2 Functional Description
2.1 Readings screen
Attention : Tracerco recommends that the time before screensaver activation should be kept as low as practical as
long periods of screen activity reduce the lifetime of the screen.
PEDs have the following display modes:
•
Combined dose and dose rate (this is the default screen layout)
•
Dose rate only (includes peak dose rate)
•
Dose only (includes stay time).
PEDs also have an option to flip the screen. The display modes are as follows:
