Caution – Cold surface
Below 0°C/32°F (applies only to the CTC-140 A
models)
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 the well. This, in turn, may cause the material
surfaces to oxidize
To prevent this from happening, simply heat up the
calibrator to 100°C/212°F until all water left has
evaporated.
Remove the insulation plug while heating up.
It is very important that humidity in the well and insertion
tube is removed to prevent corrosion and frost
expansion damages.
Caution…
About the use:
Do not use the instrument if the fan is out of order.
Before cleaning the calibrator, you must switch it off,
allow it to cool down and remove all cables.
About the well, insertion tube and grid plate:
The well and the insertion tube must be clean before
use.
Do not pour any form of liquids into the well. It might
damage the well or cause a hazard.
Scratches and other damage to the insertion tubes
should be avoided by storing the insertion tubes
carefully when not in use.
The insertion tube must never be forced into the well.
The well could be damaged as a result, and the
insertion tube may get stuck.
The insertion tube must always be removed from the
calibrator after use.
