Hey guys
i have a Herpstat 2 that I bought less than 2 months ago and it was working good
bug today when i checked my BPs rack i noticed that the power is changing constantly,
it goes from
40% to 80% and from 80% to 100% and then it goes all the way back to 0% its marking all this in less than a minute
is it normal that my herpstat is acting like this or is something wrong ??
please help mee
