Accuchek make the expert meter.
If you know your carb ratio.. You set up the meter and type in pre meal, carbs you are having and it will tell you how much insulin to give without you having to work it out.
It also 'allows' for your blood test results being high or low when it suggests dosage for food.
It gives good reports too onscreen providing you enetrr whether its pre meal, post meal, bedtime etc.
Its the same as the remote control for the pump they make, but it just doesnt blue tooth to a pump.. You have to manually inject instead.
Its a good meter to have.
