Do not use this function in the CL model.
Recalibration operation is executed by service personnel.
1-point calibration or 2-point calibration can be performed at any temperature. If the
oven is always to be used at the same temperature, 1-point calibration at that
temperature is sufficient. If the oven is to be used at a wide range of temperatures,
2-point calibration is recommended.
The first calibration temperature must be no greater than 60 °C and the second
calibration temperature must be at least 20 °C higher than the first calibration
temperature. Before shipment, the CTO-40C CL is calibrated at 40 °C and 80 °C
respectively.

Gas Sensor Calibration
Re-calibration is required if the result of [GAS SENSOR CHECK] fails the component
validation.

This function is not used in the CL model.
Recalibration operation is executed by service personnel.
The gas sensor detects volatile gas generated from leaked organic solvents when
the tubing such as a column causes a leakage.
When the output value from the sensor exceeds the level set at "threshold
value", an error occurs and temperature control stops.
The gas sensor is influenced by the concentration of organic solvent gas around
the instrument.
4.4 Leak Sensor Calibration
Re-calibration is required if the result of [LEAK SENSOR CHECK] fails the component
validation.
