Eppendorf Xplorer® (plus) — Operating manual

Regularly check the precision and accuracy of the Xplorer pipette to prevent dispensing errors.
You can use the "PICASO" software, version 2.3.18 or higher, to determine the maximum
permissible systematic and random errors. If the pipette is used at a location with an extremely
high altitude, it must be adjusted to the ambient air pressure (see Adjustment on p. 45).
No spring loading action of the
tip cone when taking up pipette
tips. Spring-loading action is blocked by a
locking ring.  Remove the locking ring again.
Use a 5 mL or 10 mL single-channel
pipette or 1 200 μL multi-channel pipette. No remedy. The tip cone of these sizes do
not have spring loading action.
The rechargeable battery is heavily
discharged. Confirm the message with the OK softkey.
Complete the dispensing operation as
quickly as possible and charge the
rechargeable battery for 3 hours. You can
continue dispensing with the power supply
connected. Then charge for an additional
3 hours.
The rechargeable battery is almost
completely discharged. The remaining
rechargeable battery capacity is only
sufficient for displaying the information to
the left. Dispensing cannot performed. The rechargeable battery must be charged
for at least 15 minutes before further use.
A charging time of 3 hours is
recommended.
The following message
appears briefly before the
aspiration:
Selected volume not possible
with stored adjustment!
A factor that was determined during the
Xplorer adjustment leads to a very high
stroke increase. This high stroke increase
limits the dispensing volume.  Confirm the error message with the OK
softkey.
The situation can only be remedied by
changing the adjustment.
 Make sure that you are authorized to
carry out the adjustment.
The following message
appears briefly for the selected
volume:
Volume limit XXXX μL/mL
The Volume limit option was used to limit
