Other Functions 

Use calibration offset function 

Calibration offset is a function which corrects the difference between the temperature in furnace and 

that of controller (sensor temperature) if arises. The function parallel corrects the difference either to 

the plus or minus side within the whole temperature range of unit. The function can be set or 

cancelled by the SUBMENU key. 

 

 Start operation with the target setting temperature. Check the 

temperature in furnace (temperature of sample) with a thermograph 

after it is stabilized. 

 Check the difference between the setting temperature and that in 

furnace (temperature of sample).

key. This completes the setting. 

 The setting range of offset correction temperature is +99 to plus 

side and -99 to minus side respectively. 

When it is set to the minus side, the temperature on the measurement 

temperature display screen falls by the setting temperature, while the 

temperature on furnace rises. 

When it is set to the minus side, the temperature on the measurement 

temperature display screen rises by the setting temperature, while the 

temperature on furnace falls. 

 The unit has two-point correction function, which performs offset 

between low-temperature zone and high-temperature zone. Please 

consult our local branch office when carrying out validation of 

temperature controller.
