Every 10 seconds, the NOX monitor of the EasyNOₓ saves a complete record of all relevant measured values, timers, and status values to a daily log on the memory card inserted in the EasyNOₓ. Selected measured values of the daily logs can be visualized in the NOX History view of the NOX monitor (see section History). Via the USB interface of the EasyNOₓ, each daily log can be exported as a CSV file to a USB flash drive (see section Export).
