GS6500 and GS6600: After flashing the model number, the oxygen display (right-hand display on the
GS6600) will flash “hEAt” (Heat) as illustrated below. Since the analyzer cannot produce meaningful
readings until the sensor is at the proper operating temperature, the display will continue to flash
“hEAt” (Heat) until the correct operating temperature is reached (usually about five minutes). In
critical, high-accuracy applications, or when measuring at very low concentrations of oxygen, it is
advisable to wait at least thirty minutes before taking a measurement. This will allow the analyzer to
reach optimal operating conditions.
GS6600 Shown
GS6700: After flashing the model number, the display will show “0.0”. Since the detector will drift
slightly until fully warm, it is suggested that the analyzer be allowed to warm up for thirty minutes before
critical measurements are made.
3.3 Navigating the Menus
The analyzer is configured using the keypad shown above.
The ‘Menu’button allows you to change the menu listing, the ‘Digit Select’button is used to choose
which digit of the display will be changing. The ‘Digit Increment’button allows for digit change, and the
‘Enter’button will store a new configuration in memory.

Changing the program codes to configure parameters is simple. There are three pages of information.
Page 0 contains all the parameters that a test operator may want to use frequently such as changing
Product Code.
Page 1 contains all test configuration parameters which can be (optionally) password protected. The
factory default is password protection disabled. The default password is 1234.
Page 2 parameters are those which are used to configure instrument options that do not need to
accessed frequently. Page 2 parameters are always password protected. The factory default password
is 1234.
To access the parameters in Page 0 press the ‘Menu’ button:
The LED above it will light and the display will
briefly read “Prod” then indicate the current Product
Code. Press the ‘Menu’ button to cycle through
options until the display will read “PA9E” (Page)
briefly then display “0” to indicate you are on Page
0. Available parameters depend on the instrument
model and its configuration.
Every time the ‘Menu’ button is pressed a new parameter will be displayed briefly followed by the value
for that parameter. Note: some parameters are read only.
Continual pressing of the ‘Menu’ button when on Page 0 will eventually show “– O2 –” (for GS6600
and GS6500) or “CO2”(for GS6700) and this signals the end of the Programming mode and the
instrument is returned to the measurement mode (shown below is GS6500 display).
To access the parameters in Page 1 or 2, follow the steps below:
Press the ‘Menu’ button 3
times
The display will briefly read “PA9E” (Page) then
“0” (to indicate you are on page 0).
Now press ‘Digit Select’button
The display will flash.
Now press the ‘Digit
Increment’ button
The display will change from “0”to “1”.

menu 2 if required
The display will change from “1”to “2”.
Now press the ‘Enter’button
The display will briefly read “PAS?” (Password) if
menu 2 was selected (optionally on menu 1) and
then 4 digits. To access the page you must enter a
correct password. At this point the display will read
“0000” and the left-hand “0” will flash, prompting
you to enter the password. The factory set
password is 1234. Enter this password using the
‘Digit Increment’ and ‘Digit Select’ buttons. Press
the ‘Enter’ button. The display will show “yES”
(YES), for a correct password or “nO” (NO) if
incorrect. If you have the correct password, access
is allowed to the page parameters.
Note: to get out of Page 1 or 2 back to Page 0 and return to the measurement mode (“O2” screen for
GS6500 and GS6600 or “CO2” screen for GS6700), you must keep pressing the ‘Menu’ key until you
get to the “PA9E” (Page) parameter, then change the code to “0” using the method shown above (no

NOTE: Alarms triggered on the display will also be shown triggered on the printout if the optional
printer is connected.
5.4 Setting the Test Method
There are several ways the analyzer can be used to measure residual gas in the headspace of MAP
packaged products.
The available test methods are: TIMED
PEAK/VALLEY
AUTOSENSE/CONTINUOUS
5.4.1 Timed
With the timed test method, the test time duration is user-selectable. When the test is started by
pressing the green ‘TEST’ button, the test will run for a fixed period. The reading is displayed during
the test and then remains frozen, so the values can be recorded. The internal sampling pump will stop
at the end of the test time duration. The test time duration can be defined by the user in the Page 1
menu.
Test time duration calculation:
The GS6000 analyzers have an approximate flow rate of 60cc/min (1cc/second). Estimate the
available headspace volume in cubic centimeters in the package or container to be tested. This number
is the approximate maximum test time duration in seconds. For example, if there is 30cc available
headspace in the package or container, the maximum test time duration is 30 seconds. It is important
not to exceed the maximum calculated test time to avoid the following:
1. Drawing product (particulates, liquids, etc.) into the sampling system.
2. Creating a vacuum within the package or container causing ambient air ingress.
3. Deadheading the pump (blocking the flow).
By default, the test time is set for 20 seconds. Use the menu system (refer to section 3.3) to get to
the “teSt” (Test) parameters on Page 1 as shown below:
Using the ‘Digit Select’ and ‘Digit Increment’ buttons, set a new test time in seconds. Press the ‘Enter’
button to save.
5.4.2 Peak/Valley
In the Peak/Valley test method, the final test result represents a peak or valley reading detected during
the test time.
In the Peak/Valley set up page, the test parameters for O2and CO2can be set. The Peak/Valley is
referenced to a normal air measurement, namely 20.9% for O2and 0.0% for CO2. If the package gas
is normally lower than 20.9% O2and higher than 0.0% CO2, then the test should be set up for ‘valley’
on O2and ‘peak’ on CO2. It should be set up on Page 1in “nodE” (mode) menu.

