Why does my Spengler LeECG Medical Equipment show AC interference?
- G
  Gabriel RodgersAug 14, 2025
  AC interference on your Spengler Medical Equipment, presenting as a 50Hz sine wave overlap with amplitude and jitter on the ECG baseline, can stem from several factors. Ensure the device and patient bed are properly grounded. Verify correct electrode and leadwire connections, and sufficient conductive paste application. Avoid patient contact with conductive objects and nearby powerful electrical equipment. Confirm the patient isn't wearing metal ornaments and the AC filter frequency is correctly set. If issues persist, utilize an AC filter, noting it may slightly attenuate the recorded waveform.

What to do if my Spengler Medical Equipment displays baseline drift?

  Tami MillerAug 18, 2025
  If your Spengler Medical Equipment shows baseline drift (irregular up and down movement of the printed ECG baseline), check that the electrodes are firmly attached and the lead wires are properly connected. Ensure the electrodes and the patient's skin are clean, and that enough conductive paste is applied. Also, consider whether the patient moved or breathed during recording, and avoid mixing old and new electrodes. If the problem persists, use an ADS filter.

What to do if Spengler LeECG Medical Equipment displays 'XX lead off'?
- T
  Terri Young PhDAug 21, 2025
  If your Spengler Medical Equipment displays 'XX lead off' (all leads off), follow these steps: 1. Check the electrodes and lead wires, re-applying electrodes or reconnecting wires if needed. 2. Ensure the patient cable is properly connected to the device. 3. If waveforms are still absent, assess if the device is inoperable due to amplifier overload or saturation.

Why is the ECG waveform out of the grid area on my Spengler Medical Equipment?
- K
  Keith BrooksAug 25, 2025
  The ECG waveform may be out of the grid area on the printing paper of your Spengler Medical Equipment due to great fluctuation of the waveform. Set the sensitivity to "Auto". The device will automatically adjust the sensitivity according to the amplitude of the ECG signal.

How to fix Spengler Medical Equipment when some lead without waveform printout?
- L
  Lori DavisSep 3, 2025
  If you acquire ECG data immediately after applying leadwires to the patient with your Spengler Medical Equipment, the ECG traces may not display because the ADS is not stable yet. Wait for the waveform of each lead to stabilize with good contact before ECG measurement.

What to do if Spengler LeECG Medical Equipment export failed?
- L
  Lisa HarrisSep 6, 2025
  If the export fails on your Spengler Medical Equipment, check the USB device and try exporting the data again.
