What to do if my Welch Allyn Blood Pressure Monitor shows Err 5 bAtt?
- RRobert TranAug 22, 2025
If your Welch Allyn Blood Pressure Monitor displays 'Err 5 bAtt', it means the power pack or battery voltage is too low, or the batteries are defective, or the battery contacts are corroded. Try replacing the power packs or batteries. If 'bAtt' is displayed during cuff inflation, replace the power packs. Clean corroded battery contacts with a cotton cloth and a little alcohol.
