1 Introduction
LANDTEC is the premier manufacturer of products, instruments and software for landfill gas extraction and
for regulatory monitoring compliance. LANDTEC has provided the landfill industry with a technologically
innovative family of products for more than a decade. These products are the result of field-proven
experience in design, operation and maintenance of landfills for environmental compliance.
The GEM2000 and GEM2000 Plus, designed by LANDTEC, are specifically for use on landfills to monitor
landfill gas (LFG) extraction systems, flares and migration control systems. Both instruments sample and
analyze the Methane, Carbon Dioxide and Oxygen content of LFG. The GEM2000 Plus also samples and
analyzes Carbon Monoxide and Hydrogen Sulfide. The readings are displayed and can be stored in the
instrument and downloaded to a personal computer for reporting, analyzing and archiving.
The GEM2000 / GEM2000 Plus instrument is shipped in a protective hard case with a foam interior that
offers additional protection, transportation convenience and component hardware storage. When properly
sealed, the hard case is watertight. The hard case is equipped with a pressure relief valve (located under
the handle on the case) that is normally kept closed. If there is a change in elevation, the hard case may
not open until the pressure relief valve is opened to equalize internal pressure. When shipping a GEM2000
/ GEM2000 Plus back to LANDTEC for calibration or service, always ship it in the hard case to protect unit
from damage.

2 General Operational Features
2.1 Physical Characteristics of the GEM2000 / GEM2000 Plus
2.2 Storage
Do not keep the instrument in the trunk of a car or shed because it may be exposed to temperature
extremes.
When not in use, instruments should be kept in a clean, dry and warm environment such as an office.
The instrument batteries should be discharged and fully charged at least once every four weeks regardless
of indicated charge state. The discharge function may be carried out with the use of the Data Logging
Function in GA mode of operation.

GEM2000 & GEM2000 Plus Operation Manual
Page 3
2.3 Battery/Charging
The Battery Charger IS NOT covered by the unit UL certification. Therefore, when connected to the
Battery Charger, the instrument IS NOT intrinsically safe and should not be used in confined
spaces.
The battery used in the GEM2000 / GEM2000 Plus is a Nickel Metal Hydride manufactured as an
encapsulated pack from six individual cells. This type of battery is not so susceptible to “memory effects” as
Nickel Cadmium batteries, although it is not recommended that the unit be given short-term charges. When
the flashing LED indicates “Trickle Charge” the charging is completed and the unit can be disconnected
from the charger.
The battery charger indicates when the unit is charging, charged or if there is a fault. A full charge should
take approximately 2 hours.
2.4 Instrument Certification
The GEM2000 / GEM2000 Plus is UL/Sira certified for use in hazardous locations. Specifically certified as
to intrinsic safety for use in hazardous locations Class I, Zone 1, AEx ib d IIA T1 (Ta=32°F to +104°F).
For the certification to remain intact it is vital the instructions in this manual are followed closely and repairs
of this equipment be carried out in accordance with the applicable code of practice by an approved repair
facility. See section 9.2 for a list of authorized repair locations.
It is the responsibility of the operator to determine the protection concept and classification required for a
particular application.
2.5 Safety Information
The GEM2000 / GEM2000 Plus is normally used for measuring gases from landfill sites. Inhaling these
gases, or gases from other sites may be harmful to health and in some cases may be fatal. It is the
responsibility of the user to ensure that he/she is adequately trained in the safety aspects of the gases
being used and that appropriate procedures be followed. In particular, where hazardous gases are being
used the gas exhausted from the analyzer must be piped to an area where it is safe to discharge the gas.
Hazardous gas can also be expelled from the instrument when purging with clean air.
2.6 Turning the Instrument On/Off
When switching the instrument on, a long beep will sound, followed by the LANDTEC logo being displayed
and the self-test will commence. Whenever a key is pressed the unit will emit a short ‘beep’ as an
acknowledgement. This function cannot be turned off.
When switching the instrument off, the On/Off button must be held down for approximately 2-3 seconds, at

