10.5 Troubleshooting
Trouble
Possible Reason
Solution
Big interference;
Random waveform.
The baseline possess
the burr.
The waveform is not
Regular;
Big undulation,
Right line.
Baseline drift.
The waveform is not
understand.
1. V1. It is firm whether
the grounding connections.
2. The joint of two sides of
conductance line is not stable.
3. AC interference.
4. The patient from irritation
or excitement.
1. AC interference is big.
2. The patient excitement,
EMG interference is big.
1. Electrode electric
conductivity is not good.
2. The batteries are drained.
3. The electrode is loose
contact against skin.
4. The joint line and leader’s
plug part is not connection
enough.
5. The connection between
patient cable and electrodes
is not well.
1. The batteries are drained.
2. Patient moves.
1. There is the filthy matter
in the print head face.
2. Paper problem.
1. Checking ECG leaders,
grounding, and Power
source.
2. Please make sure the
patient is calm.
1. Improvement
environment.
2. If iron and steel bed,
Need change.
3. The power source line
and joint line of the ECG
machine is non- parallel
or too near.
1. The alcohol of use is
asked for well.
2. Use ethyl alcohol to wash
electrode wafer and the skin
under the electrode.
3. The battery has run out,
please charge the lithium
battery.
4. The electrode reed tightly
clip.
1. Be charged to the battery.
2. Keep patients quietly.
1. The situation of the power
off Wash print head by
alcohol,it may be print after
the alcohol has volatilized.
2. Replace thermal paper
which assigned.
