  • Page 42: Calibration

    The F-940 allows the user flexibility with calibrating, there are two methods for calibrating: utilizing the computer-free calibration method through on-device adjustments under Setup > Calibration on the F-940, OR by using the computer software program: G.A.S. (Gas Analysis Software). The G.A.S. Calibration menu also enables a two-point calibration process for the F-940 Store It! Including Zero Calibration and Span Calibration.
  • Page 43 F-940 Instruction Manual rev. 3-8-2017 Set zero should take place weekly for all sensors to maintain maximum performance. The set zero process does not require G.A.S. and can be done following the processes outlined in the “Setup > Set Zero” section of the user manual. Set zero optionally CAN be done with G.A.S.
  • Page 44 If you have already completed the set zero process, press "Ok". Another prompt will appear asking the user to put the device in Continuous Monitor mode (On the F-940 Store It!: Setup > Mode > Measure > Continuous). Then navigate to the main menu and begin measuring.
  • Page 45 F-940 Instruction Manual rev. 3-8-2017 Press "Ok". The G.A.S. software will begin the calibration process and count down. Once the calibration is completed, a green verification can be seen above the start button. Following step 6 of the instructions listed, you should now verify the calibration was successful by taking a reading of the standard gas used in the process.
  • Page 46 F-940 Instruction Manual rev. 3-8-2017 It is highly recommended that this step be performed after one full day has passed since the calibration was performed. If this step is not performed, accuracy of the calibration cannot be verified. Connect and read each gas and record the results here after three minutes (at least) of measure time.

  • Page 47: Applications

    By creating a closed loop, the rigid jar will not pressurize by the displaced sample gas removed from the jar. The gas will be drawn into the F-940, analyzed by the sensor, and then re-circulated back into the jar through the closed-loop sample probe.
