3 DESCRIPTION
The OdaLog® is a compact portable gas data-logger, designed by industry-proven manufacturer Thermo Fisher
Scientific Australia – the gas detection specialists for harsh environments, such as the waste water industry.
With superior sealing and use of heavy-duty materials, this instrument is corrosion-resistant, durable and
reliable.
The new generation OdaLog® Logger picks up where its respected predecessor left off. With super-low power
consumption coupled with a long-life lithium cell power-source, battery life will exceed 12 months in most
cases, taking ‘low-maintenance’ to a whole new level.
New and faster infrared wireless communication, as well as magnetic switches enables the OdaLog® to be easily
calibrated, configured and the download of logged data without the need for any disassembly.
The extra large, easy to read LCD makes the OdaLog® simple to use and interpret instrument data and settings
on-site. The instrument main features can be viewed on-screen, such as: gas readings, temperature, % of
memory used, logging mode and time intervals, as well as a battery level indicator.
OdaLog® interfaces with Thermo Fisher Scientific’s own dedicated, easy to use OdaStat-G™ software package
that brings logged data into the office environment in a user-friendly format.
WARNING
The OdaLog® Gas Logger is not designed to operate as a safety device. When
entering confined spaces and toxic hazard environments all appropriate
regulations and occupational health and safety precautions should be strictly
adhered to. If unsure of potential hazards or safety standards, seek advice from
your workplace occupation health and safety department or Government
regulatory body.
The use of Lithium Batteries other than lithium batteries listed in Table 1 will
invalidate the intrinsic safety approval.

5 QUICK OPERATIONAL GUIDE
This section describes a brief operating procedure for the OdaLog® instrument, covering the basics of all major
functionality. For more detail, refer to corresponding information in Section 6.
5.1 Switch On
Press & hold button down, “ON” will count down ON 3-2-1, release the button when the ‘test’ screen appears
(all segments visible/black as shown). The unit will progress through “STATUS” screens then display the
“INST” (Instantaneous reading) screen. (See Section 6.1)
5.2 LCD Layout Overview
1. Lower 7-segment characters – Displays gas readings and status values – usually numerical digits,
some supplemental menu headings and prompts.
2. Upper 14-segment characters – Displays menu headings, prompts and other visual feedback – usually
alphabetic characters, some numerical values displayed on some screens
3. Battery Level Indicator – Displays the battery levels (4 stage depletion, see Section 6.12)
4. Communications Symbol – Indicates if the instrument is successfully connected and transferring data
(i.e. for downloading log and changing parameters and settings in the OdaStat-G™ software package).
5. Logging Symbol – This symbol flashing indicates that the instrument is Logging – Note: flashing
interval does not indicate logging interval (See Section 6.5 for more information on logging)
6. % - This symbol is used to show any units or screens that display units as a percentage (e.g. Memory
usage, some gas types are displayed % Volume).
7. Temperature units – when displaying the temperature readings on screen in degrees Centigrade or
Fahrenheit, depending on the setting chosen in the OdaStat-G™ software package [Default = º C]
8. Gas Reading units – Indicates if gas readings shown are in ‘parts per million’ or ‘parts per billion’
[‘ppb’ disabled in OdaLog® Logger Type L2 series instruments].
