Hello ! I was forced to use a blood pressure monitor Microlife BP 3AG1. Proper pressure cannot be built up in the cuff. After a while, the measurement shows the error: ERR 3 I changed the batteries, then also and connected the power supply. And the measurement result still shows error: ERR 3 ....

Are you sure that the cuff is ok, i.e. 100% tight? With this message, 99% of damage is due to cuff leakage. The easiest way is to check it by pumping it up to a certain degree, and then clamp (bend) the hose, if it becomes flak after a short time - the cuff needs to be replaced. It also happened to me that the cuff socket in the camera broke, the effect was similar.

This error appears when the sleeve from the blood pressure monitor is put on the arm, or does it fly (pump) when empty? As empty without a hand, the error will always be on everyone.

Hello ! I went with the above blood pressure monitor to the medical store. There, on the spot, a very nice lady took a new cuff off the shelf and checked the blood pressure monitor. diagnosis; cuff unsealing. Buying a new cuff PLN 19. Regards !

Hello !
I was forced to use a blood pressure monitor Microlife BP 3AG1.
Proper pressure cannot be built up in the cuff.
After a while, the measurement shows the error: ERR 3
I changed the batteries, then also and connected the power supply.
And the measurement result still shows error: ERR 3 .
For subject matter experts.
Could the pressure valve be damaged? And where can I buy it?
I am attaching his photos.
