time interval counter 中文意思是什麼
time interval counter
解釋
時間間隔計數器-
" function, the user can record behavior directly in the field by setting the time interval through the audio alarm function for time sampling of behavioral data. if the behavior is recorded on videotape, this program can also match its timing with the timing recorded on the videotape or the vcr counter, and the user can correct data directly or press a special key to perform editing functions corresponding to the vcr, including pause for timing, different playback speeds, and modifying previous records. users can also continue recording data from previously saved data in the
在記錄數據功能上，可直接在現場記錄，也能夠配合時段采樣的時間間隔使用鬧鈴功能，也可以配合所拍攝錄影帶上的時間（或錄影機上顯示之時間）做同步記錄；修改功能方面，提供直接按鍵修改或按特殊功能鍵以配合錄影機的特殊功能，包括暫停，不同播放速度和連續多次修改記錄；可選擇單鍵即時記錄 -
The measurement of the time interval of ultrasonic send wave and echo used the catch method of 52 series mcu, and avoided the error that the isr save the current value of counter
超聲波發射波和回波的時間間隔的測量利用了52系列單片機的捕獲方式，避免了因為藉助于中斷服務程序來保存計數器的當前值所帶來的誤差。 -
The calibration of a frequency ( time interval or period ) counter will basically include timebase calibration, and frequency ( time interval or period ) measurement accuracy check at 6 different test points. calibration at additional test points can be arranged on demand
