* READ BEFORE OPERATING *
The instrument manual must be carefully read by all individuals
who have responsibility for using, maintaining, or servicing this
product. The product will perform as designed only if it is used,
maintained, and serviced in accordance with the
manufacturer's instructions.
THIS IS A SHORT FORM OF THE MANUAL – THE
COMPLETE MANUAL WITH ALL OPERATION AND
MAINTENANCE INSTRUCTIONS IS CONTAINED ON THE
CD-ROM SHIPPED WITH THIS PRODUCT
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.
ATTENTION!
For European Applications

DEMKO 02 ATEX 04201X
EEx ia d IIC T4 (with Battery Pack P/N 015-3052)
EEx ia d IIC T3 (with Battery Pack P/N 015-3053)
B. Recharge batteries only in non-hazardous locations
C. Do not connect external cable to serial interface jack in
hazardous locations.
D. Use RAE Systems Adapter P/N 500-0072 for connection to
communication port and charging jack only in a non-hazardous
area.
SPECIAL NOTE
When the QRAE Plus multi-gas monitor is taken out of the transport case
and is turned on for the first time, there may be some residual vapors
trapped inside the monitor and the initial toxic gas sensors 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.
WARNINGS!
For safety reasons this equipment must be operated and serviced by
qualified personnel only. Read and understand the instruction manual
completely before operating or servicing.
Use only RAE Systems battery packs, part number 015-305, 015-
3052, or 015-3053. *Battery pack 015-3051 is not approved for use in
Europe. 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
batteries only in non-hazardous locations.
Do not connect external cable to serial interface jack in hazardous
locations.
STATIC HAZARD
Clean only with a damp cloth.
CALIBRATION
The calibration of all newly purchased RAE Systems Instruments
should be tested 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 QRAE Plus by exposing the
sensors to known concentration calibration gas before each day’s use.
READINGS
Anyrapidup-scalereading followedby adeclining orerratic readingmay indicate
a gas concentrationbeyond upper scale limit,which maybe hazardous.
AVERTISSEMENTS!
Pour des raisons de sécurité, cet équipment doit être utilisé,
entretenu et réparé uniquement par un personnel qualifié. Étudier le
manuel d’instructions en entier avant d’utiliser, d’entretenir ou de
réparer l’équipement.
Utiliser seulement l'ensemble de batterie RAE Systems avec numéro
de série 015-3051, 015-3052, our 015-3053. *Le batterie avec
numéro de série 015-3051 est intérdit pour usage en Europe. Cet
instrument n’a pas été essayé dans une atmosphère de gaz/air
explosive ayant une concentration d’oxygène plus élevée que 21%.
La substitution de composants peut compromettre la sécurité
intrinsique. Ne charger les batteries que dans l’emplacements
désignés non-dangereux.
Connectex pas le cable externe au port parallel dans un environment
non-dangereux.
DANGER RISQUE D'ORIGINE ELECTROSTATIQUE
Nettoyer uniquement avec un chiffon humide.
LA CALIBRATION
La calibration de toute instruments de RAE Systems doivent être
testé en exposant l’instrument a une concentration de gaz connue
par une procédure dietalonnage avant de mettre en service
l’instrument pour la première fois.
Pour une securite maximale, la sensibilité du QRAE Plus doit être
verifier en exposant l’instrument a une concentration de gaz connue
par une procédure dietalonnage avant chaque utilisation journalière.
LES LECTURES
Toute lecture rapide et positive, suivie d’une baisse subite au
erratique de la valeur, peut indiquer une concentration de gaz hors
gamme de détection qui peut être dangereuse.

2.2. Operation of Monitor
The functions of the three keys are summarized below.
Table 3. Key Functions
[MODE] Hold for 1 second and release to turn ON; hold for
5 seconds to turn OFF; toggle to different displays.
Exit program menu tier; exit data entry mode when
held for 1 second
[N/-] Answer “No” to a question; decrease a number;
toggle the backlight on & off.
[Y/+] Answer “Yes” to a question; increase a number;
test alarm; alarm condition acknowledgment
The Q-RAE Plus monitor has two operation modes:
1. Basic mode is the simplest mode of operation. The monitor
alternately displays the instantaneous concentration readings
and the sensor names after the monitor is turned on. The user
can press the [MODE] key to see critical data, battery voltage or
enter the PC communication mode. The displays in the main
loop of the Basic mode are shown in Figure 3.

2. Advanced mode, shown schematically in Figure 4, displays
more information than the Basic mode and allows access to
more programming functions. The Programming Mode is
explained in detail in Chapter 4 of the long form manual.
* Datalog appears only when unit has datalogging option and is
programmed in manual datalog mode. LEL gas appears only when
LEL sensor is installed. ** Print Reading appears only if this option is
enabled through ProRAE Suite software.
Figure 4. Displays in Advanced Mode
To choose a specific display, press [MODE] one or more times
until the desired display appears. An “OK!” mark means the
unit is in Basic mode and no alarm condition exists. A small “L”
means the unit is logging data. Press [Y/+] to perform the
function of any question displayed.

pressing [Y/+] momentarily.
WARNING!
The alarm signals are disabled during PC communication,
calibration, and datalog review or when printing to a serial printer.
To reduce the risk of exposure to hazardous atmospheres,
perform these operations only in areas known to be safe. During
these operations, real time monitoring of the gas stops.
