Chapter 8 Troubleshooting
8.1 Auto shutdown
 The battery is almost running out, which causes overdischarge protection circuit action.
 The voltage of AC power supply is too high, which causes overvoltage protection circuit
action.
8.2 AC interference
 Whether the device is grounded reliably?
 Whether the electrode or lead cable is connected correctly?
 Whether the electrodes and skin are daubed with enough conductive paste?.
 Whether the metal bed is grounded reliably?
 Whether the patient is touching the wall or metal parts of the bed?
 Whether the patient touches other people?
 Whether there is high power electric equipment working nearby? Such as X-ray machine
or ultrasonic device, etc.
Note: If the interference can not be removed after taking above measures, please use a
AC filter.
8.3 EMG interference
 Whether the room is comfortable?
 Whether the patient is nervous?
 Whether the bed space is narrow?
 Whether patient speaks during recording?
 Whether the limb electrode is too tight?
