iii
COPYRIGHT
WARNING: To reduce the risk of explosion, do not mix old
batteries with used batteries or mix batteries from different
manufacturers.
WARNING: Never attempt to recharge non rechargeable cells.
CAUTION: Not for use in oxygen enriched atmospheres.
CAUTION: Replace instrument batteries only with approved
batteries, as follows:
ATEX APPROVED INSTRUMENTS:
Alkaline (LR20 ‘D’ size): Duracell Procell; Duracell
Industrial; Duracell Plus; Energizer Ultra; Energizer
Industrial.
Rechargeable (LR20 ‘D’ size): Uniross 2600mAh NiMH.
AREAS OF USE
Do not use instrument in potentially hazardous atmospheres
containing greater than 21% Oxygen. The enclosure material
is polypropylene and must not be exposed to environments
which are liable to result in mechanical or thermal degradation
or to damage caused by contact with aggressive substances.
Additional protection may be required in environments where the
instrument enclosure is liable to damage.
STORAGE, HANDLING AND TRANSIT
Rechargeable batteries contain considerable energy and care
should be taken in their handling and disposal. Batteries should be
removed if the instrument is stored for longer than 3 months. The

INTRODUCTION
The GMI - SHIPSURVEYOR instrument is a single
instrument solution for all your safety monitoring and inerting
applications.
This extremely versatile instrument complies with international
marine regulations for Conned Space Monitoring, Inerting,
Pre-entry Testing, Tank Cleaning and many other marine
applications.
Fig. 1-1 Shipsurveyor Instrument
As a minimum, the instrument provides measurement of
Lower Explosive Level (LEL) and Volume ammable gas
for Shipping Industry surveying and leak detection. Other
gas ranges are available, as detailed in Chapter 2 of this
handbook.
The SHIPSURVEYOR has a variety of user congurable
options. This handbook details the default conguration,
with possible options detailed in italic text.

USER HANDBOOK
The instrument is supplied in a sturdy carrying case that is
able to accommodate a selection of accessories.
For a comprehensive list of accessories that are supplied in
the carrying case and additional accessories available, refer
to Chapter 7 ‘ ACCESSORIES’.
The main features of the SHIPSURVEYOR are:
• A gas detection instrument that is simple to
operate with easy maintenance procedures.
• Two button operation allowing the user access to all
features.
• Two operating modes: Confined Space Monitor
(CSM) mode and Combustible Gas Indicator (CGI)
mode.
• LCD with backlighting which displays the current
gas readings together with operational and status
information.
• Clear battery life indication.
• Audible and Visual alarms enabled in CSM mode
only. Alarm levels are pre-set and an optional
periodic confidence signal is emitted. The
audible and visual condence signals will provide
assurance that the instrument is sensing for gas
without the need for the operator to constantly
view the display. The signals, which consist of
an audible ‘beep’ and a visual pulse of the LED
approximately every eight seconds, are active in
CSM mode.
• Manual and automatic datalogging is available in
CSM mode.
Manual datalogging is available in CGI mode.

INTRODUCTION
• Rugged polypropylene case, sealed to IP54 rating
and suitable for outdoor use.
• Directly interfaces with GMI Auto Calibration Unit.
During normal operation, the top and / or bottom line of the
instrument display indicates button press options.
If the option is not highlighted, a single press of the adjacent
button selects that option.
If the option is highlighted, a press and hold of the adjacent
button selects that option.
An audible ‘beep’ will be heard for a single button press,
and two ‘beeps’ will be heard for a press and hold, of either
buttons.

Shipsurveyor 1.
Note: A congurable option allows the instrument to display
this range type as LFL (Lower Flammable Limit).

GENERAL INFORMATION
2.1 Instrument Models / Ranges
There are eight (8) models in the SHIPSURVEYOR range of
instruments. Not all detection ranges may be included in the
version of instrument selected by your company.
The table below illustrates each model and corresponding
gas sensor ranges included:
SENSORS FITTED

USER HANDBOOK
2.2 Details of Operating Ranges
The basic instrument can measure 0-100% LEL and
0-100% VOL GAS.
Other models can measure the following gas types:
• Oxygen (O2)
• Hydrogen Sulphide (H2S)
• Carbon Dioxide (CO2)
• Carbon Monoxide (CO)
2.2.1 LEL, 0 - 100 %
The LEL range indicates the explosivity of the ammable
gas in the sample. This is displayed as a percentage of the
lower explosive limit (LEL) of the gas.
% LEL is displayed clearly in the LCD. From 0 - 100% LEL,
the digital display resolves to 1% LEL.
A congurable option allows the displayed LEL value to
have a resolution of 0.1% LEL from 0 - 9.9%, and 1% LEL
from 10 - 100%.
When the reading reaches 100% LEL, EEE (over-range) is
displayed. The user can, by using the top button, change
range to % Volume Gas in CGI mode only.
An example of a 10% LEL gas detection reading is illustrated
in Fig. 2-2 (example from Shipsurveyor 1 model).
Fig. 2-2 LEL Example (CGI mode)

GENERAL INFORMATION
2.2.2 Volume Gas, 0 - 100 % (CGI mode only)
This range displays the total volume of a ammable gas.
% VOL is displayed clearly in the LCD. The displayed VOL
gas value has a resolution of 0.1% VOL from 0 - 9.9%, and
1% VOL from 10 - 100%.
A congurable option allows the displayed VOL gas value
to have a resolution of 1% VOL from 0 - 100%.
Fig. 2-3 illustrates a typical VOL Gas display (example from
Shipsurveyor 1 model).
Fig. 2-3 Volume Gas Example
2.2.3 Oxygen (O2), 0 - 25 %
This range displays the % of oxygen in the sample.
% O2 is clearly displayed in the LCD. The displayed oxygen
value has a resolution of 0.1% O2 from 0 - 20.9%, and 1%
from 21 - 25%. Fig. 2-4 illustrates a typical display including
Oxygen (example from Shipsurveyor 2 model).

USER HANDBOOK
2.2.4 Hydrogen Sulphide (H2S), 0 - 100 ppm
This range displays the parts per million (ppm) of Hydrogen
Sulphide in the sample.
H2S is clearly displayed in the LCD. The displayed
hydrogen sulphide value has a resolution of 1 ppm.
Fig. 2-5 illustrates a typical display including Hydrogen
Sulphide (example from Shipsurveyor 3 model).
Fig. 2-5 Hydrogen Sulphide Example
2.2.5 Carbon Dioxide (CO2), 0 - 20 %
This range displays the percentage of Carbon Dioxide in
the sample.
CO2 is clearly displayed in the LCD. The displayed carbon
dioxide value has a resolution of 0.1% CO2 from 0 - 5%,
and 0.5% from 5 - 20%. Fig. 2-6 illustrates a typical display
including Carbon Dioxide (example from Shipsurveyor 4
model).
