Agenda
• User Interface
• Turning on the UltraRAE 3000
• Recommended daily start-up procedure
• Hygiene mode & displays
• Alarm signals
• Programming mode
• Charging station
User Interface
• User Interface:
– [Y/+] tests alarms
– [N/-]
– [MODE] (on)
– 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 [MODE]
• When display appears,
release [MODE] key
• Instrument performs self-
test
• Final display shows and
unit is ready for zero
calibration
Start-up: Programmable Zero Calibration
• Unit performs Zero calibration after warm-up
• “apply zero gas…”
• If in fresh air, the UltraRAE can be calibrated, or
a Zeroing kit with charcoal tube can be used
Test Pump
• To ensure that there are no leaks,
periodically test the seals.
• With the UltraRAE 3000 running, place
your finger over the end of the inlet probe.
• The alarm should sound and the pump-
stall icon should flash on the display.
• This indicates that all seals are good. Stop
the alarm by pressing [Y/+].
Test Pump
• If the pump does not alarm or show the
stalled-pump icon, then check that all inlet
parts are tight and inspect the O-ring for
damage (replace it if necessary).
• After inspection and/or replacing, test
again.
• If there is still no alarm, send instrument in
for pump service.
Start-up: Programmable Zero calibration
Start-up: Lamp Alarm
• “Lamp” alarm may occur on start-up
• This indicates that PID lamp has failed to light

• If “Lamp” message remains, turn off UltraRAE 3000 and restart
– “Lamp” alarm clears and UltraRAE 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 UltraRAE reads >2 ppm,
then the sensor needs
cleaning
Compound Specific vs VOC Monitor
Two main operating modes:
• Compound Specific Monitor: The
factory default mode. After warm-up, the
meter takes timed samples for Benzene or
Butadiene
• VOC Monitor: After warm-up, the meter
works similar to the MiniRAE 3000
– In this mode, the monitor does not need a
tube, but make sure cap is air-tight.
Compound Specific Monitor
• Turn unit on and wait for warm-up to finish.
• Press [N/-] to advance.
• Before you start sampling, you must insert a
RAE-Sep separation tube into the inlet/holder.
Separation Tube Preparation
• Open a package of RAE-Sep separation tubes
and remove one.
• Place the tip in the package’s tube tip breaker
(the small hole on the front) and snap off the
tip.
Separation Tube Preparation
• Turn the tube around and snap off the other end.
• Handle tubes with care. Tube ends are sharp after
ends are broken off.
Inserting Separation Tube
• Unscrew the front of
the sampling probe
from the base.
• Slip the tube into the
rubber holder in the
front portion.
Inserting Separation Tube
• Insert the other end
of the tube into the
middle of the base
while turning the
front portion to
tighten it onto the
base’s threads.
• Do not overtighten
any portion of the
sampling assembly.
Measuring Compound Specific
• Once the tube is in place, begin measuring
by pressing [Y/+].
• The display shows a countdown
– 60 seconds is standard, but sampling time
depends on the type of separation tube
selected and the temperature.
• You can abort the sampling by pressing
[N/-] at any time.
Measuring Compound Specific
• Once the countdown is complete, the gas
reading is shown.
• Press [Y/+] to continue sampling with the tube
for 15 minutes to establish a STEL reading, or
press [N/-] to return to the main menu
