  5. Inventory • Customer Service • USA – 866-517-5580 (0830 to 1700 EST) • Technical Service • USA – 800-856-1716

  6. Inventory How many 90-minute batteries come with the VT2? What power options are there for the VT2? What is used to clean components on the VT2?

  7. 9 1 2 MENU TO QUIT - - - ENTER CODE - - - - ENTER - TO ACCEPT Menus Administrator Log-on Administrator PIN 9 1 2 Operator mode 0 0 0

  8. MENU2 CAL ON SUBSTANCE INT l 8 SMP l 0 PLASMAGRAM MENU3 ADJUST WINDOWS CAL FLOW SAVE PKS RAW CONNECT WIRE IR Menus Administrator Menus

  9. Menus What is the Administrator log-on number? What are some features of the Administrator mode? How do you return to Operator mode?

  10. Calibration • Why calibrate? • Calibration introduces a known substance into the detector for identification. • After the VaporTracer2 identifies the calibrant, the software will adjust the positions of all substances. • The VaporTracer2 must be calibrated for accurate detection.

  11. Calibration • When do you calibrate? • After powering up • After changing modes • At the beginning of each shift • When the unit is moved • At higher elevations • When atmospheric conditions change (humidity, pressure)

  12. CAL REQUIRED TNT _ _ NIT _ _ RDX _ _ PET _ _ HMX _ _ AM _ _ MENU TO CONTINUE Press to begin calibration. Calibration

  13. MENU 1 SELECT SUBSTANCE BEEPER OFF LIGHT ON METHOD VAP INT ON OFF PART EXT CAL Use to highlight CAL EXT, then press. Calibration

  14. INSERT CAL TRAP TIME STD LAST 6.169 6.134 -MENU- TO EXIT -START- TO CAL Calibration Insert the calibration trap into the desorber and then press .

  15. STD 6.16 LAST 6.13 HEIGHT TIME -ENTER- TO ACCEPT GET EXPANDED LIST 5892 6.154 Calibration Press to accept the highlighted peak.

  16. If the proper peak is not highlighted, use to select it. The correct peak is the peak closest to the STD peak (usually between 6 and 8 ms). STD 6.16 LAST 6.13 HEIGHT TIME -ENTER- TO ACCEPT GET EXPANDED LIST 6328 6.159 234 3.289 567 9.583 Calibration

  17. CALIBRATION DONE -ENTER- TO CLEAR TO VERIFY THE CALIBRATION INSERT VERIFICATION TRAP THEN PRESS START Calibration • Verification • When Calibration is done, insert a Verification trap (marked with “V”) into the desorber and press START.

  18. VERIFY SUCCESSFUL REMOVE TRAP AND PRESS ENTER TO CLEARDOWN READY P+ 10 100 1k 10k TNT -- NIT -- RDX -- PET -- HMX -- AM -- VERIFY FAILURE REMOVE TRAP AND PRESS ENTER TO CLEARDOWN THEN CALIBRATE AGAIN Calibration Verification Results The READY screen displays after CLEARDOWN.

  19. Calibration Why is calibration necessary? Which menu is used to access calibration? How do you verify calibration? If a calibration peak is not highlighted, which arrow do you use to select the proper peak? When do you calibrate?

  20. Preventive Maintenance • Shift • Weekly • Monthly • Annual

  21. Preventive Maintenance ITMS Detector Schematic

  22. Dopant Dryer Desorber Display Screen Membrane Preventive Maintenance Detector Schematic

  23. Preventive Maintenance Shift Maintenance • Power-down the unit. • Wear white cotton gloves. • Clean the desorber. • Clean the membrane. • Calibrate.

  24. Preventive Maintenance Weekly Maintenance • Power-down the unit. • Wear white cotton gloves. • Change the dryer. • Inspect dryer tube o-rings. • Clean the fan filter. • Inspect the dopant. • Calibrate.

  25. Preventive Maintenance Monthly Maintenance • Power-down the unit. • Wear white cotton gloves. • Perform Weekly Maintenance. • Change the membrane. • Power-on the unit. • After 4 hours, calibrate.

  26. Preventive Maintenance Annual Maintenance - Radiation Wipe Test Wipe around the entire nozzle area. Wipe around the entire seam between the top and bottom housing.

  27. Preventive Maintenance When is preventive maintenance required? How many hours do you wait to calibrate after monthly maintenance is completed? What are the steps for weekly maintenance? Are wearing cotton gloves optional?

  28. Miscellaneous Features Vapor Sampling • A substance must give off a sufficient amount of vapor to be detected. • Heat increases the amount of vapor that is emitted. • The vapor must be contained (vapor release point).

  29. Miscellaneous Features Vapor Calibration and Verification • After attaching the vapor plate, the unit will need 15 minutes to adjust temperatures. • Perform calibration. • MENU 1 Highlight CAL INT. • Verify calibration using the Check Sample.

  30. Miscellaneous Features Changing Modes • Power-down the unit. • Remove the compartment cover. • Plug in and insert the module. • Reinstall cover. • Power-on the unit. • Calibrate.

  31. Miscellaneous Features How is a mode module inserted into the VT2? What is the vapor plate? How do you verify vapor calibration?

  32. Course Review • Inventory • Menus • Calibration • Preventive Maintenance • Miscellaneous Features
