Quality control
A regularly carried out quality control is the best monitoring system for reliable test results. For
making sure that the results of the control probe and of the unknown probe are evaluated
under the same test conditions the control material should be included in every test run. The
recommendations of the reagent manufacturer concerning the quality control should serve as a
guideline for the quality control report. If the control results are out of the stipulated ranges this
could be a hint for a system error of which the cause should be investigated immediately.
Frequent sources of error and instructions for the troubleshooting are listed in chapter 10.1
“Analytical errors”.

Maintenance
9.1
Maintenance by user
The rotation speed, the power of the magnet sensor and the temperature of the analyser have
been calibrated by the manufacturer before delivery. It is recommended to check the
temperature of the measuring / pre-heating block periodically with a usual calibrated
thermometer. The turning speed of the measuring cell can as well be checked from time to time
with a calibrated (stop) watch.
A general cleaning is the only maintenance procedure that has to be carried out regularly. It is
recommended to clean the instrument from time to time with a damp cloth for removing dust
and other materials. Blood, serum and reagent residues should be removed immediately.
Reagents can cause corrosion. Liquids that have been spilled over the pre-heating station or the
measuring cell must be removed at once. Spilled samples have to be considered as potentially
bio-hazardous and must be removed immediately in strict compliance with the appropriate
safety precautions for avoiding a contamination of the personnel. If a decontamination of the
MC 10
plus
is required wipe off the area in question with a paper cloth which is moistened with a
mild disinfectant.
In addition to this there are no routine maintenance procedures for the MC 10
plus
.
Ball that fell erroneously into the station can be removed easily by means of a magnet.
