1.4 - Initial Usage
Identify if the following parts are present:
•
TA-1200PLAB Calibrator;
•
Metallic or ceramic insert;
•
Bottom insulation of the insert (only one central hole);
•
Top insulation of the insert (same holes of the metallic insert);
In the core of the dry block TA-1200PLAB there is a ceramic tube. Therefore, for
safety purposes, the insert and the insulators are separated. A support is sent to protect
the block. Remove the screws indicated by the arrows and remove the support. Store it
and use it whenever you need to transport the dry block.
Finish the mounting using the grounding pin board and the frame with a grid.
1.4.1 - Mounting the Insert in the Calibrator - Vertical Model
To mount the insert inside the Calibrator, proceed as follows:
I) Place the Calibrator in its definitive place and spacing more than 25 cm from nearby
walls.
II) Observe in the following figure the type of gap in the lower part of the metallic insert
with the type of fitting in the grounding pin inside the furnace well. Note: The ceramic
insert does not have this gap.
I) Screw or fix the extractor to the insert and holding the insert with both hands slowly
insert the heavy insert into the very fragile ceramic well. Orient yourself by the mark
of a point on the insert to keep this side up.
II) It is essential to ensure an effective grounding if the gap coincides with its fitting on
the grounding pin. It is necessary to repeat the movement of the insert back and
forth a few times in the well to hear the click noise between the insert and the
grounding pin. Unscrew the extractor.
III) Then insert the top insulation in line with the holes in the insert. Use a ceramic rod
for it.
IV) Finally, tighten the metal cap by aligning it with the other holes in the top of the
calibrator well.
Note that the sensors to be tested must pass through the insulation and deepen
inside the metal insert to obtain a correct temperature measurement.
