Read Before Operating
This manual must be carefully read by all individuals who have
or will have the responsibility of using, maintaining, or servicing
it is used, maintained, and serviced in accordance with the
manufacturer’s instructions.
Caution!
To reduce the risk of electric shock, turn off power before removing the
monitor cover. Disconnect the battery before removing sensor modules for
service. Never operate this monitor while the cover is removed. Remove
monitor cover and sensor modules only in an area known to be non-
hazardous.
Special Note
When the EntryRAE monitor is removed from the transport case and is
turned on for the first time, there may be residual vapors trapped inside the
monitor, and the initial toxic gas sensors values may indicate a few ppm.
After running the monitor for several minutes in clean air, the residual vapors
should clear and readings should return to near zero.
Attention! For European Applications
A. Recharge batteries in non-hazardous locations.
B . Do not connect external cable to serial interface jack in hazardous locations.
C. Use RAE Systems Charging cradle (P/N 046-3059-000) for connection to
communication port and charging jack only in a non hazardous area.
Note
Only the combustible gas detection portion of this instrument has been
assessed for performance in accordance with C22.2 No.152-M1984.
Seulement la partie combustible de détection de gaz de cet instrument a été
evaluée pour l’exécution selon C22.2 No. 152-M1984.

Warnings
For safety reasons, this equipment must be operated and
serviced by qualified personnel only. Read and understand the
user manual completely before operating or servicing.
Battery Pack
Use only RAE Systems battery packs (P/N 046-3007-000 or 046-3051-000). This
instrument has not been tested in an explosive gas/air atmosphere having an
oxygen concentration greater than 21%. Substitution of components may impair
intrinsic safety. Recharge/replace batteries only in non-hazardous atmospheres.
Computer Interface
Do not transfer data by means of the computer interface cable in hazardous
atmospheres.
Static Hazard
Clean only with a damp cloth.
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!

Pour une sécurité maximale, la sensibilité du EntryRAE doit être vérifié en
exposant l’instrument. (Référez la Calibration à la page 10.)
Attention!
Avant chaque utilisation journalière verifier la sensibilité avec une concentration
connue de methane equivalante a 20% à 50% de la pleine échelle. La precision
doit être comprise entre 0% à +20% de la valeur vraie et peut être corrigée par
une procédure diétalonnage. (Référez la Calibration à la page 10.)
Stockage à Long Term
Le fonctionnement durable de ce détecteur de gas est conditionné par une
utilisation régulière de celui ci. Lors d’un stockage à long terme, la batterie
doit être déconnectée. Le rédémarrage aprés une longue période d’arrêt,
nécessite la réinstallation de la batterie, et une période de chauffage de 10 mn
afin que les capteurs se mettent à l’équilibre. L’utilisateur doit être conscient
que la durée de vie indiquée pour le capteur démarre à sa date d’achat.

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

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 O
2
),
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 H
2
S sensors are calibrated
using the 4-gas mix (P/N 600-0050-004).
Step Two: Fresh Air Calibration
The monitor must be in clean ambient air during fresh air calibration.

Operating the EntryRAE
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.
3.2 After “Span Cal?” appears on the display with the
CO, H
2
S, 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.

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.
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.
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
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% O
2
) 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 O
2
Sensor
s
Connect the calibration adapter to the EntryRAE and
put a regulator (500 cc per minute flow rate) on the
cylinder of nitrogen.
s
Connect the open end of the calibration adapter to
the regulator.
The display reads “Zero Cal?” and only the O
2
segment
appears.
s
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.
