1.4
Visually inspect the door and furnace insulation. Verify that no parts are
threatening to fall or are presenting severe cracks that could impair
functionality.
1.5
The “pillar”-shaped insulation part that protrudes from the furnace door
is particularly vulnerable to mechanical stresses. Please make sure not to
break them as you perform the following steps.
1.6
Using dust mask, gloves and vacuum cleaner, remove all dust from
furnace and door. Pay attention not to directly touch the material with
the vacuum tube (the material is very fragile and brittle).
1.7
All parts that are found faulty should be ordered and replaced as fast as
possible.
Thermocouple
junction
IMPORTANT
: Always disconnect the instrument from the power outlet when
working with panels removed. 240 Volts inside! Risk of electrocution!
To run this inspection, instrument must be turned OFF, unplugged and furnace at
room temperature.
Thermocouple used in instrument is made of platinum-platinum/rhodium (type R)
and is normally very durable. In particular, it is impervious to oxidation or damage
by heat; only a mechanical incident could damage the junction (i.e. the tip) of the
thermocouple.
1.
This inspection consists in verifying the junction of thermocouple for visible
damage.
1.1
Unplug the X-300 and let it cool down completely.
1.2
Remove the instrument’s main cover (see page 62,
removal for details).
1.3
The furnace door should be hanging ajar, so that you can see the
thermocouple through the vertical slot opening in the center furnace
section. (The thermocouple looks like a thin white ceramic rod coming
down at a 45° angle. The actual “thermocouple” is the metal junction at
its very tip. A small flashlight may come in handy.)
1.4
Visually inspect the thermocouple junction. Verify that no mechanical
shock has occurred, which could have crushed or otherwise damaged
the thermocouple junction. If junction is damaged, a new thermocouple
should be ordered and installed.

IMPORTANT
: Always disconnect the instrument from the power outlet when
working with panels removed. 240 Volts inside! Risk of electrocution!
To perform functionality verification, do the following:
1.
Power ON the X-300 and select a method that does not heat (e.g. “TEST”).
