    Default Doser 2.1 unable to dose 0.1ml

    I am not able to dose anything lesser than 1 ml, both automatic or manual dosing. I have tried changing the speed to 0 and 1, but still can't dose 0.1 ml (or 0.9 ml).

    Is mentioned in the specification that doser 2.1 can dose 0.1 ml. Please advise.

    Some more details would greatly be apreciated.

    Does the doser deny to dose this amount or can't you enter the value in GCC?

    Slave or Standalone?

    Firmware?

    etc.?

    I can enter the decimal value, eg. 0.1 ml but system will not dose when it reaches the time to dose for automatic dosing. For manual dosing, when enter amount with decimal, when click "OK", no reaction on doser. And when amount changed to 1 ml, it dosed.

    Mine is Standalone and firmware is 1.24.

    do you use the slowest speed for this extreme small amount?

    has the doser been calibrated at this speed?

    do you use newest GCC?

    Yes I have calibrated the pump at 0 speed at 8.5 ml/min. When dosing at 0.5 ml per dose per day, pump didn't dose at the dosing time scheduled. Even dose manually using "dose specific amount", it doesn't dose when click OK (no reaction) for anything less than 1ml.

    I have tried both GCC (10.9.1) and myGHL.com also same (doesn't dose).

    Is this a common problem or just my unit?

    It will not dose under 1ml if the correct settings have not been entered. Please post a screenshot of the dosing schedule settings.

    I already did the setting as per Matthias advice. Because it doesn't dose lesser than 1 ml, so I have no choice but to change to 1 ml per dose.

    Just wondering, did you check the time settings on the doser?
    If the doser's time is off, it may be dosing that 0.1mL at a time you're not looking?

    Yes, the doser time was set correctly (on the overview print screen). I can see the doser dose when I changed it to 1 ml but not 0.1ml.
