24.5. PIPETTES CALIBRATION START-UP
In order to carry out pipettes calibration process you need a special adapter which is non-standard
balance equipment. The adapter facilitates calibration process and/or piston pipettes check and it is
intended for 3Y and 4Y balances.
The adapter has been designed to minimize evaporation occurring in the course of weighing liquids.
It comprises a mini weighing chamber installed inside the weighing chamber of a balance, an
evaporation ring and a dedicated weighing pan enabling to locate a measuring vessel in the very
centre.
Application of the adapter prevents risk of liquid evaporation during the calibration process. Compact
dimensions of the adapter along with use of the evaporation ring enable maintaining high humidity
rate inside the weighing chamber.
Carried out research has proved that the adapter eliminates or considerably reduces liquid
evaporation process. Eliminated/reduced liquid evaporation is a key factor while calibrating piston
pipettes by means of a gravimetric method.
Selecting an appropriate adapter and balance mostly depends on calibrated pipettes type.
Prior pipettes calibration start install the adapter inside the weighing chamber, next enter data
relating to pipettes that are to be calibrated, include complete pipette characteristics and values of
errors (see: Database of Pipettes).
Now set pipettes calibration parameters:
•
Measurements quantity
•
Request serial number (YES/NO)
•
Operation with adherence to ISO 8655 (YES/NO)
•
Upload ambient conditions parameters from THB module (YES/NO)
Caution:
For parameters and settings overview go to section 24.1.
Pipettes calibration procedure:
1. Press <
Select pipette> button.
2. List of pipettes is displayed, select a pipette for testing.
3. Pipettes calibration home screen is displayed, selected pipette name is visible in INFO field.
4. Press <
Start> button located in the bottom bar.
5. With <YES> parameter set for <Request serial number> parameter a window for entering batch
number opens. Enter the value, next press <
> button for confirmation.
6. Window for entering ambient conditions values is displayed, read the temperature, humidity
and pressure from external sensors and enter them, next press <
> button for
confirmation.
With <YES> parameter set for <Upload ambient conditions parameters from THB module>
parameter the temperature, humidity and pressure values are acquired automatically from the
