3.5.8 Recording to USB stick (logging)
Device data can be recorded to USB stick (2.0 / 3.0 may work, but not all vendors are supported) anytime. For
specicationsoftheUSBstickandthegeneratedloglesrefertosection„1.9.6.5. USB port (front side)“.
TheloggingstoreslesofCSVformatonthestick.ThelayoutofthelogdataisthesameaswhenloggingviaPC
with software EA Power Control. The advantage of USB logging over PC logging is the mobility and that no PC is
required.TheloggingfeaturejusthastobeactivatedandconguredintheMENU.
