4.6.10 Dose Profile
The EPD stores Hp(10) and Hp(0.07) dose to a resolution of 1
µ
Sv in non-volatile
store so that a profile of the dose over time can be recreated. The interval
between stores is set-up via the IR communications link.
Both Hp(10) and Hp(0.07) dose information is stored as a dose profile, the
minimum interval between entries in the dose profile is adjustable between 2
seconds to 35 hours, in 2 second intervals. The store holds up to 579 records for
transitions up to 127
µ
Sv or less.
Note:
A dose profile interval of zero seconds turns off the dose profile function.
Dose profile can only be read via the IR communications link. Dose profile may
be synchronised to a particular time in the future, e.g. hourly logging on the hour.
Note
: The EPD has no concept of real-time but maintains a one-second tick that
is valid as long as the EPD is powered and not reset.
