ADDITIONAL SAFETY DETAILS - CSA ONLY

CAUTION: Before each days Usage, test on a known concentration of methane,

equivalent to 25 - 50% of full scale concentration. Accuracy must be within
0 to +20% of actual. Accuracy may be corrected by calibration. (Refer to
Chapter 7 : ‘CALIBRATION’).

ATTENTION: Avant chaque utilisation journalière, testez la réaction de l’appareil
en utilisant une concentration connue en méthane, correspondant à 25-50%
de la lecture à fond d’échelle. La précision doit se situer entre 0 et +20% de la
valeur réelle. La précision peut se corriger en étalonnant l’appareil (voir Chapitre
7 : CALIBRATION).

CAUTION: Any rapid up-scale readings followed by a declining or erratic reading
may indicate a gas concentration beyond the upper scale limit, which may be
hazardous.

ATTENTION: Toute lecture dépassant rapidement le maximum de l’échelle et
suivie par une diminution ou une lecture erronée, indique une concentration de
gaz supérieure à la valeur maximale de cette échelle. Cette lecture n’est pas

signicative.

CAUTION: Substitution of components may impair intrinsic safety.
ATTENTION: le remplacement d’un composant peut porter atteinte à la sécurité

intrinsèque du produit.

CAUTION: Do not charge in a hazardous area. Um = 6V.

ATTENTION: Ne pas charger en zone dangereuse. Um = 6V.

NOTE: CSA have only assessed the LEL combustible gas detection portion of

this instrument for performance.

ii

COPYRIGHT

NOTE : CSA a seulement évalué la partie LIE pour la mesure des performances

en détection de gaz inammables.

NOTE: The instrument contains internal checking of sensor sensitivity, which during
calibration will prevent the sensor being calibrated if it has been contaminated
or reached its end of life. In addition to this the Instrument Management System
(IMS) can be used to track the condition of sensors from stored calibration results.

AREAS OF USE

Exposure to certain chemicals can result in a loss of sensitivity of the ammable

sensor. Where such environments are known or suspected it is recommended that
more frequent response checks are carried out. (Refer to Chapter 3: ‘MANUAL
BUMP TEST’). Chemical compounds that can cause loss of sensitivity include
Silicones, Lead, Halogens and Sulphur.

Do not use instrument in potentially hazardous atmospheres containing greater

than 21% Oxygen.

SPECIAL CONDITIONS OF USE

No precautions against electrostatic discharge are necessary for portable
equipment that has an enclosure made of plastic, metal or a combination of the

two, except where a signicant static generating mechanism has been identied.

Activities such as placing the item in a pocket or on a belt, operating a keypad

or cleaning with a damp cloth, do not present a signicant electrostatic risk.
However, where a static-generating mechanism is identied, such as repeated

brushing against clothing, then suitable precautions shall be taken, e.g. the use
of anti-static footwear.

STORAGE, HANDLING AND TRANSIT

The instrument is designed to handle harsh environments. The instrument is
sealed to IP67 and, if not subjected to misuse or malicious damage, will provide
many years of reliable service.

The instrument can contain electrochemical sensors. Under conditions of prolonged

INTRODUCTION

1.1 GENERAL DESCRIPTION

The GMI PS200 series combines quality, ruggedness and
advanced technology in a user friendly, portable gas detector.
It is compact, lightweight, water resistant, extremely robust

and is suitably certied to recognised International Standards.

The PS200 is designed for conned space monitoring, for

example, in sewers, underground piping, or within tanks and
other personal monitoring applications. With audible, visual
and vibrating alarms, it provides early warning of dangerous
gas levels.

The instrument is available as either a pumped or diffusion
model and is powered by an internal Li-ion (lithium ion)
rechargeable battery with an operating time of up to 80 hours
for non-pumped operation (20 hours for pumped operation).
Operating time is sensor dependent. Maximum recharge
time is 4 hours.

Operated via two push buttons, this instrument provides the
user with a simple to use, yet state-of-the-art, gas detector.
(Fig. 1-1).

The PS200 series features high visibility LED’s, a display that
changes colour from green to red when an alarm is present,
a sounder with a 90dB minimum output and a vibrating

alarm. Users can be condent that, should gas levels exceed
congured threshold limits or a sensor / ow / battery fault

exists, a clear and unmistakeable indication is evident.
