G-Finder Multi is a personal safety device
designed to detect the presence of Oxygen (O
2
),
Carbon Monoxide (CO), Hydrogen Sulfide (H
2
S),
combustible gases (default target combustible gas
is methane, CH
4
). Power is provided by one, non-
user replaceable, lithium-thionyl chloride primary
2-cell. The unit includes LCD display to show
readings, as well as audible, visual, and vibrating
alarms are supported when user-configurable
values are exceeded. It is your responsibility to
respond appropriately to the alarms. G-Finder
Multi has no facilities for connection of external
electrical circuits. G-Finder Multi has IR
communications for changing the alarm set point,
calibration range and etc. The IR communications
shall only be used in safe area.
WARNING
1)
G-Finder Multi is designed for single use. Non-
field replaceable lithium-ion battery, filter and
sensor are already installed and ready for use.
2)
Do not attempt replacement or substitution of
components. Replacement or Substitution of
components may IMPAIR Intrinsic Safety and
will void the warranty of the product.
3)
The electrical, electronic and battery elements
of this product must not be disposed of via
municipal waste streams; they should be
disposed of by a qualified recycler or
hazardous materials handler. Correct disposal
will contribute to recycling of materials and
prevent negative consequences for the
environment.
4)
It is recommended performing a bump test
prior to use G-Finder Multi every day to
confirm sensor response and alarm activation
by exposing the detector to a concentration of
target gas that exceeds the low alarm set
point.
5)
For optimal performance, please proceed zero
calibration periodically.
6)
G-Finder Multi is provided with anti-static
coating over the LCD window to minimize risk
of ignition due to electro-static discharge.
Periodic inspection of this coating is required
to ensuring prevention of degradation,
delamination, abrasions or other deformities
to the surface. Please make sure to clean only
with a damp cloth.
7)
For all gas types of G-Finder Multi, always
proceed bump test and calibration at room
temperature and in a fresh air environment
(20.9% v/v O
2
) that is free of hazardous gas.
CAUTION
1)
Activate G-Finder Multi before the activation
date on the package.
2)
In order to maintain normal operation of G-
Finder Multi, keep the gas sensor grill from
clogging and keep the gas sensor, LED and
buzzer hole surfaces free from dust and dirt.
Clean the exterior with a soft and damp cloth.
3)
When using G-Finder Multi, sudden change in
the temperature may cause change in the
detected gas concentration value suddenly.
Using in a stable temperature environment is
recommended for more accurate detection.
4)
The combustible gas sensor is initially
calibrated to 50%LEL methane. Only methane
gas should be used to calibrate or bump test
the combustible gas sensor.
5)
G-Finder Multi is a gas detector, not a
measurement device.
6)
Portable safety gas detectors are life safety
devices. Accuracy of ambient gas reading is
dependent upon factors such as accuracy of
the calibration gas standard used for
calibration and frequency of calibration.
