Titration times differ
widely.
• Grind sample before weighing and spread over
sample boat as evenly as possible.
• Position the Oven at a location where it is protected
against draughts and direct sunlight.
The titrator does not
switch off.
• Grind sample before weighing and spread over
sample boat as evenly as possible.
• The sample decomposes and evolves oxidizable
substances: Lower temperature, possibly use N2 as
carrier gas.
Gas does not reach
titration vessel.
• Tube blocked by molecular sieve?
• Inlet of a drying flask blocked by molecular sieve?
• Switch valve to "TRANSFER" and possibly increase
gas flow.
• Are the cover of the insert tube and the sample inlet
at the top closed properly?
• Are all tubing connections tight?
No gas flow although the
pump is adjusted or
another gas is
connected.
• Tube blocked by molecular sieve?
• Inlet of a drying flask blocked by molecular sieve?
• Firmly tighten all tubing connections.
• Has the tubing been connected at the rear of the
oven?
Error message
"conditioning not ok"
although the attached
titrator is conditioned.
• Is the connecting cable to the titrator plugged in

On interconnection with Titrinos, check that the
cable ends have not been mixed up!