GEM2000 & GEM2000 Plus Operation Manual
Page 4
which point a clean air purge will be carried out. If for any reason the instrument ‘locks-up’ and will not
switch off, press and hold the On/Off button for 15 seconds. This will force the instrument to switch off.
2.7 Warm-up Self Test
When switched on, the instrument will perform a predetermined self-test sequence taking approximately 30
seconds, during this time many of the instrument’s functions are tested, including:
General operation
Pump function
Gas flow measurement
Calibration
Backlight function
Solenoid function
During the self-test, the following information is also displayed:
Software version
Serial Number. Calibration due date.
Date format.
Operating language.
Communication Baud rate.
2.8 Warning and Error Display
During the self-test, if any operational parameters are out of specification or the pre-programmed
recommended calibration/service date has passed errors or warnings may be displayed. Only three
errors/warnings can be displayed at any time. To ascertain if more errors occurred, use the ‘’ and ‘’ key to
scroll up/down the list, to exit from this screen press the “Enter/Store” key ‘’.
2.8.1 WARNING Displayed
All warnings displayed will be prefixed by the word ‘‘WARNING‘followed by a relevant description. Two
types of warnings may be displayed.
1. General warnings that may not have an effect on the instrument’s function and those where the self-
test has detected a function that is outside the usual programmed operating criteria (e.g. Battery
charge low, memory nearly full, etc.).
2. Specific warnings of operational parameters that can affect the performance of the instrument (e.g.
O2Cell out of calibration, CH4out of calibration, CO2out of calibration, etc.).
The most likely reason for the errors is either an incorrect user calibration, or sensor failure. If an incorrect
user calibration has caused the warning, it should be correctable by way of returning the instrument to
factory settings, zeroing or carrying out a user calibration as necessary for the relevant function.
2.8.2 ERROR Displayed
All errors displayed will be prefixed by the word ‘ERROR‘ followed by a number and description. The errors
detected by the self-test are usually caused by a user calibration being out of specification or possibly
memory corruption. This will have an effect on the functionality of the instrument and should be corrected
before use (e.g. 01 - User cal data, CH4reading or channel out of specification, 02 - User cal data, CO2
reading out of specification).
If any other Warnings or Errors are displayed, contact a LANDTEC Authorized Service Facility for further
information.

GEM2000 & GEM2000 Plus Operation Manual

2.9 Service Information Screen
Upon self-test completion, the GEM2000 / GEM2000 Plus will display service information including when
the next manufacturers service is due, what type of service agreement the instrument is under (if
applicable), and when the last factory gas check was performed. To exit from this screen press the
“Enter/Store” key ‘’.
2.10 Technician ID Screen
The Technician ID screen is displayed after the Service Information screen. While it is not necessary to
input a Technician ID it is possible to select a technician from a predetermined list (created in LSGAMS) or
input up to four characters to identify the technician performing the readings. This ID will be appended to all
readings that are taken until the instrument is turned off. To change the Technician ID simply turn the
instrument off and back on again. The Technician ID can be input through a virtual key board shown on the
instruments display. Letters or numbers can be selected by using the ‘’ and ‘’ key to scroll up/down and
the ‘’ and ‘’ to scroll left and right. Pressing the “Enter/Store” key ‘’ will select the highlighted character.
Once the Technician ID is selected, or to bypass selecting any characters press the ‘’ button.
2.11 Gas Reading Screen
After inputting or bypassing the Technician ID, the instrument will go into the Gas Reading screen, also
considered the normal operation screen. All operations are carried out from this starting point. The
following information is displayed in various boxed sections at this time:
Current programmed time and date
Current selected ID code
Pump status
Pump run time
Three main constituent gases –CH4, CO2, O2(in %)
Two minor gases –CO & H2S and indication of H2 (GEM2000 Plus only)
Balance gas
Last read time/date (if previous data is in memory)
Technician ID
External devices (displays pod type or temperature probe readings when attached)
% LEL CH4(if selected through LSGAM)
Barometric pressure reading.
Current relative pressure reading (GA mode only)
Gas Pod or Temperature Probe reading (if connected)
Battery Charge graph (5 segment, flashes at 20% remaining)
Memory Usage graph (5 segment, flashes at 5% remaining)
Other options:
Menu Allows access to all instrument user functions.
Next ID Allows the next ID to be selected (if IDs are available).
Measure Flow For GEM mode only.
Previous Reading Allows the previous reading of the selected ID to be viewed (if data is available).

backlight button.

