DIGITAL TYPE NUMERICAL VALUE SETTING DEVICE

摘要

PURPOSE:To perform numerical value setting by plural variable resistors easily at high accuracy by making numerical value setting by analog using a variable resistor selected by a selector circuit while watching the content of display of a digital display unit. CONSTITUTION:The selector circuit 10 is driven by a signal from a processing device 20, and selects signals from variable resistors 52-55 when setting constant. Selected signal, for instance a signal e2 from the resistor 52 is A/D converted by an A/D converting circuit 21. This digital signal is converted by a signal converting circuit 22 to signals necessary for digital display, and displayed in the digital display unit 61. Then, an operator moves the brush of the variable resistor 52 to change resistance value and performs setting of constant.
