Panasonic KT4R series offers both economy and high performance. Operation startup can begin after using initial setting mode to enter the control values required before first use, and after entering values for items such as frequently used and frequently changed settings. Smooth operation is enabled at initial startup and after changing settings. Easy programmed control made possible using nine-step setting procedure. By entering specific target values for each indicated period, freely selectable temperature control is possible. Sampling period rate half (1/2 times) from previous model: high speed 125 ms processing implemented. With twice the responsiveness, it is possible to more finely carry out control, for example, of the heat capacity. The built-in rearing auto tuning function uses the step response method. From temperature rise behavior alone, it can calculate the PID constants.
