8.1 Cleaning Information
The R&S QAR and its accessories are sensitive devices. Clean the R&S QAR in an
appropriate manner to prevent the components from getting damaged.
Cleaning the R&S QAR panel
1. Clean the front side of the R&S QAR panel only if necessary (visible dirt particles).
If cleaning the front side becomes necessary, do so carefully with a dry, lint-free
duster or a vacuum cleaner with a soft attachment.
The cover attached to the front side is sensitive to mechanical influences and can
break if you apply too much pressure.
Do not use liquids to clean the front side. Using liquids on front side of the
R&S
QAR can lead to inaccurate measurements.
2. Clean the frame and rear side of the R&S QAR with a lint
‑
free duster. In the case of
stubborn dirt, you can also wipe the frame and rear side with a damp rag.
3. Clean the platform using a broom or vacuum cleaner.
Remove any stubborn dirt using a damp rag. A neutral, non
‑
abrasive cleaning
agent can be added to the cleaning water.
While cleaning the platform, take care not to damage the front side of the panels.
Make sure that the platform does not become too wet during cleaning. Too much
liquid can damage the base. Any escaped liquid (including water) must be removed
immediately.
Never clean the platform with a floor cleaning machine.
Cleaning the mounting equipment (R&S QAR-Z50, -Z61 and -Z42)
1. Before cleaning the mounting equipment, remove the measuring equipment like
the cables, the transmitter module or the reference reflector. If this is not possible,
do not touch the measuring equipment. The measuring equipment has to be
cleaned with different standards (see below).
2. Clean the mounting equipment with a soft, lint-free dust cloth. If necessary, you can
dampen the cloth.
Do not use chemical cleaning agents or solvents like alcohol or cellulose lacquer
thinners.
