E-F Error Code

E-F Error Code

Mister Mojo here and we’re
gonna talk about the E-F Error.
F means Fill, meaning
you’re not filling the tube
with enough blood.
We’re going see if we can try
and recreate that right now.
So we’re going to wait CH for checking,
the blood icon will flash,
and they just go on like this.
If I don’t get enough on,
you see I didn’t quite
get enough blood there.
It’ll give me an E-F.
So methods to correct.
That is always make sure
that you have a good blood sample size,
about half the size of a matchstick head
just like I have just got right here.
Make sure that you’ve got
warm hands beforehand.
That really helps.
And then quite simply,
let’s do this again.
And you will see what we need to do.
We’re going to place that on the
top having a nice dome rounded
blood sample really really helps there.
And then we just have to
place the tip to it like that.
Come on in.
And within 10 seconds
we will have ourselves
a ketone reading.
1.4, right in the zone!
