Description

[Brief explanation of drawings]

Fig. 1 is a processing flowchart of a voltage recording device according to an embodiment of this invention, Fig. 2 is a H/W configuration diagram of a general voltage recording device, and Fig. 3 is a processing flowchart of a conventional voltage recording device. be. 1 and 2 are processes for selecting the operation mode of the voltage recording device, 3 is a setting of the number of recording start timings until the start of recording, and 4, 5, 6, and 7 are loops until the number of recording start timings set in 3 is reached. Processes 8, 9, and 10 convert the voltage input from the input terminal 100 into digital values and record them in a voltage value recording memory circuit, 101 is a timing signal detection circuit, and 102 is an A/D conversion process. circuit, 103 is a memory circuit for recording voltage values, 104 is a CPU, 105
106 is a storage device for control programs, and 106 is a microcomputer. In addition, in the figures, the same reference numerals indicate the same or corresponding parts.
