SAFETY INSTRUCTIONS
The RadEye G20 is suited to perform highly accurate dose
measurements. It is however not intended for use as a legal
personal dose meter.
The RadEye B20 is not well suited for pulsed radiation. There
will be a significant under estimation at dose rates during
pulse of more than 0.2 R/h.
In case the dose rate measuring range is exceeded, the value of
the upper end of the dose rate measuring range is used for the
dose integration.
The instrument must not be used in explosive atmosphere.
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 G20.
The RadEye G20 is not suited for pulsed photon radiation.

Iw/Tr/Ff 26.11.2012
1. Introduction
The instruments of the RadEye G20 series are modern compact survey meters for sensitive gamma and x-ray dose rate
measurements. The instrument incorporates a sensitive GM
pancake tube detector allowing the dose rate measurement
from background levels. ER-versions extend the measuring
range up to 100 mSv/h (10 rem/h respectively 10 R/h).
RadEye G20-10 and RadEye G20-ER10 are energy compensated according to the SI-standard units of ambient dose
equivalent H*(10) (= “deep dose”) and show a flat response
from 17 keV to 1.3 MeV. RadEye G20 and RadEye G20-ER
are energy compensated according to roentgen units (40 keV
to 1.3 MeV). In this context it is important to note, that users
may select “R/h, Sv/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 G20 family the
relation 1 R = 1 rem =10 mSv is used.
The last 1600 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 G20 logs the last 250
alarms, errors and changes of the configuration. All events can
be read out via serial interface.
RadEye G20 DB-067 E 1-1

A real time clock is provided to add a time stamp to all buffer
data. The characteristic feature of the RadEye G20 is the use
of sophisticated low power technology components and microprocessor 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 G20 instruments are delivered in a box together
with two AAA cells and an operating manual.
Ample space is provided for a data cable or a test adapter.
.
Ordering information for accessories see chapter 11
RadEye G20 DB-067 E 2-1
Iw/Tr/Ff 26.11.2012
2.2 Inserting the batteries
The two AAA-Alkaline cells as delivered with the instrument
allow about to 900 h with RadEye G20/G20-10 respectively
700h with RadEye G20-ER/G20-ER10 of normal operation.
AAA size rechargeable batteries can be used as well.
• Switch off the measuring instrument.
• 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 rubber
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).
2-2 DB-067 E RadEye G20
Iw/Tr/Ff 26.11.2012
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 without
delays. If Real Time Clock is set, actual time and date is displayed for 3 s (see chapter 2.4).
After power on the RadEye first display zero dose rate. After
the first detector pulse the measurement will be started.
If correct timing information of logbook and history is required,
the Real Time Clock should be set by means of the PC-program
or via menu function “Set Time/Date”.
To keep RTC running during battery exchange, batteries must
be exchanged without delays.
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.
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 mechanical shocks.
For mounting of the sleeve first put the instrument into the bottom of the sleeve. Then pull lower edges of the sleeve, one after
the other into its right position.

2.4 Switching the unit on
(example refers to G20-10, calibrated in rem/h)
To switch on the RadEye G20, keep the “On/▼” button pressed
for at least one second. The sound generator (beeper) is initiated.
After switching the unit on, the RadEye G20 starts working
with the parameters previously selected (operation mode, calibration factor, alarm thresholds etc.).

With the setting of the history recording interval of 120 s, the
last 52 hours of operation will be stored in the history memory.
The parameters (except calibration parameters) can be changed
with the help of RadEye buttons and the optional PC-program
“RadEye.exe” V1.30 and the cable 42540/29 or /26.
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
“▲/Info” and “▼/On” keys.
The display returns to its initial default setting in case no key has
been activated for more than 10 seconds.
A “
9” to be found behind some menu options means that the
respective function is active.
The menu consists of a main menu and several sub menus. Some
menu options are disabled for some operation modes and display
modes.
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.
To select a menu option, release the “◄/Menu” key as the respective menu option has been reached.

This submenu is used to select the measuring unit for ratemeter
and scaler measurements.
Attention:
Whether the instrument measures dose rate (G20 or G20-ER) or
dose equivalent (G20-10 or G20-ER10) depends on the hardware
of the energy filter and cannot be changed by the selected unit.

3.4 Alarm thresholds
There are two alarm thresholds each allocated to dose rate and
dose.
In order to avoid dose alarms while using the instrument exclusively as a rate meter, the dose alarms can be set to the maximum
level.
Configuration of the alarms is possible via infrared interface or
via the menu.
As to the alarm activation, please also read chapter 4.2.
3.5 Setting alarm thresholds
The menu options Alarm Dose Rate and Alarm Dose allow
the alarm thresholds to be modified. For this setting, the user has
255 seconds time. Changing the value is effected by pressing the
“◄/Menu” (Change) button if the corresponding “Alarm” is selected:
To increment the number press the “▲/▼” arrow keys. To go on
to the next digit or to quit the edit mode, menu use “◄/►” keys.
Once the last number has been set, quit the editing mode by pressing the “Exit”-key. Then, the value set is saved and after 10s the
unit returns to the basic display.
