Medi-Gas G210
Introduction
The G210 analyser is specically designed for highly accurate measurement and
verication of the quality of piped N2O and O2gases in hospitals. This instrument enables
up to four gases to be measured, easy user calibration, quick verication of gas quality,
user maintained site and sample point IDs for monitoring as well as identication of
contaminants CO and CO2
The analyser monitors these gases at the following measurements:
●N2O 0 - 100%
●O20 - 100%
●CO 0 - 500 ppm (Optional)
●CO20 - 2000 ppm

1 Please note: Throughout the guide the gas used as an example in the diagrams is O2, the
instructions follow the same procedures for the other three gasses that the G210 monitor
detects.

1 Press the Red power button to turn the unit on and wait 60 seconds for the unit to
warm up. During this time attach the moisture lter and pressure regulator kit.
2 The unit will automatically run a test to identify any problems or indicate if it is due a
calibration. Once this test has run it will sit in a dormant monitoring mode.
3 From this dormant mode you can press Menu and then you have a list of additional
options;
AInformation (Informs you of the Serial number,
Version of rmware, when the service is due and
the unit is ready to come back to ‘Bedfont Scientic
Ltd’ to be serviced, when the unit was last factory
calibrated and when the last user calibration was
conducted.)
BUtilities (Allows the user to change the time and
date, set the contrast if the unit is hard to see, set alarms for the dormant monitoring mode
to alert staff if an area has reached dangerous levels of gas, additional user settings, ow
fail options, logging options for the data collected and a reset tool, which should only be
used when instructed to do so).
CCalibration (This is where the unit is calibrated to avoid the sensor from drifting.
Please nd calibration procedure in the relevant section. Please note; the calibration
procedure states the user should conduct a Zero calibration prior to using the monitor on a
daily basis and the unit should also be calibrated at least once a month with the calibration
gas).
DView Data (This option will give a digital read out of the last data that was logged on
the unit. Data settings can also be accessed through this option. This data is more detailed
through the G210 software kit).
EDiagnostics (This section is only used when diagnosing any faults with the monitor.
Bedfont will ask you to provide information from this section, should you encounter any
problems).

Monitoring Procedure
The G210 monitor should be connected to the gas
outlet safely by using a MED-REG-KIT supplied
by Bedfont Scientic Ltd. At each outlet, allow for
a stable reading. We recommend testing outlets
the same method as calibration, with a Y-piece
connector (ensuring that the gas is vented away
from the user) and testing with the pump activated
when using the MED-REG-KIT.
Peak Reading
The operator can toggle the reading mode
between normal (current) and peak readings.
Whilst in peak reading mode the instrument will
only display peak values for each of the channels.
These values can be stored by pressing the ‘store’
key or automatically at the appropriate logging
interval (if logging is enabled).
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 conrm
the ID choices.
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. To activate, press the soft key ‘Hold’
and the readings are xed until the ‘Hold’ key is
pressed again or until the reading is stored.
Note: Please be careful not to leave the hold button
activated

Flow Fail
A rare occurance with the G210 is when the monitor
displays ‘Flow Fail’, represented by a ashing fan icon.
If, during monitoring the G210 unit displays ‘Flow Fail’
you will need to follow the below steps to diagnose the
problem:
1 Note: Dirty or discoloured lters should be changed before use.
2 From the main screen, press the ‘Menu’ key on the
instrument panel
3 From here press Menu/ 2-Utilities/ 5-Flow Fail
and ensure the monitor states +4 as shown in the
diagram.
4 If the monitor states anything different use the < left and > right cursor keys to adjust
the value displayed. The larger the value, the less sensitive the ow fail detection is.
5 Once this step is complete return to the main screen by pressing Accept/ Exit/ Exit.
6 Please refer to the chart on the next page for more information on the ow fail process

Medi-Gas G210
Calibration
There are two types of calibration that the G210 unit requires; a zero and a span gas
calibration. The ‘zero’ calibration needs to be done prior to use on a daily basis and the
‘span gas’ calibration needs to be done monthly. The example gas in the Span Gas section
of the guide is O2. To complete these types of calibration please follow the below steps:
Zero Calibration: This type of calibration is to be completed with an N2provided by
Bedfont . Connect the cannister as shown in the diagram below.
1 Initiate the calibration by pressing Menu/ 3-Calibration/ 1-Zero with N2.
2 Turn the cannister on, then press the Pump button. Wait approximately 5 minutes and
then press the Start soft key to start the Zero calibration.
3 The monitor will read ‘Waiting for the gas to stabilise’. At this point you must wait
between 60-120 seconds for the gas to stabilise and then the monitor will show
‘Completed OK’.
4 To nish press Accept/ Exit/ Exit to take you back to the original dormant screen. The
monitor should now read 0ppm or 0% to show it has been zeroed.
Span Gas Calibration: This type of calibration is to be completed with the correct
calibration gas canister. The example gas given in this section of the guide is O2, and
must be carried out in the same way with the other three calibration gases. This type of
calibration must be completed on a monthly basis. It is
strongly advised that you only use the gases supplied by
Bedfont Scientic Ltd.
1 Attach the ow regulator onto the top of the canister
of O2safely by holding the regulator in one hand and
twisting the canister with the other away from your
body.
2 Ensure there is gas inside the canister by observing
the needle on the regulator has moved up the scale.
3 Remove connecting tubes attached to the G210
monitor.
4 Connect the G210 unit to the canister of gas with the
tubes provided by referring to the label.

9
Medi-Gas G210
English
5 The tubing should be connected to the canister and then split at the Y piece.
One way will supply the unit and the other way will act as a route for waste gas to
escape without over pressurising the unit.
6 When all the tubes are connected as per the label
diagram (previous page), revert to the unit and
press Menu/ 3-Calibration/ 2-Span Gas/ 1-Span
with O2.
7 At this point the monitor should show ‘1-O299.9%’
(if for any reason the monitor states a different
value of gas press 1-O2/ Input the value of O2
stated on the canister/ press the Enter key).
8 At this point you must turn the gas on by twisting the valve on the side of the regulator
attached to the canister to the ON position and then press the Start soft key.
9 The monitor will now display ‘ow gas now’ and two values, as seen in the image. The
‘Now’ value will be increasing/decreasing and the ‘Ref’ value will state 99.9%.
10 Now leave the monitor until it gives a stable
reading.
11 You will now nd that the ‘Now’ value has
stopped increasing/decreasing and stabilised.
At this point press the ‘Accept’ soft key and the
span gas calibration will now be complete.
12 Exit back to the original dormant screen and you will nd the monitor is still reading
99.9%.
13 At this point twist the valve to ‘OFF’ on the cannister and remove the tubing.
14 This Calibration type is now complete and will not need calibrating again for one
month.
15 Please note: This must be repeated with the other calibration gases supplied using
their retrospective menu selections.
