29. s that fall outside that band are shown as real and not filtered readings The band is configurable between 0 01 and 1 00 of the full scale range of the input channel It can also be set to OFF which means that no filtering is performed i e every reading is a real one and can also be set to ON which means that filtering 15 always shown no matter how big of an excursion Occurs 165 072011 THCD 100 Power Supply Page 9 of 28 b Filter Size The size of the filter is currently configurable between 0 and 6 seconds and simply indicates the amount of readings that are taken and buffered to calculate and show the averaged reading A filter size of 0 will naturally turn off the filtering irrespective of the band setting It should be noted that this type of adaptive filtering can cause readings to be displayed abnormally particularly if the buffer size is one of the larger available settings where the displayed readings seem to jump about as the filter is disabled and then re enabled when the data excursions fall into the preset band This is because outside of the band the display will show the real unfiltered readings whilst constantly taking an average in the background When the excursions fall into the band then the display will switch to showing the filtered data If this data is quite significantly slugged due to a large buffer size then the display will appear to nearly reach the new data value due to real value
30. setpoint control that can be used to operate a mass flow controller or similar The setpoint command output always has a voltage full scale of 5V Example If the input channel is setup for a 100 slpm 5V full scale device and the setpoint value is 10 0 165 072011 THCD 100 Power Supply Page 8 of 28 assuming setpoint is in AUTO mode and not a slave source then the output voltage of the setpoint would be 0 5V The setpoint does have some configuration parameters that can be used to alter the function of the setpoint control and they are detailed as follows a Setpoint Mode The setpoint can be configured in one of three modes AUTO OPEN and CLOSED In AUTO mode the setpoint output is dependant on the setpoint source and value settings see below In OPEN mode the setpoint outputs a voltage greater than the full scale of the device Given that the setpoint command full scale is 5V the output in this mode is 7V In CLOSED mode the setpoint outputs a voltage less than the minimum output voltage of most devices the setpoint output voltage is 0 25 b Setpoint Source The setpoint source dictates where the setpoint value comes from assuming the mode is set to AUTO see above This can be one of two possibilities Internal or Slave Internal source the setpoint uses the value set internally via the 4 amp Y switches or via external communications e Slave source in this case the setpoint uses a perc
