Calibration
While the EntryRAE has been factory calibrated prior to shipment, transport
and storage after leaving the factory can affect the sensors. Therefore, any
newly purchased RAE Systems Instrument should be fully calibrated by
exposing it to known concentration calibration gases before the instrument
is put into service for the first time. For safety, check the accuracy of the
monitor by exposing the sensors to calibration gas(es) before each day’s
use. (Refer to “Calibration” on page 10.)
Caution!
Before each day’s usage, sensitivity must be tested on a known
concentration of methane gas equivalent to 20% to 50% of full-scale
concentration. Accuracy must be within 0% to +20% of actual. Accuracy may
be corrected by calibration. Refer to “Calibration” on page 10.)
Long-Term Storage
Reliable performance of this gas detector is based upon regular usage.
For long term storage, the battery should be disconnected. Preparation for
use after long storage requires installation of the batteries and a warm-up
period of at least 10 minutes for the sensors to equilibrate. The user should
recognize that sensor life is based upon the purchase date.
Readings
Any rapid up-scale reading followed by a declining or erratic reading may indicate
a gas concentration beyond the upper scale limit, which may be hazardous.
CAUTION: HIGH OFF-SCALE READINGS MAY INDICATE AN EXPLOSIVE
CONCENTRATION!

been set to run silently; see page 24), the LEDs
blink twice, and the vibration alarm turns on and
off.
2.4 The preset alarm limits appear in order:
HIGH, LOW, TWA, STEL.
3.0 The Time and Date settings are checked:
3.1 The time is shown in 24-hour format, and the
date is shown in “ddmmyy” format.
3.2 If the monitor has never been programmed, you
will see a “date error” message. Press @ to
acknowledge the error. (Refer to “Adjust Date?”
on page 20 to reset the time and date.)
4.0 PID Warm-up:
4.1 If the monitor has not been used recently, PID
warm-up of up to three minutes (180 seconds)
occurs. During this time, the PID lamp icon
appears, as well as a countdown from 180 to 1.
Operating the EntryRAE
5.0 The date of the last calibration is checked:
5.1 Calibration Needed
This message appears if the number of days
since the last calibration is greater than the “Cal
Due Day” setting. (Refer to “Calib Due Day?” in the Calibration section on page 24.)
NOTE: If the Time and Date are invalid or
were recently updated, then calibration is
automatically due. Press @ to acknowledge
the message.
6.0 A Fresh Air Calibration is requested
6.1 Perform a fresh air calibration before each use.
6.2 The monitor must be in clean ambient air during
fresh air calibration.
6.3 Press Y and the calibration begins. The display
counts down from 5 to 0 (6 seconds), at which
time the process is complete.
6.4 “Cal Updating.” The calibration data is updated,
the monitor warm-up is complete, and the
EntryRAE is in Monitor Mode.
Turning the Monitor Off
The monitor cannot be turned off until after the warm-up sequence is
completed.
To turn the monitor off:
1.0 Press the @ button for 5 seconds.
1.1 The display counts down from 3 to 1
(3 seconds), and flashes the LED for each
count.
1.2
Release @ when “Unit Off” appears on the display.
Operating the EntryRAE Monitor Mode
In Monitor Mode, the EntryRAE samples the environment and displays
real-time readings for each enabled sensor.
The Pump Cycle
Under normal operating conditions, when the monitor is not in an alarm
state, the pump cycles on and off about every 8 seconds. This on/off cycle
improves the reliability of the PID and saves battery life.
The pump runs continuously when:
1.0 The concentration of any measured gas or vapor triggers an alarm
condition.
2.0 When the concentration of VOCs is nearing an alarm condition.
Continuous Operation of the Pump
Pressing the Y key and the N key simultaneously causes the pump to run
continuously for 5 minutes. This value can be changed using the ProRAE
Studio software.
Detecting Gases and Vapors Real-time
CAUTION: HIGH OFF-SCALE READINGS MAY INDICATE AN
EXPLOSIVE CONCENTRATION.
ATTENTION: LES LECTURES HORS ÉCHELLE ÉLEVÉES PEUVENT
INDIQUER UNE CONCENTRATION EXPLOSIVE.
Operating the EntryRAE
In Monitor Mode, the EntryRAE samples the environment and displays
the current measured readings for each enabled sensor.
It also calculates and stores the High, Low, STEL and TWA for the
sensors. Press @ to scroll through these readings:
TWA - The Time Weighted Average for CO, H2S, and
VOC gases only; the accumulated reading of the
gas concentration since the monitor was turned on,
divided by 8 hours. Updated every minute.
