SAFETY INSTRUCTIONS

The dose rate measuring range of the RadEye GF-10 is limited
to 3 Sv/h (300 R/h for RadEye GF).

Correct dose integration is performed only, if the instrument
does not display over load “OVERLOAD”.

The device is not intended for use as a legal personal dose
meter.

The RadEye GF/GF-10 is not well suited for pulsed radiation.
There will be a significant under estimation at dose rates dur­ing pulse of more than 1.7 R/h / 17 mSv/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 RadEye GF / GF-10.

The instrument must not be used in explosive atmosphere.

1. Introduction

The pocket sized RadEye is a sensitive and rugged device to
measure the ambient equivalent dose rate of gamma and X-ray
radiation. . In this context, it is important to note, that users
may select “R/h”, “Sv/h” “Gy/h” or “rem/h” as a display unit,
with the understanding that the energy response characteristic
is not altered by this selection. Within the RadEye GF/GF-10
the relation 1 R = 1 rem =10 mSv = 8.77 mGy/h is used.

The characteristic feature of the RadEye GF/GF-10 is the use
of sophisticated low power technology components and mi­croprocessor based fully automatic self-checks. No mainte­nance is required.

The last 1600 mean and maximum values of the dose rate are
recorded internally and can be read out via serial interface.

Additionally the device 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 con­figured to be invisible and inaccessible by the user.
Thus, the instrument can be configured to both, an extremely
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 is delivered in a folding paper box together with
two AAA cells and an operating manual.

A rubber protection sleeve, a holster and an earphone may be
added optionally.

Ordering information for the accessories see chapter 10.

2.2 Inserting the battery

The two AAA-Alkaline cells as delivered with the instrument
allow up to 900 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 its groove.

• Switch on the unit again. (see chapter 2.4).

2-2 DB-083 E RadEye GF-Series
Le/Ff 20.07.2015

The instrument continues working in the operating mode set
last.
The measured values in the history memory remain stored.
The real time clock for time stamp of history values and log­book continue operation if batteries are exchanged immediate­ly. If Real Time Clock is set, actual time and date is displayed
for 3 s.
RTC will always be reset, if instrument is stored without bat­teries for more than 10 seconds.
History data and measurement parameters are stored perma­nently, even if batteries are removed.

RTC information is only required, if the instrument switched
off and on during operation and if correct timing information
for history and logbook entries is needed.

The first alarm thresholds for dose rate is around 200 - 500 %
above the typical normal background and allow sensitive, but
false alarm free dose rate monitoring with a reasonable fast
response time. The alarm thresholds for the dose are set to the
maximum possible values, thus being deactivated. With the
setting of the history recording interval of 120 s, the last 52
hours of operation will be stored in the history memory.

These default values are reasonable for the majority of appli­cations. For special applications, the parameters (except cali­bration parameters) can be changed with the help of the op­tional PC-program “RadEye.EXE” from V1.30 and the cable
42540/29 or 42540/26. Furthermore, additional monitoring
modes can be activated.

The calibration parameters can only be changed in the factory
using special software tools.

3. Configuration

3.1 Menu functions

To enter the operating menu, press the “Menu/◄” key.
Scrolling through the single menu options is effected by the
▲/▼ arrow keys.
The display returns to its initial default setting in case no key
has been activated for more than 10 seconds.

A “”behind some menu items identifies the corresponding
function as active.

The menu consists of a main menu and several sub menus.

Using the PC-Software and an interface adapter, any of the
functions can be hidden. This allows the user to be given only
the functions necessary to accomplish his measurement duties,
thus simplifying the handling considerably.

The ▲/▼ keys are used to scroll through the menu.

To select a menu option, release the ◄/Menu key as the re-
spective menu option has been reached.

4.5 Process description for detection of radiation sources

Direction of maximum response

To detect hidden radiation sources, the dose rate alarm thresh­old must be set to the lowest value that does not produce fail
alarms. This is typical a value of 0.3 µSv/h to 0.5 µSv/h.

4-4 DB-083 E RadEye GF-Series
Le/Ff 20.07.2015

Due to its almost 100 times higher efficiency, the RadEye
PRD is more suited for this task, than the RadEye GF/GF10.

Subsequently, the operator passes the object while keeping
thereby the distance between the monitor and the object to be
checked as small as possible.
With an alarm occurring, the operator should move the in­strument while observing the display in order to localize the
position of the source. Please note that the alarm can occur up
to a few seconds after passing the nearest distance to the
source.
If the alarm disappears after a few seconds, this alarm is to be
considered as a statistically released false alarm.
In case a radiation source has been detected, the radiation in­tensity is indicated. (See chapter 3.2).

4.6 Earphone

For alarming in noisy environments or for undercover investi­gations an earphone is available. See ordering information
page 2.1.

The earphone is connected at the bottom of the instrument

The RadEye car- and wall holder combines several functions.

(1) Mechanical holding device for instruments of the

RadEye-family

(2) Accumulator charger unit with temperature controlled

charging of NiMH accumulators in the device

(3) Infrared interface for direct connection to the serial in-

terface of computers

(4) Alarm contact for connecting alarm indicators up to a

power of 24W (at 24V, see RadEye area monitor
42506/80)

Before plugging the RadEye into the Car holder the rubber
protection plug at the phone jack has to be opened:

Carefully remove the protection sleeve and open the phone
jack
