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

Mini. RAE 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)

Mini. RAE 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)

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

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

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

Start-up: Programmable Zero calibration • • Unit performs Zero calibration after warm-up “apply zero gas…” If in fresh air, the M 3 K can be calibrated, The ppb. RAE 3000 needs Zero grade air, or a Zeroing kit

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 Mini. RAE 3000 and restart – “Lamp” alarm clears and Mini. RAE 3000 is ready for use • If after restart, “Lamp” message remains, the PID needs service

Start-up: Humidity Check • It is important to check if the instrument responds to moisture 1. Cup hand over inlet or breathe into inlet for 10 -20 seconds 2. Do not block flow • If M 2 K reads >2 ppm or ppb. RAE reads >500 ppb, then the sensor needs cleaning

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.

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

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

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

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

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

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

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

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

Alarm signals

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

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

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

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

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

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

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

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

Zero calibration • If in fresh air, the M 3 K can be calibrated, • The ppb. RAE 3000 needs Zero grade air, or a Zeroing kit • Press Y/+ to start calibration

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 100 ppm Isobutylene for the Mini. RAE 3000 or 10 ppm Isobutylene for the ppb. RAE 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.

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

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

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

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

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

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

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 Bias Electrode Sensing Electrode No dirt build-up to foster a decrease in airspace resistance Dirty Sensor Bias Electrode Sensing Electrode Dirt build-up absorbs water and breaks down airspace resistance leading to sensor “leakage” or moisture response
