In order to continue adding process, press
button on printing out the sum. Home screen of the
main mode is displayed.
If samples are measured with packagings, load the weighing pan with the packaging, wait for
stabilization and press
button.
CAUTION: for ADDING mode, on pressing
button (confirming mass of measured sample) data
connected with the measurement is printed. The following data can be printed: Measurement
number, NET mass (in calibration unit), TARE mass (in current unit), GROSS mass (in current
unit), and current result (in current unit). Data to be printed is to be set in GLP PRINTOUT
parameter - see point 8 of this user manual. Other information (except the above-listed), such as:
USER, PRODUCT, DATE, TIME, VARIABLE 1, VARIABLE 2, CALIBRATION REPORT, NON-
STANDARD PRINTOUT are not printed.
11.14. PIPETTES CALIBRATION
Caution! Function valid for AS R series balances exclusively.
Pipettes calibration function applies to fixed volume pipettes and adjustable volume pipettes. During
volume testing procedure, the software determines accuracy and repeatability errors. In case of
pipettes with adjustable volume, errors for Max, Min and ½ Max volume are estimated.
All pipettes are tested for adherence to requirements of PN-EN ISO 8655:2003. During the tests
dosing repeatability and accuracy are monitored.
In order to ensure the highest accuracy of pipettes calibration process, maintain the following
ambient conditions at a workstation:
•
Ambient temperature of a pipette, tips and liquid should be kept between 20°C - 25°C with
change rate during testing within ± 0.5°C,
•
Relative humidity 50 - 75%;
and
•
Use distilled water for pipettes calibration processes,
•
Make sure that a pipette, tips and distilled water are thermally stabilized in the room intended
for weighing operation performance. The reference standard advises that minimum
acclimatization time for above mentioned is 2 hours.
