How to fix too large interference in Gima ECG90A?
- H
  Heather RiveraAug 8, 2025
  If you're experiencing too much interference resulting in a disorderly waveform with your Gima Medical Equipment, it could be due to several reasons. The grounding cable or lead cables might not be connected reliably. There could be AC interference present, or the patient might be too nervous to remain still. To resolve this, check the power cord and lead cables to ensure they are properly connected. Additionally, allow the patient time to prepare for the measurement to reduce nervousness.

Why Gima Medical Equipment displays baseline burr?
- K
  Kimberly WileyAug 15, 2025
  If the Gima Medical Equipment displays a baseline burr, it may be due to large AC interference or the patient is nervous, leading to significant EMG interference. Try to improve the environment where the equipment is being used. If the bed is made of steel, consider replacing it. Also, ensure that the power cable and lead cables are not parallel or too close to each other.

What to do if Gima ECG90A has unclear waveform?
- B
  Brandy CruzAug 22, 2025
  If the Gima Medical Equipment's waveform is unclear, there are a few potential reasons. The battery might be low, the printer head surface could be dirty, or there might be an issue with the thermal paper. Try charging the battery first. If that doesn't solve the problem, cut off the power and clean the printer head with alcohol, then let it air dry. If the issue persists, replace the thermal print paper with the specified type.

Why does Gima ECG90A Medical Equipment show baseline draft?
- S
  Samantha ShepardAug 30, 2025
  If the Gima Medical Equipment shows a baseline draft, it could be due to low power or patient movement. To address this, charge the battery and ensure the patient remains still during the measurement.
