The OM-EL-USB-CO and OM-EL-USB-CO300 are standalone data loggers that measure and store up to 32,510 carbon monoxide (CO) readings over a 0 to 1000 ppm (OM-EL-USB-CO) or 0 to 300 ppm (OM-EL-USB-CO300) measurement range and -10 to 40°C (14 to 104°F) operating temperature range. The user can easily set up the logging rate and start time, and download the stored data by plugging the data logger into a PC’s USB port and running the Windows control software. The data can then be graphed, printed and exported to other applications. The data logger is supplied complete with a long-life lithium battery. Data is stored in non-volatile memory and is retained when the battery is empty. A bright red LED will flash and a buzzer can sound when a preset warning level has been exceeded.
## **IMPORTANT SAFETY WARNING**
Do not attempt to use the OM-EL-USB-CO or OM-EL-USB-CO300 data loggers without reading and understanding the documentation. Carbon monoxide monitoring is a complex procedure. The user should consult a qualified expert if there is any doubt as to the safety of the application.
The OM-EL-USB-CO and OM-EL-USB-CO300 are professional measuring instruments designed to record carbon monoxide (CO) gas levels for later analysis. They are not alarm/safety/warning devices and should not be used in this capacity for the following reasons:
1. The lights and sound emitted by the OM-EL-USB-CO or OM-EL-USB-CO300 to indicate a high level of CO do not provide adequate warning to those in the surrounding area that a high level of CO has been recorded.
2. The battery life of the OM-EL-USB-CO or OM-EL-USB-CO300 during audible and visual indication of a high level of CO will rapidly diminish and will therefore only be active for a short period of time.
3. The OM-EL-USB-CO or OM-EL-USB-CO300 takes a sample reading at intervals as set by the user for recording/monitoring/analysis purposes. Dangerous levels of CO will not register with the device until a sample reading is taken.
4. Due to the limitations of the device as a professional instrument, it is left to the user to set the light and sound alarms indicating the presence of CO. Therefore the instrument can be set up to provide NO form of warning. Carbon monoxide is poisonous. It is a clear, colorless gas that has no smell or taste and can be lethal even in very low concentrations. It can injure or kill people and animals who are not adequately warned of its presence. In areas where the safety of humans and animals is a concern, a domestic or industrial CO detector/alarm designed to a nationally approved quality standard with features such as a high decibel alarm or siren and a clear visual warning specifically designed to provide adequate warning of dangerous CO levels should be installed, used and maintained.

**OM-EL-WIN-USB (CONTROL SOFTWARE)** The OM-EL-WIN-USB control software is supplied free of charge with each data logger. The software is used to set-up the data logger as well as download, graph and export data to Excel. **OM-EL-USB-CO shown smaller than actual size. Audible Alarm:** The audible alarm will sound once per second when the warning threshold has been exceeded. To disable the warning, remove the cap from the data logger. The audible warning will sound once every 60 seconds when there is a low battery condition. This indicates that the battery must be replaced.