STEL - The Short Term Exposure Limit for CO, H2S,
and VOC gases only; the average reading of the
gas concentration for the last 15 minutes, which is
updated every minute. Dashes (“- - -”) appear for the
first 15 minutes.
HIGH - The highest reading for each gas
concentration since the monitor was turned on;
updated every second. Press Y to reset the high
values.
LOW – The lowest reading for each gas
concentration since the monitor was turned on;
updated every second. Press Y to reset the
minimum values.
Operating the EntryRAE Calibration
While EntryRAEs are calibrated prior to leaving the factory, temperature
extremes and/or shocks during shipment can cause sensor drift. Therefore,
the accuracy of any newly purchased RAE Systems monitor should be
tested by exposing the sensor(s) to known concentration calibration gas
before the monitor is used or put into service. For maximum safety, the
accuracy of the monitor should be checked by exposing the sensor(s) to
known concentration calibration gas before each day’s use.
Les indications de toute instruments de RAE Systems doit être testé
en exposant l’instrument à une concentration de gaz connue par une
procédure dietalonnage avant metre en service l’instrument pour la
première fois. Pour une sécurité maximale, la sensibilité du EntreRAE doit
être vérifie en exposant l’instrument à une concentration de gaz connue
par une procédure diétalonnage avant chaque utilisation journaliere.
Information regarding sensor expiration is listed in Technical Note TN114, available at www.raesystems.com.
Calibration Equipment
The sensors are calibrated using both fresh air and calibration (span)
gas. The EntryRAE span gas mixtures are fixed. To calibrate an
EntryRAE, the following items are needed:
A. A cylinder of four-gas mix containing:
 50% LEL methane
 20.9% O2
 10 ppm H2S
 50 ppm CO
B. A cylinder of 100 ppm isobutylene.
C. A calibration adapter to connect the monitor to the outlet of the gas
cylinder.
Calibration Procedure
The calibration procedure is broken down into three steps. All steps
should be performed whenever calibration is needed.
Step One: Enter Programming Mode
1.0 The monitor must be in Programming Mode
for calibration.
1.1 Press and hold @ and N for 3 seconds to
enter Programming.
1.2 Password Enabled Monitors.
10 Operating the EntryRAE
1.2.1 If a password is enabled, you are
prompted to enter one.
1.2.2 Use Y to increase the digit and N to
decrease the digit.
1.2.3 Use @ to move to the next digit.
1.2.4 Press @ and Y to enter the password.
1.2.5 If the password is incorrect, the monitor
returns to Monitor mode.
Step Two: Fresh Air Calibration
The monitor must be in clean ambient air during fresh air calibration.
2.1 Press Y and the calibration begins. The display
counts down from 5 to 1 (5 seconds), at which
time the process is complete.
2.2 Calibration Updating
The monitor is in the process of calibrating the
sensors. As it completes, the display shows
the sensors registering zero (or 20.9% for O2),
before it moves to the next step, “Span Cal?”
Using External Zeroing Organic Filters
Use an external zero organic filter (P/N 008-3024-000, 3-pack) if the
ambient air may be contaminated with hydrocarbons. Attach the filter
to the EntryRAE during fresh air calibration. The filter can be used up
to 20 times before disposing. This filter removes most heavier organic
and inorganic compounds, but may not completely remove lighter
compounds such as methane, propane and CO. Note that the filter
should be attached to the EntryRAE before the calibration adapter.
Step Three: Span Gas Calibration for Multiple Sensors
3.0 For this calibration step, the LEL, CO and H2S sensors are calibrated
using the 4-gas mix (P/N 600-0050-004).
Operating the EntryRAE 11
Figure 4. Gas Cylinded with Regulator.
Figure 5. Calibration Adapter.
3.1 Connect the calibration adapter to the EntryRAE and put a regulator
(500 cc per minute flow rate) on the 4-gas mix cylinder.
Figure 6. EntryRAE Connected to Calibration Gas.
3.2 After “Span Cal?” appears on the display with the
CO, H2S, and LEL sensors indicated, press Y.
3.3 Turn the gas all the way on.
3.3 Connect the open end of the calibration
adapter to the regulator. The monitor starts to
countdown from 70 seconds.
3.4 When the countdown timer reaches zero, turn
off the gas, and disconnect the calibration
adapter from the regulator.
3.5 Compare the readings displayed to the span
gas values indicated on the gas cylinder. The
readings should closely agree with the span gas
values.
12 Operating the EntryRAE
3.6 If calibration fails, the monitor briefly displays “Err”
above each failed sensor.
NOTE: Stop calibration in the event that the
gas runs out or is disconnected. To interrupt
calibration, press @ . When calibration stops, the
sensors revert to their previous calibration values.
