Abstract

PURPOSE:To automate adjusting work by checking the waveform length, waveform interval, etc., of an output waveform of a control signal received by a control part based upon various existing control signals and reporting the checked results to an A/D conversion data input device. CONSTITUTION:When the check of a measuring processing sequence is started, an arithmetic processing unit (APU) 1 outputs a control signal 13 and an input device 2 outputs the signal 13 to an A/D conversion data output device 3. At the time of receiving the signal 13 by an A/D conversion data control part 6, the output device 3 controls a storage part 9 and outputs existing A/D conversion data 12 to the input device 2. When waveform check for the signal 13 is selected, a control signal inspecting part 8 judges whether the waveform length or waveform interval of the signal 13 is normal or not by checking it and outputs a control signal 14 for reporting the checked result to the APU 1 and an A/D conversion data input device system 10 executes the processing of the inspected result.
