Page 20: Detection Of The Peak Values
6.2. DETECTION OF THE PEAK VALUES The STI-94 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”.
Page 21: Control Of The Relay Outputs
User manual - RATEMETER STI-94 6.3. CONTROL OF THE RELAY OUTPUTS The control of the object (measured signal) is realized via relay outputs. Front panel LEDs named „ R ” indicates the state of particular relay output. If device is not equipped with one or more relay outputs, menus refer to this relays are available, but apply to LED indicators only.
