Page 20: Detection Of The Peak Values
6.2. DETECTION OF THE PEAK VALUES The STI-N118 controller is equipped with peaks detection function. It can detect a peaks of the input signal and display their values. Presets connected with this function are placed in “HOLd” menu (see description of “HOLd” menu). The detection of the peak can be done if the measured signal raises and drops of value at least equal to parameter “PEA”. -
