Title:
MULTI-CHANNEL GRAPHIC DISPLAYING APPARATUS
Document Type and Number:
Japanese Patent JP3373629
Kind Code:
B2
Abstract:
PURPOSE: To display the relationship of measured data of multiple channels on a graph based on a time and to reduce the power consumption.
CONSTITUTION: This apparatus comprises a measuring circuit having an A/D converter 13 that converts detected signals transmitted from at least two sensors 10 attached on optional different positions into digital data and a memory 16 storing the measured data, a timer circuit 17 measuring time, a graphic display 21 that carries out the graphic display of a relationship of time-measured value during at least 24 hours and a CPU 14 that sequentially reads the measurement signal of the measuring circuit corresponding to the output of the timer circuit 17 to display the temperature of each measuring point as the graphic data on the graphic display 21. The measurement is conducted for every prescribed time period and the power source of the apparatus except the timer circuit 17 is switched off when the measurement is not conducted.