GEM2000 & GEM2000 Plus Operation Manual
Page 6
2.12 Optional Gas Pods
Optional Gas Pods are available for use with the GEM2000 / GEM2000 Plus. These pods are available in
seven different gases with eight different PPM ranges. Connection to the instrument is made via the data
port and exhaust port. The detected PPM level is displayed in the upper right area of the gas read screen
and is saved in the same manner as the other gas readings. The Gas Pods are not classified as
intrinsically safe they should not be attached or detached from the instrument in hazardous areas.
Gas Type Range (PPM) Resolution (PPM)
H2S 0-50 0.1
0-200 1.0
0-5000 35
CO 0-1000 1.0
SO20-20 0.1
0-100 1.0
H20-1000 1.0
HCN 0-100 1.0
Gas Pods are intended for use as an inexpensive detection means and not for regulatory reporting
purposes. If the GEM2000, fitted with a Gas Pod, indicates the presence of the selected gas, further testing
should be performed with regulatory approved instrumentation. LANDTEC recommends that field
calibration be performed using the relevant gas and concentration, prior to sampling with a Gas Pod. If
calibrated properly the accuracy of these Gas Pods are typically 5-10% Full Scale.
2.13 Memory
The instrument's memory is volatile. It is maintained by a battery back-up system, which will maintain the
memory while the battery is being changed.
The memory is not to be used as a permanent storage medium and any data should be transferred to a
more permanent storage medium as soon as possible. An Instrument should never be stored for prolonged
periods with valuable data in its memory.
Although unlikely, sudden shocks, high levels of electromagnetic interference or static discharge may cause
memory corruption or loss. If this occurs, the instrument should be Cold Started and the calibration reset to
factory settings before further use. Cold starting will erase all data in the instrument including
resetting the time and date to the default value.
2.13.1 Cold Start
THIS FUNCTION SHOULD BE USED ONLY AS A LAST RESORT.
(For Gas Calibration Error Messages, confirm that Factory Settings and User Calibration are done).
A Cold Start should only be carried out to correct an instrument if no other course of action has proved
successful. This function WILL ERASE the instrument memory entirely. After a cold start is performed the
user will need to reset the instrument to factory settings, perform a field calibration and reset the internal
time/date to the default settings. Please note that the time/date may only be updated through the
communication software. It cannot be updated manually.
To carry out a cold start, turn the instrument on, before the instrument enters into the self-test screen press
and continue to hold the ‘’ key until a pass code entry screen is displayed. At this point the ‘’ key may be
released. Enter the passcode 12345 and press ‘’ to confirm.
After the pass-code entry has been accepted, the instrument serial number will be displayed along with the
hours in use, pump run time and service dates. There are four options from this screen;

GEM2000 & GEM2000 Plus Operation Manual
Page 7
1 - Cold Start
2 - Recover readings
3 - Print readings
0 - Exit
ONLY select option ‘1’ if a Cold Start is to be carried out. Press key ‘1’ to confirm this operation or press
key ‘0’ to continue with normal operation. If you select ‘1’ to confirm the cold start a message will be
displayed confirming the cold start operation and all memory will be cleared. The instrument will continue to
the technician ID screen.
2.13.2 Recover Readings
THIS FUNCTION SHOULD BE USED ONLY AS A LAST RESORT.
Recover readings is a low level memory function that should only be used as a last resort if all your
readings were inadvertently deleted and you know how many readings you had. This function moves the
memory buffer and can cause instrument corruption. Contact LANDTEC before attempting to recover
readings.
2.13.3 Print Readings
This function is best performed using an appropriate RS232 cable (included with new instruments, also
available from LANDTEC) and the LSGAM software. See section 3.12 Downloading Readings for more
detail.
2.14 RF Interference
The gas sensors, especially the Methane sensor, are sensitive to RF interference.
Any device that transmits radio waves can cause your gas readings to fluctuate. Cell phones are the most
common cause of the problem. You should never use your cell phone while you are taking gas readings.
