  • Page 24: Calibration

    For two point calibrations it is preferable to use the gas concentrations at the lower and upper end of your measuring range. 6.1.1 Calibration gas purities and flooding time Messkonzept uses gases with the following purities for calibration: File name: FTC300 Manual 1.09KD140704CWI1V05.pdf...

  • Page 25: Set Offset Gas Concentration

    These gas purities are selected such that the devices comply with the specifications for the smallest measuring ranges feasible with the FTC300. Messkonzept recommends gases of same purity for calibration on-site. For differing individual requirements, opt for an appropriate gas purity.

  • Page 26: Offset Calibration

    After quitting the calibration, you are asked to apply process gas again, giving you time to restore your typical process measurement environment while error warnings are deactivated and relays stay frozen (see Section 8.3.5 if you wish to set up relays to be frozen during calibration). File name: FTC300 Manual 1.09KD140704CWI1V05.pdf...

  • Page 27: Gain Calibration

    Instead of using toxic or explosive gases for calibration, substitute gases may be used. A substitute gas has (at a certain concentration) the same thermal conductivity as the test gas it is substituting, such it can also be used for the calibration instead. Please contact Messkonzept for details on possible substitute gases for your application.

    P76 (see Section 8.5.1) sets the number of digits after the decimals point between 1 and 4 when the display unit is set to Vol.%. The resolution in ppm is always 1 ppm. All internal calculations of the FTC300 are done in ppm.Values retrieved through the RS-232 interface will always be in ppm with 1ppm resolution.

  • Page 32: Response Time Setup

    Note that the response time in your process depends greatly on the upstream volume before the FTC300. Shorter and/or thinner tubing will benefit response times. The T90-time is the time, in which a sudden change of the measurand (e.g. the gas concentration) reaches 90% of it’s final value.
