JPH04262267A - Analog signal level measurement equipment of pen type - Google Patents

Abstract

PURPOSE:To realize an analog signal level measurement equipment small, light and easy of operation. CONSTITUTION:An analog signal input from an input element 1 to input the analog signal by contact with a measured part is digitized at the voltage VP-P of a peak value-to-peak value by a voltage measuring element 2 to be displayed in a display element 3. The electric power necessary to several parts is supplied by a power source element 4. All of the input element 1, voltage measuring element 2, display element 3 and power source element 4 are had within a pen type receptacle 6, and further a clip type terminal 5 for ground is installed on the surface of the receptacle 6.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a side view of one embodiment of the present invention. The embodiment shown in FIG. 1 includes an input section 1 disposed at the tip of a pen-shaped container 6 to input an analog signal by contact, and a voltage level of the analog signal disposed inside the container 6 and input to the input section 1. A voltage measuring section 2 that measures voltage, a display section 3 that is disposed inside a container 6 and displays the measurement results of the voltage measuring section 2 in an easy-to-see manner from the outside, and a power supply to the input section 1, voltage measuring section 2, and display section 3. The power source section 4 is arranged in a container 6, and a grounding terminal 5 consists of a clamping terminal on a clip and a lead wire.

FIG. 2 is a block diagram showing the configuration of the embodiment shown in FIG. The operation of this embodiment will be described below with reference to FIG.

[0008] An analog signal inputted through the input section 1 brought into contact with the part to be measured is used in the peak hold section 21 of the voltage measuring section 2 to measure the voltage level VP-P of peak value to peak value. This is the voltage level indicated by the maximum and minimum values of the input. The peak hold section 21 holds this voltage level VP-P and supplies it to the A/D converter 22. The A/D converter 22 has a voltage level VP-P.
is digitally converted and sent to the display section 3. The display section 3 is
Displays the input digital voltage in a predetermined format. The power supply section 4 is a battery-based power supply that supplies the necessary power to each section, and the overall grounding is ensured by connecting the ground terminal 5 to the earth.

[0009]

As described above, the present invention has the advantage of being compact, lightweight, and easy to operate by configuring the analog signal level detector as a pen type.
