設定微量調節器。當設定移液器的容量時，應該始終向下調整到所需的容量。透過向下調整，你可以減少微量調節器機構內部機械回程間隙的影響，從而確保更高的準確度。 但當要將容量從較低設定增加到較高設定時，請將容量調節旋鈕至少先轉到比所需設定高出三分之一圈的位置。然後再慢慢向下調整到正確的容量。
When setting the micrometer on a pipette, always "dial down" to the desired volume. By doing do, you ensure better accuracy by reducing the effects of mechanical backlash or slippage within the micrometer's gears.
