The default total gas flow rate for the T700 Dynamic Dilution Calibrator is 2 LPM. The
calibrator uses this flow rate, along with the concentrations programmed into the
calibrator for the component gas cylinders during set up, to compute individual flow
rates for both diluent gas and calibration source gases in order to produce calibration
mixtures that match the desired output concentrations.
This Total Flow rate may be changed to fit the users‟ application. Once the flow is
changed, then the new flow value becomes the total flow for all the gas concentration
generated and computes again the individual flow rates of the component gases and
diluent accordingly.
• The minimum total flow should equal 150% of the flow requirements of all of the
instruments to which the T700 will be supplying calibration gas.
• Example: If the T700 is will be expected to supply calibration gas mixtures
simultaneously to a system in composed of three analyzers each requiring 2
LPM , the proper Total Flow output should be set at:
