Temperature regulation cannot
reach a stable condition.
The temperature of the cooling
water is outside the permissible
range (12°C to 28°C).
Check cooling water temperature
and correct if necessary.
Check the flow quantity and correct it
if necessary (see Section 11.3).

The calorimeter is incorrectly
detecting a filled inner vessel.
The system displays the mal-
function and interrupts the
measurement.
If there are any drops of water on the
water sensor, remove them (see
Section 11.6).
If the water level in the inner vessel
is higher than 3 cm, empty the inner
vessel.
If this does not resolve the problem,
please contact the Technical Service
Department.
