When remounting the spill tray the
screws have to be cross tightened
with a force of approximately 1N/m.
For best result, tighten the screws
when the calibrator is heated to
80°C. This will soften the rubber
seal, making the junction vertically
waterproof.
After tightening the screws, replace
the silicone seal between the
handle and the spill tray. Put a thin
line of silicone between the spill
tray and the handle and smooth it
out with a wet finger. A god tip is to
recalibrate the instrument, before
the silicone is applied.
B. Removal of Display and Keyboard Unit, all Models
(Exploded views, pos. 2).
Remove the grid plate by
unscrewing the 3 screws (all
models except ATC-140/250 A/B).
Remove the protection shield if
present (only in the early models of
ATC-320/650 A/B).
