Never place a hot insertion tube in the optional carrying
case.
Caution – Hot surface
This symbol is engraved in the well of the ETC-400 A and
in the grid plate of the ETC-125 A / 400 R.
•
Do not touch the well, the insertion tube or the grid
plate, as the calibrator is heating up / has been heated
up – they may be very hot and cause burns.
•
Do not touch the tip of the sensor when it is removed
from the insertion tube/well – it may be very hot and
cause burns.
•
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.
•
Do not remove the insert from the calibrator before the
insert has cooled down to less than 50°C/122°F.
Caution – Cold surface
Below 0°C/32°F (applies only to the ETC-125 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.
It is very important that humidity in the well and insertion
tube is removed to prevent corrosion and frost
expansion damages.
