2. ON/OFF Control
When pin 1 on the operating mode selector (SW201) is set to the ON
position, the temperature setting range limit values, hysteresis,
heater current, and heater burnout alarm value can be set or
changed. Any of these parameters can be selected by pressing dis-
play key the required number of times as follows.
Upper-limit value of tem-
perature setting range
Lower-limit value of temper-
ature setting range
