5.4 Calibration
Corporate guidelines prescribe that all companies operating with a quality assurance system must regu-
larly calibrate their instruments and equipment. Calibration must ensure that the unit complies with the
stipulated specifications.
When should calibration be carried out?
Calibration relates to the dosing volume of the pump as a function of the tube.
Calibrate;
•
If a new tube type is used and added to the tube calibration store for later use.
•
If using culture media with greatly differing viscosities are used.
•
At regular intervals, e.g. every 3 months.
•
If the silicone tubing flexibility changes and results in a general volume drift. This is based on many
autoclaving cycles, standard tube flexibility loss, age, UV exposure e.g.)
NOTE
The calibration procedure is described in Chapter "Calibration menu".
5.5 Troubleshooting
5.5.1 Overview
The D

P
UMP
1000 software incorporates troubleshooting routines which can be used to correct certain
problems without action on the part of after-sales servicing technicians.
If a problem occurs on the D

UMP
1000, the unit attempts to correct the problem by providing the op-
erator with prompts on the graphical user interface. If these on-screen prompts are followed, the fault or
error can then normally be remedied without action on the part of after-sales servicing technicians.
Each error message with alarm function also contains a description of the fault or error.
