude and may result in not counting the heart rate.
Cause 3
：
Even though the “3-lead Override” (ECG Parameter Setup Screen) is set to ON,
electrodes other than L, R, F are connected.
Solution
：
Set the “3-lead Override” to OFF.
Or, detach the electrodes other than L, R, F.
