3.0 G200 Range Optional Products and Accessories
3.1 Optional Products
The G200 analyzer range has a number of optional products for purchase which enhance the
usability and enable further analysis of data and reading information.
Note: For further information, please contact Sales at VIASENSOR Toll Free
(855) VIASENSOR, +1 (800) 968-2026 or email Sales@viasensor.com.
3.1.1 Analyzer Data Manager (Optional)
Analyzer Data Manager software application enables the operator to maximize the
operation of the analyzer by providing the ability to:
• Obtain instrument status.
• View the instrument readings and event log data.
• Download and store readings for further analysis.
• Graph downloaded instrument readings.
• View, import and export the instrument configuration.
• Update the instrument’s firmware.
• Copy data from the G200 Client into other packages such as MS Excel.
• Email data directly from the application.
• Configure remote access to a central database.
• Print graph and tabular data.
3.1.1.1 Event Log
The G200 range of instruments incorporates the facility to log significant events via the
‘Event Log’. This can be used as an aid to monitoring the use of the instrument. It can
also be used as a diagnostic tool if there is a problem with the instrument.
The event log can only be viewed via the optional Analyzer Data Manager software. It
cannot be viewed on the analyzer screen. Applicable events are stored in the event log
automatically. No user intervention is required.
The event log can hold approximately 270 events. If the log becomes full then it begins
to overwrite the older events. This can be identified by the index field which starts from
event number 1. The log is cleared when the instrument is reset.
Note: Please refer to section ‘12.0 Event Log’ of this operating manual for further
information.
3.1.2 Carbon Monoxide Reading (Optional - G210 ONLY)
The G210 instrument has the optional facility to use an internal CO cell (specified at the
time of manufacture). This allows the instrument to read and display carbon monoxide
readings along with N2O.
3.1.3 Oxygen Reading (Optional – G210 ONLY)
The G210 instrument has the optional facility to use an internal oxygen cell (specified at
the time of manufacture). This allows the instrument to read and display oxygen readings
along with N2O, CO2, CO.
3.1.4 Pressure Regulator Kit (G210 ONLY)
A pressure regulator kit must be used when taking gas readings to restrict the flow into
the instrument when using the G210 analyzer. When sampling piped medical gases the
pressure of the gas needs to be reduced before it is passed to the instrument. This
OMG200N1.23 G200 Analyzer Range
VIASENSOR Page 10
reduces the pressure to 40.15” W.C. suitable for the instrument. It is recommended that
the operator uses the pressure regulator kit supplied by VIASENSOR.
Warning
Do NOT use the instrument at full piped pressure (maximum
pressure 120.44” W.C.).
3.1.5 Soda Lime CO2 Filter
This filter is designed to remove ambient CO2 (up to 1500ppm) from the sample gas. For
the G100 range of instruments, it should only be fitted when user zeroing the CO2
Channel in air, thus emulating an equivalent zero in N2. Using the filter is highly
recommended when N2 gas is unavailable and performs a much better zero than selecting
zero with air which assumes 400ppm is present. The actual concentration of CO2 in the air
can vary greatly depending on the environment and can lead to incorrect user calibration.
This filter should always be fitted when using a G200 instrument as any CO2 will crosscontaminate the N2O reading.
The life of the filter will vary depending on usage. The crystals change color from white to
violet. The filter element should be discarded when a significant percentage of the crystals
start to turn a violet color – see below:
Assemble Filter and Connect to Instrument as Shown
New Filter (White)
Used Filter (Violet)
The filters are supplied in a sealed storage bag to
improve their shelf life. The parts supplied should be
assembled as per the diagram shown. Please note the
sample filter is still in place.

should be transferred to a more permanent storage medium as soon as possible. The
instrument should not be stored for prolonged periods with valuable data in its memory.
5.7 Storage
When not in use the instrument should be kept in a clean, dry and warm environment, such
as an office. It should be stored flat with the stand folded away which helps prolong the life
of the O2 cell.
Note: Fully charge the instrument before use if instrument has been stored for six
months or more.
5.8 Warning and Error Codes
When switched on the instrument will perform a predetermined self-test sequence taking
approximately ten seconds. During this time many of the instrument’s working parameters
and settings are checked. If any operational parameters are out of specification or if the
pre-programmed recommended calibration/service date has passed, errors or warnings
may be displayed.
Note: For further information please refer to section ‘8.0 Problem Solving’.
5.9 Battery/Charging
The battery used in the instrument is a 2 Ah Lithium-Ion cell. The instrument must be

5.10 Instrument Main Read Screen
After the analyzer has been switched on and the warm-up self-tests completed
(Approximately 45 minutes) the analyzer will display the following screen.
Main Read Screen
Soft-Keys:
Peak - Enables the operator to display the peak reading.
Store - Enables the operator to store the reading for viewing/download later.
Hold - Enables the operator to hold the current reading being taken.
5.10.1 Alternative Reading Methods
The G210 has three reading types or methods which each require slightly different
operating procedures:
• Peak reading
• Store reading
• Hold reading
Peak Reading:
The operator can toggle the reading mode between normal (current) and peak readings.
While in peak reading mode the instrument will only display peak values for each of the
channels. These values can then be stored by pressing the ‘Store’ key or automatically at
the appropriate logging interval (if logging is enabled).
The peak value is reset after a reading is stored or by exiting the peak mode using the
appropriate soft-key. The current mode of operation can be identified by the status of the
soft-key, either ‘Normal’ or ‘Inverse’, where inverse indicates peak mode is active.
Store Reading:
The ‘Store’ reading option allows the operator to store the current reading. Upon selecting
this option the operator is then prompted to enter or select a ‘Site ID’ and ‘Sample Point
ID’ to identify the reading. Select the ‘Accept’ button to confirm the ID choices. For
further information please refer to section ‘5.11 Enter ID Codes’.
Hold Reading:
The ‘Hold’ reading option allows the operator to freeze the currently displayed reading.
This allows it to be manually recorded or moved away from the sample point. Once
