48 calibration offset function outline of function in the controller, the relationship between the temperature t detected by the sensor and the display temperature of the operation panel d is expressed by the equation of the line which passes the two points (t 0 , d 0 ) and (t s , d s ) shown in fig. 1. here, t 0 is the sensor detecting temperature when the chamber central temperature becomes the zero adjusting temperature (normally room temperature is adopted) d 0 at the time of no load, t s is the sensor detecting temperature when the chamber central temperature becomes the span adjustment temperature (normally working maximum temperature is adopted) d s at the time of no load in the same way. as it is clear from the facts above, conforming of the chamber central temperature and the display temperature is guaranteed only when there is no load and at two points shown above. in other words, it is possible for a temperature measured at a point in the chamber does not conform to the display temperature of the operation panel at a voluntary temperature without load. this is the function to move the line which passes abo ve two points to the y axis direction in parallel (increase or decrease y intercept of the line). the parallel movement amount including a sign is defined as the calibration offset. this function can conform the display temperature of the operation panel to the measurement temperature of a voluntary point in the chamber at a voluntary temperature. in fig. 2, d sv is a display temperature of the operation panel under the condition that the temperature in the chamber is constant for a set temperature. it is natural to say that this value is equal to the target set temperature. d pv is a measurement temperature of a voluntary point in the chamber under this condition. the difference between d pv and d sv including the sign is defined as the calibration offset. therefore offset is shown as below. in fig. 2, d cal becomes the negative value since the target set temperature d sv is larger than the actually measured temperature d pv . in order to conform the display temperature to the actually measured temperature, let the controller to recognize that the temperature in the chamber differs from the target set temperature by d cal . note: setting tolerance of calibration offset ? the calibration offset can be set within 5% of the maximum working temperature of the oven. d s sensor detection temperature display temperature (controlled temperature) t 0 t s d 0 y=ax+b fig. 1 d sv d pv t i t v parallel movement d cal display temperature (controlled temperature) sensor detection temperature fig. 2 d cal d pv d sv equation 1
