Thermo Scientific RadEye GX Operating Instructions Manual page 17

The measured values in the history memory remain stored.
The real time clock for time stamp of history values and log-
book continue operation, if batteries are exchanged without
delays. If Real Time Clock is set, actual time and date is dis-
played for 3 s (see chapter 2.4).
After selection of the counter tube the RadEye GX first dis-
play 0.00 cps. After the first detector pulse the measurement
will be started.
If correct timing information of logbook and history is re-
quired, the Real Time Clock should be set by means of the PC-
program.
To keep RTC running during battery exchange, batteries must
be exchanged without delays.
RTC will always be reset, if instrument is stored without bat-
teries for more than 10 seconds.
History data and measurement parameters are stored perma-
nently, even if batteries are removed.
Even without RTC information the relative time information
of logbook and history is corrected to the actual PC clock time
during read out unless the batteries had not been removed
between the event and the data read out.
