SAFETY INSTRUCTIONS
Dose integration is performed only, if the instrument is in a
dose rate measuring mode (R/h, Rem/h, Sv/h, Gy/h). In case
the measuring range is exceeded, the value of the upper end of
the dose rate measuring range is used for the dose integration.
The measuring value and range depends on the properties of
the connected external detector. It is the responsibility of the
user or supervisor to select the correct probe.
Extension of the probe specific default measuring range can be
achieved by individual calibration and determination of the
dead time behavior.
The RadEye GX, respectively the connected Geiger Mueller
probes are not well suited for pulsed radiation. Depending on
the sensitivity of the detector and the conditions of the pulsed
field, there can be a significant under-response.
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 RadEye GX.

1. Introduction
The RadEye GX is a modern compact multi-purpose meter for
external Geiger Mueller tubes.
The last 1500 mean and maximum values of the count rate or
dose rate are recorded internally and can be read out via serial
interface. Additionally the RadEye GX 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. The characteristic feature of the RadEye GX is the use of
sophisticated low power technology components and micro-
processor based fully automatic self checks. No maintenance
is required.
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. Installation and start-up
2.1 Scope of delivery
The RadEye GX is delivered in a box together with two AAA
cells and an operating manual.
Ordering information for accessories see 9:
2.2 Inserting the battery
The two AAA-Alkaline cells as delivered with the instrument
allow about 500 h of normal operation.
AAA size rechargeable batteries can be used as well.
AAA size rechargeable batteries can be used as well. The bat-
teries must be of the same type and the same charge level. Do
not mix different types or new and partially discharged cells.

Switch off the measuring instrument.
Remove rubber sleeve.
Open the cover of the battery
compartment.
Use of a coin is recommend-
ed.
Exchange the batteries ac-
cording to the shown polarity.
Close the compartment cover, hooks first, care for the rub-
ber seal being in its 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).
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.

2.3 Mounting of the protection sleeve
The rubber protection sleeve improves ruggedness to mechan-
ical shocks.
For mounting of the sleeve first put the BNC connector into
the hole at the top of the sleeve. Then pull lower edges of the
sleeve, one after the other into the correct position.

2.4 Switching the unit on
To switch on the RadEye GX, keep the ON button pressed for
at least one second. The sound generator (beeper) is initiated.
The start screen is displayed for two seconds.
After switching the unit on, the user is requested to confirm
the external probe that had been connected when the instru-
ment had been used the last time. Alternatively he can change
to another probe from the list of probes.
If the real time clock is set, actual time and date is displayed
for 3s.

When the counter tube is selected the RadEye GX first dis-
plays 0.00 cps. After the first detector pulse the measurement
will be started. The RadEye GX starts working with the pa-
rameters previously selected (operation mode, calibration fac-
tor, alarm thresholds etc.). The selected probe is displayed in
the top line of the LCD.
Unless otherwise specified by the customer when placing the
order, the following values are set by the factory before delivery:
