SAFETY INSTRUCTIONS
Due to the rather high detector sensitivity the dose rate meas-
uring range of the SENTINEL RadEye G is limited to 10 R/h.
A correct dose integration is performed only, if the instrument
does not display over load “OVERLOAD”
The SENTINEL RadEye G is suited to perform highly accu-
rate dose measurements at low to medium dose rates. It is
however not intended for use as a legal personal dose meter.
The SENTINEL RadEye G is not well suited for pulsed radia-
tion. There will be a significant under estimation at dose rates
during pulse of more than 0,2 R/h.
Do not use the unit if error messages appear on the screen.
The earphone connector at the bottom side of the instrument
must be exclusively used by equipment that is specified for
use with SENTINEL RadEye G.

1. Introduction
The pocket sized SENTINEL RadEye G is a sensitive and
rugged device to measure the photon exposure rate (R/h) of
gamma and X-ray radiation.
The characteristic feature of the SENTINEL RadEye G is the
use of sophisticated low power technology components and
microprocessor based, fully automatic self checks. No mainte-
nance is required.
The SENTINEL RadEye G incorporates a sensitive GM tube
detector allowing the detection of low to medium radiation
levels.
While in some of the pictures in this documentation the meas-
uring unit “µR/h” is displayed, the measuring range of the
SENTINEL Rad Eye G is restricted to 0.01 mR/h – 10 R/h.
The last 1600 mean and maximum values of the dose rate and
count rate are recorded internally and can be read out via serial
interface.
Additionally the SENTINEL RadEye G logs the last 250
alarms, errors and changes of the configuration. All events can
be read out via serial interface.

A real time clock is provided to add a time stamp to all buffer
data.
All or selected menu functions described in 3.1 can be con-
figured to be invisible and inaccessible by the user.
Thus the instrument can be configured to both, an ex-
tremely simple mode allowing just LCD-illumination and
alarm acknowledgment to a very versatile mode for the
more experienced user.

2.2 Inserting the battery
The two AAA-Alkaline cells as delivered with the instrument
allow up to 500 h of normal operation.
AAA size rechargeable batteries can be used as well.
•Switch off the measuring instrument.
•If supplied, remove rubber sleeve.
•Open the cover of the battery compartment.
Use of a coin is recommended.
•Exchange the batteries according to the shown polarity.
•Close the compartment cover, hooks first, care for the rub-
ber seal being in it’s groove.
•Switch on the unit again. (see chapter 2.4)
The instrument continues working in the operating mode set
last (see chapter 3.2).

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).
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.
RTC information is only required, if the instrument is
switched off and on during operation and if correct timing
information for history and logbook entries is needed.
For the last power on interval, the relative time information of
logbook and history is corrected to actual PC clock time dur-
ing read out. In these cases the setting of the clock is not re-
quired.

2.3 Mounting of the protection sleeve
The rubber protection sleeve improves ruggedness to me-
chanical shocks.
For mounting of the sleeve first put the instrument into the top
of the sleeve. Then pull lower edges of the sleeve, one after
the other into it’s right position.

2.4 Switching the unit on
To switch on the SENTINEL RadEye G, keep the ON button
pressed for at least one second. The sound generator (beeper)
is initiated.
The SENTINEL RadEye G starts working with the parameters
previously selected (operation mode, calibration factor, alarm
thresholds etc.).
If the real time clock is set, actual time and date is displayed
for 3s.
