-READ BEFORE OPERATING -
This manual must be carefully read by all individuals who have
or will have the responsibility of 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.
CAUTION!
To reduce the risk of electric shock, turn off power
before removing the housing top or the sensor cover.
Disconnect the battery before removing sensor
modules for service. Never operate this monitor while
the top or the cover is removed. Remove the top, the
cover or sensor modules only in an area known to be
non-hazardous.
SPECIAL NOTE
When the PGM-2000 or PGM-2020 multi-gas monitor is taken
out from the transport case and is turned on for the first time,
there may be some residual vapor trapped inside the detector
chamber. The initial toxic sensor readings may indicate a few
ppm. Make sure the area is free of toxic vapors before turning
the monitor on. After running the monitor for several minutes,
the residual vapor in the detector chamber should clear and
readings should return to 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 015-3051, 015-
3052, or 015-3053. *Battery pack 015-3051 is approved for use in USA
only. 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
Any rapid up-scale reading followed by a declining or erratic reading
may indicate a gas concentration beyond upper scale limit, which may
be hazardous.

AVERTISSEMENT!
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 permit pour I’usage seulement aux Etats-Unis.
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.

GENERAL INFORMATION

1. General Information
The QRAE Plus is a programmable multi-gas monitor designed
to provide continuous exposure monitoring of toxic gases,
oxygen and combustible gases for workers in hazardous
environments.
There are two models available: the PGM-2000, a pump unit,
and the PGM-2020, a diffusion unit. The figures and displays in
this manual are primarily for the PGM-2000 model.
The QRAE Plus monitors inorganic toxic gases and oxygen
concentrations with electrochemical sensors. It monitors
combustible gases with a combination catalytic bead and
thermal conductivity sensor.
The QRAE Plus includes:
•Calibration Adapter
•Quick Reference Guide
•Operation and Maintenance Manual
•Training Video
•Rubber Boot with Belt Clip
