Tn-t/Tn-b
The Tn-t/Tn-b option is for
calibration
of the
displayed temperature
of the table top (Tn-t) and the
drawer (Tn-b). If there is an offset between the value on the display and any measurements made
with a high precision external temperature sensor, this can be corrected. The new temperature
reading will be kept as the displayed value with temperature controlling conducted on this basis.
Follow these steps to navigate in the Tn-t/Tn-b option.

Caution: Any change in the factory set calibration should always be based on very certain
temperature measurements. CooperSurgical only recommend the use of a high quality PT-100
sensor that is calibrated with the precision instrument used for measuring according to the
manufacturers specifications. Ensure an optimal contact between the sensor and the place
measured. Use only a sensor type that is correct for the purpose, and which has the correct
size. If in doubt contact your local CooperSurgical distributor.
INT.T
The INT.T (Integral Time) option is for changing the
base value
for the
PID controller
. This should
not be attempted by unauthorised persons. If set at a different level the controlling principle will
be affected.
From the factory it is set to a closely calculated value specific for the model.
tn-t
CAUTION: Do not change the value here. If by mistake any changes are made or
doubts occur if the value are correct please set the REST function in the menu for
the restore of the defaults.