3.7 After briefly displaying the concentration, the
monitor moves on to calibrating the PID.
Step Four: Span Gas Calibration for the PID Sensor
4.1 The final step is to calibrate the PID sensor.
4.2 Connect the EntryRAE calibration adapter to the monitor (see Figure
6) and put a regulator (500 cc per minute flow rate) on the cylinder of
isobutylene.
4.3 Connect the open end of the calibration adapter to the regulator.
4.4 When “Span Cal?” appears on the display
with the VOC sensor indicated, press
Y and turn the gas all the way on. The
monitor counts down from 30 seconds.
4.5 Turn off the gas, dicsconnect from the
adapter, and remove the calibration
adapter from the monitor.
If the calibration fails, the monitor briefly
displays “Err” above the failed sensor.
NOTE: Stop calibration if the gas runs out
or is disconnected. To interrupt calibration,
press @. When calibration stops, the
sensors revert to their previous calibration
values.
Operating the EntryRAE 13
Optional Step: Zero Calibration for the
Oxygen Sensor
Zero calibration for the oxygen sensor is not required
under normal use. A span calibration using ambient
air (20.9% O2) is usually sufficient to establish its
performance. However, zero calibration may be required
for special applications. Zero gas (100% nitrogen) is
not included in the standard calibration kit and may be
ordered separately (P/N 600-0062-000).
Zeroing the O2 Sensor
 Connect the calibration adapter to the EntryRAE and
put a regulator (500 cc per minute flow rate) on the
cylinder of nitrogen.
 Connect the open end of the calibration adapter to
the regulator.
The display reads “Zero Cal?” and only the O2 segment
appears.
 Press Y and turn on the gas.
If the calibration fails, the monitor briefly displays “Err”
above the failed sensor.
NOTE: Stop calibration in the event that gas runs out
or is disconnected. To interrupt calibration, press @ .
When calibration stops, the sensors will revert back to
their previous calibration values.
Note that each sensor has cross-sensitivities to several gases. These
gases, sensor sensitivity, and other sensor specifications are listed in
Technical Note TN-114, Sensor Specifications And Cross-Sensitivities,
available at www.raesystems.com. Information regarding LEL sensor
poisons is located in Technical Note TN-144, Handling LEL Sensor
Poisons, also available at www.raesystems.com.

mark (“?”) blinks. Press Y to accept the changes. Press N to discard the
changes. Press @ to change the due date.
Calibration Period
The EntryRAE should have a fresh air calibration before each use and
should be fully calibrated:
 no less than every 30 days
 if it does not pass a fresh air reading
 if it does not pass a field calibration.
Operating the EntryRAE 15
EntryRAE Usage Overview
After the EntryRAE is warmed up, calibrated, and charged, it is ready for
use to enhance your personal safety.
CAUTION: HIGH OFF-SCALE READINGS MAY INDICATE AN
EXPLOSIVE CONCENTRATION.
Storage
Always keep the EntryRAE on its charging
cradle in a dry indoor area when it is not in use.
See page c for long-term storage warnings and
procedures.
Confined Space Pre-Entry Test
It is important to always test the atmosphere inside a confined space before
entering. Be aware of any hazardous chemicals you may be bringing into
the space. Remember that many cleaners, paints, adhesives, degreasers
and other modern industrial products (even treated wood) contain volatile
organic compounds that may be hazardous to your health and safety.
Test the atmosphere in the confined space by sampling air at three levels
(top, middle and bottom) in the confined space. Give the instrument time
to sample the gas at each level - the correct sampling time is 60 seconds
plus 1 second for every foot of tubing.
Alarms
If there are any gas ALARMS at any level in the confined space, that
space is not safe. DO NOT ENTER! Identify the alarm condition and then
start your preventive actions according to your company’s confined space
entry procedures.
No Alarms
If there are no alarms, the confined space may be safe to enter. Disconnect
the tubing before carrying the EntryRAE into the confined space. If
monitoring is to be done by a confined space attendant, they should
continue to monitor while you enter the area. If the monitor alarms and
“BAT” is displayed, the battery needs to be charged: There are 15 minutes
16 Operating the EntryRAE
or less of run time remaining. Leave the Confined Space immediately!
(Refer to the Applications and Technical Notes Guide, P/N 000-4001-000,
for more information regarding confined space entry and other applications.)
After Usage
 Press the @ button for 5 seconds.
 The display counts down from 3 to 1
(3 seconds).
 Release @ when “Unit Off” appears on the
display.
 Return the EntryRAE to the dry, indoor storage
area and put it in its charger.
