It is very important
when you receive your meter or new ketone strips that you calibrate it using the code key. The code key comes in your
bag inside the mesh pocket and to code it, quite simply, you place the code key
into the meter like that. It’ll show CH for checking. And then it will show the same code, 750, that you have on the vial of your strips. In every single box you
will also find a code key. And it’s generally you will find it hidden and tucked to the side of your actual vial in the box itself. Lets get that out and take a look for you. There it is. And this one we will see that this one is 794. The code key imparts the
linearity of the enzymatic batch. This is our way of telling your meter the electrical resistancy
of that enzyme batch which is the reactive agent
for measuring ketones.
