clogged
with ice
Remove the compressed-
air cooling unit, heat the
sample holder inside
TTK 600 to 200 °C for one
hour and blow dry air or
nitrogen through the cryo-
stat.
In case of the LN2 cooling
equipment, remove the LN2
inlet connection from the
Dewar. Close it by the use
of the delivered plug and
wait until all parts reached
room temperature. After
that heat the sample holder
of TTK 600 to 200 °C for
one hour and blow dry air or
nitrogen through the cryo-
stat by removing the plug
and inserting a suitable gas
hose in the inlet connection.
NOTICE
Risk of damage.
The pressure of the drying gas (dry air or nitro-
gen)
must not exceed 0.4 bar
during the drying
of the cryostat.
Higher pressures could damage the heater of
the instrument.
