OWL +USB is a portable domestic electricity monitor which can work as an instantaneous power consumption monitor as well as a data logger which stores the daily average power consumption over the past 2 years.
OWL +USB is also equipped with a USB port which can connect to a PC for data transfer. Both the instantaneous and stored data (30 days detailed info) can be uploaded to the PC for further analysis. Not suitable for Apple Mac PC's
OWL +USB receives data from its associated transmitter/sensor and converts the current consumption (single, twin or 3 phase, subject to installation & connection of appropriate number of CTs) to total power consumption, cost of electricity and green house gas emissions. The consumption data is available as a real-time value, accumulated value, and average daily/weekly/monthly values.

OWL +USB supports alarm functions to alert the user when the power exceeds the user setting, In addition, it also measures indoor temperature and shows all parameters on a large liquid crystal display (LCD).

When OWL +USB is not linked to a PC, OWL +USB will act as a data logger. In every minute, OWL +USB will calculate and store the average current of that minute with date-time stamp. OWL +USB can store up to 30 days of the 1-minute average data. When the 30 days buffer is full, the new data will replace the oldest data.
When the unit is connected to a PC with the application software opened, OWL +USB will start uploading from the oldest data to the latest data.
OWL +USB will upload data for 5 seconds and then wait for the PC to respond. If the PC gives a correct feedback, OWL +USB will transmit data for another 5 seconds. The successfully uploaded data will be moved out from the transmit buffer and will not be uploaded again.
If OWL +USB is disconnected from the PC (unplug the USB cable or close the PC program) before it finishes uploading all the data, the next time when OWL +USB is connected to the PC, it will upload from the previously failed 5 seconds slot.
It will start uploading from the record at the beginning of the 5 seconds slot and then upload the remaining data plus the newly added data.
After all the stored data is transferred to the PC, OWL +USB will transfer the real time data it received from the remote sensor.
