Printouts option enables you to determine content of a particular standard printout, and to define non-
standard printout.
Standard printout comprises four internal blocks, each containing different variables.
settings: YES – print; NO – do not print..
Settings for header, GLP, and footer printouts are specified in section 14.7. For settings of pipettes

24.5. Pipettes Calibration Start-Up

In order to carry out pipettes calibration process you need a special adapter, the adapter does not
come standard with the balance.
The adapter facilitates piston pipettes calibration and/or verification, it is intended for 3Y and 4Y
balances.
The adapter has been designed to minimize evaporation occurring in the course of liquids weighing.
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 is conditioned by calibrated pipettes type.
Prior pipettes calibration start, install the adapter inside of the weighing chamber, next enter data
regarding pipettes that are to be calibrated, include complete pipette characteristics and values of
errors (see: Pipettes Database).
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 read section 24.1 of this user manual.
With all parameters set, you can start pipettes calibration.
