Error Codes Reference
The VitaCheck M1 displays error codes on screen when a measurement cannot be completed or a system issue is detected. Use this reference to identify and resolve errors.
| Code | Description | Action |
|---|---|---|
| E01 | Measurement failed — movement detected | Keep still and silent during the measurement. Rest your arm on a flat surface and try again. |
| E02 | Cuff pressure error — inflation timeout | Check the cuff is wrapped snugly. Ensure the air tube is not kinked. If the cuff is loose, tighten and retry. |
| E03 | Cuff not detected | Check the air tube connection. Push the connector in until it clicks. See: Cuff not detected article. |
| E04 | Excessive pressure variance | The monitor detected inconsistent readings. Rest for 2 minutes and take a new measurement. |
| E05 | Pulse signal too weak | Reposition the cuff — ensure the artery marker aligns with the brachial artery. Tighten the cuff if it is loose. |
| E06 | Cuff over-pressure | The cuff exceeded the safe inflation limit (299 mmHg). The monitor will deflate automatically. Wait 2 minutes and retry. If this recurs, check for tube kinks. |
| E07 | Low battery | Replace all 4× AA batteries or connect via USB-C. Do not mix old and new batteries. |
| E08 | Memory full | The 60-reading memory for the active user is full. Sync your readings via Bluetooth/Wi-Fi to back up data. Oldest readings will be overwritten on the next measurement. |
| E09 | Bluetooth pairing error | Go to Menu › Settings › Connectivity › Bluetooth › Clear Pairings and pair again. |
| E10 | Wi-Fi connection lost | Check your router is online. Verify the monitor is within range. Re-enter Wi-Fi credentials if needed via Settings › Connectivity › Wi-Fi. |
Persistent errors
If an error code reappears after following the recommended action three times, perform a full restart: remove batteries, disconnect USB-C, wait 30 seconds, then reconnect. If the error persists, scan the QR code on your device to contact Monverta support.
