11-3 Dispensing in a unit of weight (in mg unit)
Dispensing of a liquid can be performed by weight (mg) instead of volume. (mg unit function)
This function is useful when you handle a liquid that needs to be managed by weight,
such as a diluted solution of a solid or powder. Although the density of a liquid can
vary depending on the sample type and concentration, by weighing the dispensed
amount with an electronic balance and inputting the result into the pipette, it becomes
possible to easily dispense the liquid in a unit of weight (mg).
Selecting the mg unit
The unit (volume: μL / weight: mg) for pipetting can be toggled by the following method.
When the mg unit is selected, the Notice mark blinks and the μL unit is turned off.
* When the unit of weight (mg unit) is selected, perform weight calibration by the
dispensing amount to be used. (The weight calibration data reverts back to the
factory default once the unit is switched toμL.)
