  • Page 7 6-2-15 Operating Principle The CAI 700M HFID methane/non-methane hydrocarbon analyzer uses the principle of Flame Ionization Detection (FID) to determine the hydrocarbons within a gaseous sample. For methane analysis, a solenoid valve diverts the sample through a cutter assembly that removes all the hydrocarbons from the sample except methane.
  • Page 8 700M HFID 6-2-15 Flow System Combustion air and fuel used by the instrument are controlled by an Electronic Proportional Control (EPC) valve whose function is to maintain a constant pressure for combustion air at the inlet to a capillary.

Therefore input registers numbered 1-16 are addressed as 0-15.

  • Page 192 700M HFID 6-2-15 Code 16 This function code is used to write a single floating point register to a remote device. The requested written values are specified in the request data field. Data is packed as four bytes per register. The normal response returns the function code, starting address and quantity of registers written.
