Display method for multiple path ultrasonic flaw detector

Number of alarm indicator lamp equal to number of channel is setup on display screen. Each alarm indicator lamp is to a corresponding channel. Characters are that there is at least one base line on display screen to show waveform of combining detected results from two channels. Concretely, in each stated time interval, using same frequency samples detected results from two channels so as to obtain two pieces of array; then two pieces of array combined into a new array; the new array is sent to display, and one base line shows the result. Advantages are: display screen can display detected results from more channels, suitable higher requirement of increasing distinguishable channels, not increasing working strength of defect detecting operator.
