  1. Using the MiniRAE 3000

  2. MiniRAE 3000 & ppbRAE 3000

  3. Agenda • Self-cleaning • User Interface • Turning on the MiniRAE 3000 • Recommended Daily Start-up procedure • Hygiene mode & displays • Alarm signals • Programming mode • Charging station

  4. MiniRAE 3000: Self-Cleaning Patented RAE Systems Breakthrough! • Lamp runs for 4 hours during charging • Generates small amounts of ozone to scrub sensor and lamp clean • Without probe user will see lamp glow purple during charging • Increases lamp life • Drastically increases PID stability and reduces requirement for cleaning (Refer to TN-165)

  5. MiniRAE 3000: Self-Cleaning duty-cycle Normal operating pump Pump during duty-cycle • Normal operation, pump shows inflow and outflow • Duty-cycle, pump shows inflow and pump stopped • With pump stopped, lamp generates small amounts of ozone which helps to scrub sensor and lamp clean • Pump starts, dirt is removed from lamp • Drastically increases PID stability and reduces requirement for cleaning (Refer to TN-165)

  6. User Interface LEDs and flashlight • User Interface: • Y/+: tests alarms • N/- • MODE (on) • Flashlight on/off key Display MODE key Flashlight on/off key

  7. Control Buttons • Y/+ always controls left-hand response & increases numerical values • N/- controls right-hand response & moves to next digit • MODE controls center & returns to previous menu

  8. Start-up: Turning On • Press and hold • Release Mode key • Self-test • Final display

  9. Start-up: Programmable Zero calibration • Unit performs Zero calibration after warm-up • “apply zero gas…” • If in fresh air, the M3K can be calibrated, • The ppbRAE 3000 needs Zero grade air, or a Zeroing kit

  10. Start-up: Lamp Alarm • “Lamp” alarm may occur on start-up • This indicates that PID lamp has failed to light • Wait 1-2 minutes • If “Lamp” message remains, turn off MiniRAE 3000 and restart • “Lamp” alarm clears and MiniRAE 3000 is ready for use • If after restart, “Lamp” message remains, the PID needs service

  11. Start-up: Humidity Check • It is important to check if the instrument responds to moisture • Cup hand over inlet or breathe into inlet for 10-20 seconds • Do not block flow • If M2K reads >2 ppm or ppbRAE reads >500 ppb, then the sensor needs cleaning

  12. Hygiene/Search Mode Two main operating modes: • Hygiene Mode: The factory default mode. After warm-up the meter samples continuously • Search Mode: After warm-up the pump shuts off and “Ready…” is displayed.

  13. Hygiene Mode/Basic User *Dashed (- - -) line is automatic return

  14. Hygiene Mode/Advanced User *Dashed (- - -) line is automatic return

  15. Hygiene Mode/Advanced User • Change reference gas without entering Programming Mode • Change measurement gas when reference gas is Isobutylene

  16. Hygiene Mode • Reading in ppm • Gas information • Calibration needed • Wireless status • Battery status • Datalog • Pump Status • Press N/- to move to next screen

  17. TWA/STEL/PEAK • TWA reading • STEL reading • Peak reading • Press Y/+ to clear • Press N/- to move to next screen

  18. Date/Time/Temp • Date • Time • Internal temperature • Press N/- to move to next screen

  19. Gas Display • Calibration Gas • Measurement Gas • Correction factor • Press N/- to move to next screen

  20. PC Communication • Enter PC communication and stop sampling • Press Y/+ to enter PC Comm mode • Press Y/+ to exit after communication is complete • Press N/- to move to next screen

  21. Alarm signals

  22. Search Mode • A discrete sampling mode can easily start/stop datalogging for many points • Perfect for drum or headspace sampling • Optional graphic screen

  23. Optional Graphic Screen • Using ProRAE Studio, set display to graphic display Or • Leave display in ppm reading

  24. Search Mode/Basic User *Dashed (- - -) line is automatic return

  25. Search Mode/Advanced User • Change reference gas without entering Programming Mode • Change measurement gas when reference gas is Isobutylene

  26. Programming Mode • Press and Hold N/- and MODE to enter Programming • Input password “0000” • Or Press MODE

  27. Programming Mode • Navigate using interface of “Select,” “Back,” and “Next” • Press “MODE” to exit Programming • Y/+ to increase numerical values or confirm a question • N/- to decrease numerical values or deny a question

  28. Two-Point Calibration *Dashed (- - -) line is automatic return

  29. Zero calibration • Press Y/+ to select Zero Calibration • Press MODE to return to main display • Press N/- to select Span Calibration

  30. Zero calibration • If in fresh air, the M3K can be calibrated, • The ppbRAE 3000 needs Zero grade air, or a Zeroing kit • Press Y/+ to start calibration

  31. Span Calibration • The menu will return to calibration selection with Span Calibration highlighted • Using a Matched-flow regulator, tedlar bag, or 500 cc/min regulator, attach 100ppm Isobutylene for the MiniRAE 3000 or 10ppm Isobutylene for the ppbRAE 3000 • Press Y/+ to enter Span calibration. • Press N/- to skip Span calibration and return to Zero calibration. • Press MODE to exit and return to the top calibration menu.

  32. Span Calibration • Turn on your span calibration gas. • Press Y/+ to initiate calibration. • Press N/- to abort calibration

  33. Span Calibration • Calibration is complete when instrument reads: Span 1 is done! Reading = xxx. ppm • Instrument then returns to Zero Calibration menu • Select MODE to return to regular Operations • Instrument will then update settings

  34. Power Off • Hold for full 3 seconds • Audible alarm will beep and unit will countdown 5 seconds • Release when you see “Unit Off…” • Unit will stay on if you release MODE key before countdown completes

  35. Charging unit • To Charge unit • Push instrument down on charger • Set back of unit against back wall of charger • To remove unit from charger • Push down on instrument • Pull unit towards you

  36. Removing battery • Rubber boot stays on monitor • First push down on tab • Then pull battery from instrument

  37. Charging battery • Use back of charging station to charge battery externally • Push into contacts • Lay battery flat • To remove battery • Push battery towards station • Lift battery off of charging station

  38. Maintenance • Clean PID Lamp & Sensor • When display creeps upwards after good zero • When PID responds to moisture • When movement of PID results in response on display Clean Sensor Dirty Sensor Bias Electrode Bias Electrode Sensing Electrode Sensing Electrode No dirt build-up to foster a decrease in airspace resistance Dirt build-up absorbs water and breaks down airspace resistance leading to sensor “leakage” or moisture response
