OMEGA OM-21 (01) PDF Document

To configure the OMEGA OM-21, follow these steps:

1. Connect the data logger to a PC via the USB port. The logger status LEDs will blink for two runs.

2. When the Window Automatic playback is displayed, click on “Open folder to view files.”

3. Open the file named “PDF Logger Configuration Tool. exe”.

4. The default language is English, but you may change it to German, French, Italian, or Spanish. The generated PDF report will use the chosen language.

5. Configure your desired parameters (Temp. Unit, Password, Company Name, Alarm types, etc.).

6. Press “Save” to confirm the setting. The logger will auto-synchronize to your PC time.

7. Close the setup window and remove the logger from the PC USB port.

Note: Anytime before the logging is started, the logger can be programmed several times. If the logger is locked by password after the first configuration, the password will be required to program the logger again.

After the OMEGA OM-21 is programmed, seal the zipped bag well. Press the “START” key for 2 seconds to start the logging. The Red LEDs will flash three runs to indicate the logging is activated.

Once started, the green LED will blink every two seconds. Note that to activate the logging function, there is a delay of 5 minutes after pressing the START key, meaning the first data is logged 10 minutes after pressing the key.

To stop the logging, press the “STOP” key for 2 seconds. Alternatively, you may directly plug the logger into a PC USB port to stop the logging and generate the PDF file.

It takes a few seconds to generate the PDF report, during which the status LEDs will blink. Adobe Reader software is required to view the report.

Note: If the logger is taken out from a -30°C freezer, please leave it in air for a few minutes before plugging it into a PC to generate the PDF report.

The LED indicators on the OMEGA OM-21 function as follows:

Low/High: The Red LED blinks when the measuring set limit value is exceeded.

OK (Standby): The Green LED blinks triple every 5 seconds when the logger is in standby mode but has not yet started to log readings.

OK (Logging): When the logging function is started, the Green LED blinks every 2 seconds.

Low bat. symbol: The Red LED blinks every 2 seconds when battery power is too low to maintain accurate logging.

The OMEGA OM-21 offers the following alarm types:

Single: A LED alarm is triggered immediately when the measured value exceeds the alarm threshold.

Cumulative: A LED alarm is not triggered when the measured value exceeds the alarm threshold, but only once the overall average value during the alarm delay duration exceeds the alarm threshold.

Disable: No LED alarm function during the logging process.

Note: No matter what alarm type is picked up, the LED will not stop flashing once it is triggered as ON even if the measured value later returns to the normal range.

For the “Single” alarm type, the preset alarm delay time is always zero.

For the “Cumulative” alarm type, the alarm delay time is adjustable from 5 minutes to 2 hours.

For example, to activate a LED flashing when the 30-minute average value of a hazardous alarm delay period is higher than 8°C, you should program the alarm delay as 30 minutes, the alarm type as cumulative, and the range as 2~8°C.
