The output is accurate LED. The Maximum Response Time can be set shorter than the Minimum to 0.1% of full scale for Operating Modes 2, 3, and 4. Operating Mode 1 is Response Time. In this case, as long as the input signal period is shorter than the accurate to 0.2% of full scale. The green Input LED blinks at the rate of the Maximum Response Time, the unit continues to indicate the input frequency at input frequency. At about 100 Hz, the Input LED will appear to be solid on. At its output. But, if the input period at any time exceeds the Maximum Response very low frequencies, the Input LED blinks slowly and may also appear to be Time, the unit immediately takes the output to the Low Frequency Cut-out solid on. A loss of signal may also cause the Input LED to remain on, depending Value, regardless of the Minimum Response Time setting. on the DIP switch set-up. In this case, the red LED also turns on. The IFMA is calibrated at the factory for all of the selected ranges. However, The Minimum Response Time parameter sets the minimum update time of the the user can adjust the minimum calibration to any value less than the Full Scale output. The actual response time is the Minimum Response Time plus up to one value, and the Full Scale value to any value greater than the minimum value. If full period of the input signal. The IFMA counts the negative edges occurring the minimum and full scale values are brought closer together, the accuracy of the during the update time period, and computes the average frequency value for that unit decreases proportionate to the decreased range of the unit (See Calibration). time. This action filters out any high frequency jitter that may be present in the input signal. The longer the Minimum Response Time, the more filtering occurs. The Maximum Response Time parameter sets the Low Frequency Cut-out response time for the unit. If a new edge is not detected within the time specified by the Maximum Response Time setting, the unit sets the output to the existing Low Frequency Cut-out Value setting depending on the selected range and calibration setting. 2
