7.1 Cleaning
Caution…
Before cleaning the calibrator, you must switch it off,
allow it to cool down and remove all cables.
The insertion tube must always be removed from the
calibrator after use.
The humidity in the air may cause corrosion oxidation
on the insertion tube inside the instrument. There is a
risk that the insertion tube may get stuck if this is
allowed to happen.
Caution – Hot surface
Do not remove the insert from the calibrator before the insert
has cooled down to less than 50°C/122°F
Warning (all versions)
Never leave hot insertion tubes that have been removed
from the calibrator unsupervised – they may constitute a
fire hazard or personal injury.
If you intend to store the calibrator in the optional
aluminium carrying case after use, you must ensure that
the instrument has cooled to a temperature below
100°C/212°F before placing it in the carrying case.
Do not touch the well or insertion tube when these are
deep frozen – they might create frostbite.
Users should/must carry out the following cleaning procedures as and
when required:
