4.0 After use
Warning
Never leave hot insertion tubes which have been removed
from the calibrator unsupervised – they may constitute a fire
hazard.
If you intend to store the calibrator in the optional 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.
Caution…
•
The insertion tube must always be removed from the
calibrator after use.
The humidity in the air may cause verdigris to form on
the insertion tube inside the instrument. There is a risk
that the insertion tube may become stuck if this is
allowed to happen.
Caution – Hot surface
•
Do not touch the grid plate, the well or the insertion
tube - they may be very hot.
The following routine must be observed before the insertion tube is
removed and the instrument turned off (cf. Fig. 1):
1.
If the calibrator has been heated up to temperatures above
100°C/212°F, you must wait until the instrument reaches a
temperature
below 100°C/212°F before you switch it off.
2. If the calibrator has reached a temperature below 0°C/32°F,
it should be heated momentarily to a temperature of
50°C/122°F.
3. Turn off the calibrator using the power control switch (pos.
7).
4. Remove the insertion tube from the calibrator using the tool
supplied with the instrument.
5.
Optional: Store the calibrator in the carrying case.
