Err 5
An average value could not be calculated due to unstable conditions while the
readings were being taken.
Repeat the measuring process, keeping your arm still and not speaking.

it impossible to obtain a final result.
Read through the checklist for performing reliable measurements and then
repeat the measurement.

Repeat the measurement.
