Abstract
PURPOSE: To display alarm setpoints for upper limit and lower limit simultaneously by driving desired segment electrodes by transferring upper and lower limit values to a driving part through a changeover means.
CONSTITUTION: When a display changeover switch 2 is opened, a contact 1 (1) is closed and contact 1 (2) is opened. Therefore, only the measured input is sent to an A/D converter 7 and then to a converter 9. Suppose the measured input is 2 in the analog quantity, the output from the converter 9 is finally fed into an exclusive OR gate group 13 to light up segment electrodes S1 and S2, while electrodes S3 to S10 remain unlit. In this state, a display is made. When the display changeover switch 2 is closed, the contact 1 (1) is opened and the contact 1 (2) is closed. As a result, the upper limit value and the lower limit value set at a volume control 4 for setting the alarm points will be sent to the A/D converter 7 alternately according to outputs H, L from an oscillator 6, so that the upper value and the lower value of the segment electrodes in the display part may be display alternately
