3.0 CO2Analyzer Accessories
3.1 Optional Products
The CO2Analyzer has a number of optional products for purchase
which enhance the usability and enable further analysis of data and
reading information.
NOTE: For more information on the features listed in this section
please contact your nearest Bacharach Service Center.
3.1.1 PC Software (Optional)
The software enables the user to maximize the operation of the
incubator analyzer. Instrument readings and event log data may
be uploaded to a PC for further analysis and exported to other
applications such as MS Excel. It enables direct communication with
the unit, features a simple download facility and is fully compatible with
the latest Microsoft operating systems (32-bit only). A USB cable is
provided with the software.
3.1.1.1 Event Log
The instrument incorporates the ability 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 software. It cannot
be viewed on the analyzer screen. Applicable events are stored in the
event log automatiaclly, meaning 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.

Instruction 19-9339 10
3.1.2 Temperature Probe Reading (Optional)
The instrument has the ability to read and display two temperature
readings via optional temperature probes (P/N 0019-0611). When
a temperature probe is fitted to one of the temperature ports on the
top of the instrument, the display will automatically show the current
reading and a temperature probe icon will be displayed.
The display can also be changed to show a T1- T2calculation by
pressing the appropriate soft-key. The current mode of operation can
be identified by normal or inverse status of the soft-key, where inverse
indicates that the option is active.
NOTE: The T1- T2result is not stored as part of the reading.
The operator can also choose to display the reading in either
Centrigrade or Fahrenheit using the temperature option accessed from
the Settings Menu.

5.0 General Operational Instructions
5.1 Switching the Instrument ON
1) To switch on the instrument, press the “ON/OFF” key briefly. There
will be a short beep and a slight pause followed by the Bacharach
logo.
2) The power on self-test will then commence (approximately 60
seconds).
3) If there are no warnings to display the instrument will continue to
the MAIN READ SCREEN.
5.2 Switching the Instrument OFF
1) Purge the analyzer with fresh air. Run the pump for approximately
30 seconds or until the readings have returned to normal levels.
NOTE: Before the instrument is switched off, a clean air purge should
be performed. This ensures that the instrument is free from
gas and ready for the next measurement. This final purge is
especially important for the oxygen sensor as it may degrade
if stored when contaminated with gas.
2) To switch off the instrument, press the “ON/OFF” key briefly.
NOTE: If the “AUTO OFF” setting is set to “YES”, the analyzer will
switch off automatically after 10 minutes if not in use.

have completed, the analyzer will display the “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.

The soft-key “DELETE” will delete the last character typed.
Alternatively, the sequence can be re-typed before the “ENTER” key
is pressed and the existing numbers will be replaced by the new
sequence.
NOTE: The instrument will not allow invalid data to be entered; this
should be deleted and re-entered.
5.6 Changing Between Parameters
By default, the instrument displays the MAIN READ SCREEN (for gas
measurement). This shows the CO2reading along with the optional
readings (O2, %RH, etc). The instrument will return to this screen after
power on or when returning from the menus. The “SCROLL” keys can
be used to switch to another measurement screen, i.e. temperature or
humidity. Continue to press the “SCROLL” key to return to the MAIN
READ SCREEN.
5.7 Memory
The memory SHOULD NOT be used as a permanent storage medium
and any important data 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.
5.8 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 in order
to help prolong the life of the O2cell.
