What is the difference between measurement cycle and interval ?
* Measurement cycle refers to the time interval used to measure the instantaneous real time value of one cycle of input voltage. * Interval means the time interval for saving and output the measurement data. * The r.m.s. value of voltage, current and electric power value in every one cycle are measured as an instantaneous value. * Calculate the maximum, minimum and average values of instantaneous value being measured within the interval time and save them in the PC card in every interval time. * Instantaneous value (for one cycle) of adjacent interval time is saved in the PC card in every interval time.
