  • Page 204 You will be asked to confirm which instrument channels will use GAS 1 for the calibration. The gas concentration shown next to each channel is the auto calibration value for that channel. If it does not match the gas concentration in the cylinder(s), change the auto calibration value for that channel.
  • Page 205 If you are calibrating a 0 - 10000 ppm range Gas Tracer, the Gas Cylinder Confirmation Screen will appear as shown below. Even though there are no other sensors installed in the instrument, GAS 2 will still be used to calibrate the ppm sensor.
  • Page 206 This is not user adjustable using the PC Controller Program. If the SDM-2012 is not in a fresh air environment, a zero air cylinder must be used with a 6 inch humidifier tube connecting the cylinder to the AIR fitting.
  • Page 207 If you are calibrating any instruments that include a %volume sensor, the screen will appear as shown below and will indicate a gas cylinder change is needed. The ppm sensor will be calibrated first with GAS 2. The standard 3 sensors will then be calibrated using GAS 1.
  • Page 208 If you are calibrating a 0 - 10000 ppm Gas Tracer, the screen will appear as shown below. The ppm sensor will be calibrated using GAS 2. The GAS 2 selection box is deselected by default. You must select the GAS 2 box to bump test the ppm combustible sensor.
  • Page 209 14. 11. Remove any connected cylinder from the GAS 2 fitting and click the Purge button. The SDM-2012 will purge for 30 seconds. 12. At the end of the purge cycle, you will be prompted to reconnect the calibration cylinder to the GAS 2 fitting.
  • Page 210 14. The pumps will start and the program will indicate that air is flowing. The AIR indicator on the program screen will be on. The CAL LED on the SDM-2012 control panel will begin to flash amber. Air will be applied to the ppm sensor for 45 seconds, then the PC Controller Program will perform a zero adjustment on the ppm sensor.
  • Page 211 15. After air is applied, and if the ppm sensor passed the zero adjustment, calibration gas from the GAS 2 cylinder will be applied to the ppm sensor. The GAS 2 indicator on the program screen will come on and calibration gas will be applied to the ppm sensor for 90 seconds.
  • Page 212 16. After calibration gas has been applied to the ppm sensor, fresh air will be applied to the standard sensors (catalytic LEL, O S (GX-2012 only) and CO) and the %volume sensor (if installed) for 45 seconds and the PC Controller program will perform a zero adjustment.
  • Page 213 17. After air is applied, and if all standard channels and the %volume channel (if installed) passed the zero adjustment, calibration gas from the GAS 1 cylinder will be applied. The GAS 1 indicator on the program screen will come on. GAS 1 calibration gas will be applied to the instrument(s) for 90 seconds.
  • Page 214 20. When you have changed the GAS 2 cylinder, click OK. The calibration will continue and the second GAS 2 calibration gas will be applied to the %volume sensor for 90 seconds. Figure 167: %Volume GAS 2 Flowing 209 • Calibrating GX-2012s and Gas Tracers...
  • Page 215 21. The PC Controller Program will analyze the results. 22. After calibration gas is applied, the docking stations will purge with fresh air for 45 seconds. Figure 168: Fresh Air Purge Calibrating GX-2012s and Gas Tracers • 210...
  • Page 216 23. After the fresh air purge is complete, • If the calibration passes, the following window will open indicating that. The LED on the SDM-2012 control panel will be solid green. Click OK to return to the main program window. The CAL LED will turn off.
  • Page 217 Click OK to return to the main program window or double click the instrument information line to view the calibration results in the Logs window. The CAL LED on the SDM-2012 control panel will turn off. Figure 170: Calibration Failed...
  • Page 218 Logs window. The CAL LED on the SDM-2012 control panel will turn off. Confirm all tubing connections are correct and that all lines are clear. Figure 171: Low Flow Calibration Failure 24.
