3. DESCRIPTION
The OdaLog® is a compact portable gas data-logger designed by industry-proven manufacturer Thermo
Fisher Scienc – the gas detecon specialists for harsh environments, such as the wastewater industry.
With superior sealing and heavy-duty materials, this instrument is corrosion-resistant, durable, and
reliable.
The new generaon OdaLog® Logger picks up where its respected predecessor le o. With super-low
power consumpon coupled with a long-life lithium cell power source, baery life will exceed 12 months
in most cases, taking "low maintenance" to a whole new level.
New and faster infrared wireless communicaon and magnec switches enable the OdaLog® to be easily
calibrated and congured and download logged data without disassembly.
The extra-large, easy-to-read LCD makes the OdaLog® simple to use and interpret instrument data and
sengs on-site. The instrument's main features can be viewed on-screen, such as gas readings,
temperature, % of memory used, logging mode and me intervals, and a baery level indicator.
OdaLog® interfaces with Thermo Fisher's dedicated, easy-to-use OdaStat-G™ soware package that brings
logged data into the oce environment in a user-friendly format.
WARNING
The OdaLog® Gas Logger is not designed to operate as a safety device. When entering conned
spaces and toxic hazard environments all appropriate regulaons and occupaonal health and
safety precauons should be strictly adhered to. If unsure of potenal hazards or safety standards,
seek advice from your workplace occupaon health and safety department or Government
regulatory body.
The use of Lithium Baeries other than lithium baeries listed in Table II will invalidate the intrinsic
safety approval.

6.8.3. Precauons are required when using OdaLog® I.R communicaon.
The Infra-Red communicaons system used by the OdaLog® to communicate and transfer data to a
computer has been designed as a fast and convenient method to download informaon. Like all
communicaon systems, the Infra-Red system has some vulnerabilies that can interfere with normal

OdaLog® L2 – Gas Logger User Manual
P/N: 10-1000 Revision G, January 2024 Page | 13
communicaons as more portable devices are ulising this technology. As a result, the possibility of
interference between devices is increasing, and precauons should be taken to ensure that
communicaons between the OdaLog and PC are reliable and trouble-free.
Condions that have the potenal to disrupt OdaLog® to computer communicaons are:
Infra-Red ports built-in to the PC/Laptop or connected to any nearby computers should disabled.
Infra-Red ports on organisers, phones, modems, etc., that have been acvated or are in use.
Infra-Red ports on printers.
Strong light sources near the OdaLog during communicaons
Infra-Red remote-control devices from TVs, air condioners, etc.
Note: The OdaLog® is only suscepble to communicaon interference when placed into "IrDA" mode.
No other device or source of Infra-Red interference can aect the OdaLog® if the user has not
placed the OdaLog® into the "IrDA" mode.
6.8.4. Steps to ensure reliable I.R communicaon.
Posion the OdaLog® correctly with respect to the Infrared Data Communicaon Link, as shown
in Figure 9.
If you are using a computer with an Infra-Red port aached (other than the Infrared Data
Communicaon Link used with the OdaLog®), disable this port to prevent any Infra-Red
transmissions from it.
Ensure that other devices with Infra-Red ports (phones, other computers, organisers, etc.) within
about 10 metres of the OdaLog® do not have their Infra-Red ports acvated.
Ensure that strong light sources are not directed onto the OdaLog® while the instrument is in
"IrDA" mode.
When changing the conguraon of the OdaLog® using the OdaStat-G™ soware package, always
read back the sengs from the OdaLog® aer they have been changed to ensure they have been
received correctly.
Note: In severe cases of Infra-Red interference, the OdaLog® may stop responding. If this occurs,
contact your nearest OdaLog® distributor or service centre for advice on restoring normal
operaon to the OdaLog®.
6.8.5. Communicaons Set-up
If using a USB-based IR adapter, ensure the drivers are installed BEFORE connecng the device.
Connect the IrDA device to your PC and install the OdaStat-G™ soware package.
Using In-built IrDA Devices
While some infrared ports (laptops mainly) are compable with the OdaLog, due to the variaon in
manufacturers, drivers and communicaon protocols, users oen experience issues connecng
and/or downloading reliably. For this reason, Thermo Fisher strongly recommends that users only
aempt to connect to the OdaLog via the IR device supplied by us. Only advanced users should
aempt to use inbuilt IR ports. If dicules arise, ensure the inbuilt IR adapter is disabled, and
revert to using the provided adapter.
