Follow below pipettes calibration procedure:
1. Press < Select pipette> key;
2. Select a pipette for testing from displayed list;
3. On selecting, the software returns to the main window, and name of
selected pipette is visible in the grey coloured workspace;
4. Press < Start> key in the bottom bar of the display;
5. If option is enabled (set to ) a window is
opened for inserting the batch number, and accepting the value;
6. A window is opened for inserting values of ambient conditions parameters
read from the external sensors (temperature, humidity, pressure and
water temperature), on inserting press < Accept> key;
If option is enabled (set
to , the software automatically acquires data from the THB module
on temperature, humidity and atmospheric pressure. The value of water
temperature has to be inserted manually, and confirmed by pressing <
Accept> key;
7. The software returns to the main window, and the grey coloured
workspace displays the following data: tested volume and process status
. The task bar displays commands and hits for a user on the
following step - . Description of texts: C1 –
channel number; V1 – number of volume for a channel; N1 – number of
measurement for tested volume;
8. Follow displayed commands until completing the calibration process. The
grey coloured workspace displays other data on calibration process, i.e.
average volume, values of errors, specific for carried out process;
9. On accepting the last measurement, a window is displayed with ambient
conditions parameters. Proceed as on process start and insert all ambient
conditions parameters, and press < Accept> key;
10. The software automatically generates a report, that is printed and stored
in the database of reports from pipettes calibration (ambient conditions
and water temperature values given in a report are averages from the
initial and final values of a process);
11. Complete the process by pressing < > key visible in the bottom bar.
In case of multichannel pipettes, the balance displays a message on
continuing the process for the following channels. On confirming the
message, the balance carries out calibration / testing process for the
following channel. The settings remain unchanged;
12. The software enables starting the following procedure for the same
pipette or selecting another pipette from the database.
23.6. Report from completed calibration processes
On completing each calibration process, a report is generated. The report is
saved in a database < Reports from pipettes calibration
processes>. The files are named by their date and time (hour) of
calibration process.
