AC current measurements The Range setting also selects the span of voltages or currents that will be monitored Lastly the Range setting selects the resolution that will be reported by the measure ment The 51 1 Vdc range is particularly useful in monitoring batteries that may exceed 24 Vdc when charging The 255 Vac range is useful for monitoring the AC power source connected to a battery charger The DC and AC current ranges are intended to be used with the CWR CS Current Sensor Each of the Ranges identified as AC utilize a true RMS method of measurement Consequently these settings can also be used when monitoring inputs with variable DC or pulse content Filter The Filter parameter can be set to either Fast or Slow The Fast setting utilizes a time constant of 1 seconds It is generally used when monitoring DC signals The Slow setting utilizes a time constant of 64 seconds It should be used when monitoring AC signals in order to smooth out their ripple content If the user is unconcerned about the Filter time constant it is best to use the Slow default setting Low and High Limits Analog Inputs are constantly compared to two Limit Values The Low and High Limit Values define regions of acceptable and unacceptable operation Outside the acceptable region the input is considered to be in an abnormal state An Event Record will be created when the Analog Input transitions into or out of either region Figure 4 on page 25 illustrates t