Gaspace 6000 Operations Manual v1.4
www.systechillinois.com
Page
16
By default, the Peak/Valley method is turned off. To change test method to Peak/Valley using menu
system, (refer to section 3.3) get to the “nodE” (mode) options on Page 0 as shown below.
Using the “Digit Select” and “Digit Increment” buttons, set mode to desired peak / valley setup (refer
to menu tables in section 3.3.1 for setup explanations). Press the ‘Enter’ button to save.
5.4.3 Autosense/Continuous
The Autosense test method may be used when measuring many packages. Autosense avoids having
to press the ‘TEST’ button to initiate each test.
Autosense is a user-programmable parameter which specifies the delay time between each test in
seconds. When Autosense mode is selected for the analyzer and the green ‘TEST’ button is pressed,
the first package is tested as described for a timed test. The next test starts after the delay time specified
in “Auto” setup on Page 1. Upon completion of the first test the user has the specified delay time to
withdraw the needle from the first package, prepare and insert the needle into the next package, and
so on until all the packages have been measured.
To pause Autosense, press the green ‘TEST’button or the ‘Enter’ button after the pump stops (before
next test starts). Press the green ‘TEST’ button again to re-start Autosense. To completely stop
Autosense, change “Auto” in Page 1 back to “0”.
To change Autosense to Continuous mode, change “Auto” in Page 1 to “1”. This will cause the pump
to run continuously until the green ‘TEST’button is pressed to stop/start measurements or Autosense
is turned off as described above.
By default, Autosense is turned off. To change Test method to Autosense, using menu system (refer
to section 3.3) get to the “Auto” options on Page 1 of menus as shown below:
Using the ‘Digit Select’ and ‘Digit Increment’ buttons, change “Auto” from “0” to the desired time in
seconds between consecutive tests. Press the ‘Enter’ button to save. To turn Autosense method off
change “Auto” time back to “0”.

5.5 Taking a Measurement
Connect the sampling probe (Wand) to the blue Luer connector on the right side of the instrument and
screw hand tight. Connect the disposable filter and a needle to the sampling probe (Wand).
To take a measurement, follow the steps below:
1. Ensure the GS6000 is operational and ready to use, that it has a clean filter, a needle in good
condition and sampling probe (wand) with no leaks.
2. Situate the package to be measured in such a way as to maximize the available headspace.
3. Pullthe packaging away from itscontents to create an area which will be used to accept the needle.
4. Apply an adhesive-backed septum to the area of the package through which the needle will be
inserted –ensure the package is clean and dry in the area where the septum is applied (the septum
creates a seal around the needle to avoid atmospheric oxygen ingress).
5. Pierce the septum with the needle and keep the needle in the area created, awayfrom the product.
Do not allow the needle to exit the other side of the package (if this happens, discard the package
and start over with a new one).
6. Set the analyzer test time as mentioned in section 5.4.1. Initiate the measurement by pressing the
green ‘TEST’ button –do not move the needle during the measurement.
7. If the oxygen/carbon dioxide concentration reading is still changing after the test time expires,
consider extending the test time as mentioned in 5.4.1.
8. Once the measurement stabilizes, the test is complete. If connected, the external printer will
document the test results.
9. Withdraw the needle from the package and place back in the sample probe holder on the side of
the analyzer –dispose of tested packages as instructed.
10. Document test results in other ways if so instructed.
11. Visually inspect the upstream side of the filter after each test. If it begins to collect product,
exchange it for a new filter. Passing product through the filter may cause damage to the
analyzer which will not be covered under warranty.
12. Perform an Air Calibration at regular intervals, see section 6.1.
