• 1-point adjust.
After you input the density, the selected volume and the corresponding weighing
result, the pipette will determine a correction factor. The factor is only correct for the
selected volume and the selected work technique. However, the factor is used for the
entire volume range of the pipette. You must carry out a gravimetric test to check the
validity of the factor.
• 2-point adjust.
After you input the density, two different volumes and the corresponding weighing
result, the pipette will determine a correction factor. The factor is only correct for the
selected volume range and the selected work technique. However, the factor is used
for the entire volume range of the pipette, i.e., below and above the two measuring
points as well. You must carry out a gravimetric test to check the validity of the factor.
• 3-point adjust.
After you input the density, three different volumes and the corresponding weighing
results, the pipette will determine two correction factors. The factors are correct from
measuring point to measuring point in the selected volume regions and for the
selected work technique. The respective factor is, however, also used below and above
the first or third measuring point. You must carry out a gravimetric test to check the
validity of the factors.
5.19.9.1 Activating the Pswrd. protection (Xplorer plus)
You can protect the adjustment using a four-digit, numerical password. The password for
the Edit mode and the Adjustment option can vary. The password can be changed or
deactivated after it has been entered. If you lose your password, please contact your local
Eppendorf distribution partner or reset the pipette to the factory settings.
1. Press the rocker upward to activate the password protection.
ON appears in the display.
2. Press the Select softkey.
3. Use the rocker to select the digit.
4. Press the Next softkey to switch to the next field.
5. Enter data in all of the fields.
6. Press the Save softkey to save the password.
7. Reenter the password after completing the saving procedure.
8. Press the Enter softkey.
Password protection is active.
If an adjustment other than factory settings is applied, a gravimetric test of the
pipette must be carried out first. This is the only way to ensure that the selected
adjustment meets requirements regarding errors.
The adjustment can no longer be changed if the password has been lost.
