14.5 Troubleshooting List
Disturbance too
big, the
waveform is in
disorder
1.Whether the ground cable proper.
2.The connection of leads is not stable.
3.Whether there is disturbance from
alternating current.
4.Patient is nervous
1.Please check the lead, ground
cable and power supply.
2.Please dispose the patient in
proper state.
1.Disturbance from alternating current is
too fierce.
2.Patient is nervous and the disturbance
of EMG too strong
1.Change a comfortable
environment for patient
2.If the sickbed is metal, please
change it.
3.The power line and lead is not
parallel or too close.
Wave form is
not regular, with
too great wave
or beeline
1.The conductivity of electrode is not
well.
2.Power of battery is used up
3.Contact between electrode and skin is
not proper.
4.The plug between lead and main unit
is not tight.
5.The contact between lead and
electrode is not proper.
1.Use alcohol of high quality.
2.Clean the electrode and patient’s
skin where touch the electrode.
3.Charge the battery.
4. Keep the electrode reed clamping.
1.Power of battery is used up.
2.Patient is moving.
