What to do if Contec Medical Equipment shows too large interference, disorderly waveform?
If you are experiencing large interference and a disorderly waveform, check the lead cables, grounding cable, and power connections to ensure they are reliably connected. Also, if the patient is nervous and cannot keep quiet, try to treat the patient well to calm them.
What to do if Contec Medical Equipment shows not regular waveform, large up-and-down, beeline figure?
If the waveform is not regular and shows large up-and-down movements or a beeline figure, try the following: Use high-quality alcohol to improve electrode conductivity. Charge the battery if the capacity is low. Clean the electrode slices and the skin below them with alcohol to improve the connection. Ensure that the lead cables are firmly connected to the device's plug, and that the electrodes are properly connected to the lead cables.
Why does my Contec Medical Equipment have a baseline burr?
A baseline burr may be due to large AC interference or the patient being nervous, leading to large EMG interference; in both cases, try to amend the environment. Also, if the bed is made of steel, replace it. Ensure that the power cable and lead cables are not parallel or too close to each other.
What to do if Contec Medical Equipment has a baseline draft?
If there's a baseline draft, it could be due to low power; in this case, charge the battery. Alternatively, the patient's movement could be the cause, so ensure the patient remains still.
How to fix unclear waveform on Contec Medical Equipment?
If the waveform is unclear, the printer head surface may be dirty. If there's a power cut, clean the printer head with alcohol and wait until it is dry before printing. Alternatively, the thermal paper could be the problem, so replace it with the specified thermal print paper.
