Cleaning
Caution…
Before cleaning the calibrator, you must switch it off, allow
it to cool down and remove all cables.
Caution – Hot surface
•
Over 50°C/122°F
If the calibrator has been heated up to temperatures
above 50°C/122°F, you must wait until the instrument
reaches a temperature below 50°C/122°F before you
switch it off.
Caution – Hot surface – ETC-125 A only
•
Do not remove the insertion tube from the calibrator
before the insertion tube has cooled down to less than
50°C/122°F
•
Never leave hot insertion tubes which have been removed
from
the
calibrator
unsupervised
–
unauthorized
personnel might pick up insertion tubes causing severe
burns.
•
Never place a hot insertion tube in the optional carrying
case.
Below 0°C/32°F
•
Do not touch the well or insertion tube when these are
below 0°C/32°F - they might create frostbite.
•
If the calibrator has reached a temperature below
0°C/32°F, ice crystals may form on the insertion tube and
on the well. This, in turn, may cause the material
surfaces to oxidize.
To prevent this from happening, the insertion tube and
the well must be dried. This is done by heating up the
calibrator to min. 100°C/212°F until all water left has
evaporated.
