WARNING
- Do NOT proceed before reading -
This manual must be carefully read by all individuals who
have or will have the 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.
CAUTION!!
To reduce the risk of electric shock, turn off power before
removing the monitor cover. Disconnect the battery before
removing sensor module for service. Never operate the
monitor while the cover is removed. Remove monitor cover
and sensor module only in an area known to be non-
hazardous.
The model PGM-7600 equipment is classified as to intrinsic
safety for use in class I, division 1, groups A, B, C, D, or
non-hazardous locations only.

Special Notes
-1-
When the MiniRAE 2000 Monitor is taken out from the
transport case and turned on for the first time, there may be
some residual organic or inorganic vapor trapped inside the
detector chamber. The initial PID sensor reading may
indicate a few ppm. Enter an area known to be free of any
organic vapor and turn on the monitor. After running for
several minutes, the residual vapor in the detector chamber
will be cleared and the reading should return to zero.
-2-
The battery of the MiniRAE 2000 monitor will discharge
slowly even if it is turned off. If the monitor has not been
charged for 5-7 days, the battery voltage will be low.
Therefore, it is a good practice to always charge the monitor
before using it. It is also recommended to fully charge the
monitor FOR AT LEAST 10 HOURS before first use. See
Section 7 for more information on battery charging and
replacement.

v
WARNINGS
STATIC HAZARD: Clean only with damp cloth.
For safety reasons this equipment must be operated and
serviced by qualified personnel only. Read and understand
instruction manual completely before operating or
servicing.
Use only RAE Systems battery packs, part nos. 012-3050,
012-3051 or 012-3052. 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.
The calibration of all newly purchased RAE Systems
instruments should be tested by exposing the sensor(s) to
known concentration calibration gas before the instrument
is put into service.
For maximum safety, the accuracy of the MiniRAE 2000
should be checked by exposing it to a known concentration
calibration gas before each day’s use.

AVERTISSEMENTS
DANGER RISQUE D'ORIGINE ELECTROSTATIQUE:
Nettoyer uniquement avec un chiffon humide.
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, la
reference 012-3050, 012-3051 au 012-3052. 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 emplacements
désignés non-dangereuse.
La calibration de toute instruments de RAE Systems
doivent être testé en exposant l’instrument a une
concentration de gaz connue par une procédure
diétalonnage avant de mettre en service l’instrument pour la
première fois.
Pour une securite maximale, la sensibilité du MiniRAE
2000 doit être verifier en exposant l’instrument a une
concentration de gaz connue par une procédure
diétalonnage avant chaque utilisation journalière.

GENERAL INFORMATION

1. GENERAL INFORMATION
MiniRAE 2000 Portable VOC Monitor (Model PGM 7600) is a
compact monitor designed as a broadband VOC gas monitor
and datalogger for work in hazardous environments. It monitors
Volatile Organic Compounds (VOC) using a Photo-Ionization
Detector (PID) with a 9.8 eV, 10.6 eV, or 11.7 eV gas discharge
lamp. Features are:
•Lightweight and Compact
-Compact, light weight (19 oz.) and rugged design
-Built-in sample draw pump
•Dependable and Accurate
- Up to 10 hours of continuous monitoring with
rechargeable battery pack
- Designed to continuously monitor VOC vapor at ppm
levels
•User Friendly
-Preset alarm thresholds for STEL, TWA, low and high
level peak values. Audio buzzer and flashing LED display
are activated when the limits are exceeded.
•Datalogging Capabilities
-15,000 point datalogging storage capacity for data
download to PC
MiniRAE 2000 consists of a PID with associated
microcomputer and electronic circuit. The unit is housed in a
rugged ABS + PC case with a backlit 1 line by 8 character dot
matrix LCD and 3 keys to provide easy user interface.
