The TUNE option is for
calibration
of the
displayed temperature
.
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 control
conducted on this basis.
Follow these steps to navigate in the TUNE option.

Note: Any change in the factory set calibration should always be based on very certain
temperature measurements. CooperSurgical only recommends the use of a high quality
PT-100 sensor that is calibrated with the precision instrument used for measuring according to
the manufacturers specifications. Also ensure an optimal contact between the sensor and the
place measured. Use only a sensor type that is correct for the purpose and of correct size. If in
doubt contact your local CooperSurgical distributor.
INT.T
Should only be performed by an authorized K-System engineer. The INT.T (Integral Time) option
is for changing the
base value
for the
PID controller
. 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.

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.