Alarm Signals
When an alarm condition occurs, the monitor provides audible, visible
and vibration alarms to alert users of unsafe conditions.
Auto Reset and Latched Alarm
The EntryRAE comes from the factory with “Auto Reset Alarm” turned
on. This means that the alarms cease when the alarm condition is no
longer present. Alternatively, this feature can be changed and set up as a
“Latched Alarm.” When the alarm system is “Latched,” Y must be pressed
to acknowledge the alarm condition and to reset the alarms.
The Auto Reset function does not automatically reset if a sensor fails
calibration and goes into alarm. The sensor must be successfully
calibrated in order to clear this alarm.
Testing Alarm Signals
Press Y while in monitoring mode. If the alarm is functional, the buzzer
beeps once (if the monitor is not set to run silently; see page 24), the
alarm LED flashes once, and the vibration alarm turns on and off.

Back Light
The back light makes it easy to read the display in poor lighting conditions.
It automatically turns on in low lighting conditions.
NOTE: Heavy back light usage can shorten battery life 20% to 30%.
18 Operating the EntryRAE
Sampling Pump
Under normal operating conditions, when the monitor is not in an alarm
state, the pump cycles on and off about every eight seconds. This on/off
cycle improves the reliability of the PID and saves battery life. Press the Y
key and the N key simultaneously and the pump will run continuously for
five minutes. The pump also runs continuously when:
1.0 The concentration of any measured gas or vapor triggers an alarm
condition.
2.0 The concentration of VOCs approaches alarm conditions.
The monitor can detect any obstructions in the external filter that causes
a pump stall. The alarm activates and the pump symbol blinks in the
upper right corner of the display. Clear the obstruction.
Press Y to start the pump again.
Datalogging
Datalogging occurs automatically for all enabled sensors at one-minute
intervals, allowing five days' continuous data storage. When the end of
the storage memory is reached, the monitor automatically wraps around
to the beginning of the log and overwrites the oldest stored data.
NOTE: Datalogging pauses when the monitor goes into Programming
Mode.
Charging the EntryRAE
The battery charge is indicated on the EntryRAE screen by the battery
charge status icon on the monitor’s LCD. When the icon’s segments are
filled in, the battery is charged. As the battery is discharged, the segments
disappear, indicating that the unit should be charged before use. Refer to
“Maintenance” for instructions on changing/removing the battery.
The Li-Ion battery pack can be charged alone or while it is installed in
the monitor. To charge an installed battery, simply plug the transformer
into the cradle and into an AC electrical outlet. Place the monitor in the
cradle. �����������������������������������������������
The monitor (or battery) is fully charged when:
 The LED on the charging cradle is green
 The “Fully Charged” message appears on the display
 The segments of the battery icon are blinking.
Operating the EntryRAE 19
The monitor (or battery) is still in charging mode when:
 The LED on the charging cradle is red
 The “Monitor Charging” message appears on the display
 The segments of the battery icon are scrolling.
Figure 6. Installing the battery pack into the charging cradle.
To charge the battery pack
alone, place the battery
pack on the charging cradle,
matching the contacts on the
battery pack to the contacts
on the charging cradle.
Figure 7. Contacts on the battery pack.
20 Operating the EntryRAE
The Li-Ion Battery Pack
The factory-supplied Li-ion battery pack is designed to last for 16 hours
of normal operation between charges (without alarm or back light
conditions). The rechargeable batteries have a 1-year warranty. Age,
ambient temperature, and heavy usage may impact battery life.
Battery packs slowly drain even if the monitor is turned off. Therefore,
it is strongly recommended that the EntryRAE be stored on its charging
cradle. The battery can trickle-charge when not in use.
If the battery packs have not been charged for 10 days, the battery
voltage will be low. Fully charge battery packs before going into the field,
and recharge them upon returning from the field.
To reduce the risk of ignition of hazardous atmospheres, recharge
battery only in areas known to be non-hazardous. Remove and replace
battery only in areas known to be non-hazardous.

CO Sensor Charcoal Filter
The carbon monoxide (CO) sensor may be sensitive to hydrocarbons, so
use a charcoal filter (P/N 008-3006-005) to reduce or eliminate organic
vapor contamination or cross-sensitivity. The charcoal filter is installed in
the gas plate above the CO sensor. Under normal operation conditions,
the charcoal filter lasts from four to six weeks before it needs to be
replaced. If the monitor has been exposed to high concentrations of
VOC gases for a prolonged period of time, the carbon filter needs to be
replaced more frequently.
Place the carbon filter above the CO sensor on the gas plate.
NOTE: The CO charcoal filter lowers the reading if it is accidentally used
on other sensors.
