18 Pipette calibration ("PIPETTE")
18.1 Introduction to pipette calibration
Quality management systems require volumetric measuring equipment to be checked regularly. This
application allows you to check pipettes of any make by means of a gravimetric method.
You require a thermometer and a barometer in order to conduct this.
During the pipette test, the sample volume is always derived from the sample weight. The density of the test
liquid (distilled water) and the buoyancy are taken into account during conversion.
The pipette application supports up to 20 pipettes. By simply selecting the pipette you require, its
specifications are loaded into the application. You can then commence the pipette test straight away.
The pipette specification data must be defined once beforehand in accordance with the manufacturer's
details. You can change this at any time later on.
If you wish to adjust the pipette, please consult the pipette manufacturer's instructions.
18.2 Selecting the pipette calibration application
In order to activate pipette calibration, press the «
MENU
» key and select the "PIPETTE" application.
18.3 Configuring the pipette calibration
In the "SETUP APPLICATION" menu, specify the measuring sequence and define the pipettes. The
tolerances for inaccuracy and imprecision are manufacturer and model-specific. Refer to the pipette
manufacturer's documentation for data.
