Operating manual

Dear users,
You had chosen well if purchased a device of
“ECOTEST” trademark manufactured by “Sparing-Vist
Center”. Your device is easy to use and can be applied for
household purposes without special training of the user.
Should any questions arise, please contact our managers by
telephone [phone], fax [phone]
or e-mail [email protected].
We would greatly appreciate to receive your comments
and suggestions on its operation. The device is under
18-months (free of charge) warranty maintenance.
Best regards, International Sales Department

Dear users,
We would like to draw your attention to the delivery kit of
the UDKG-01A “Gamma Sapiens” intellectual gamma radiation
detector that includes two AAA batteries. However, the power
for operation can also be supplied by two ААА nickel-metal-
hydride (NiMH) rechargeable batteries of no less than 800 mАh
capacity instead of batteries that come with the device. You can
buy these rechargeable batteries and their charger at any retail
outlet. Famous manufactures, such as Varta, are highly
recommended.
Choose an automatic battery charger, preferably with a
function to control charging of each rechargeable battery.
Charge rechargeable batteries only when they are fully
discharged. Recharging partially discharged rechargeable
batteries on a repeated basis minimizes considerably their
lifespan.
Do not use one rechargeable battery along with a non-
rechargeable one to power the gamma radiation detector. This
will lead to the rechargeable battery failure.

1DESCRIPTION AND OPERATION
1.1 Purpose of use
The UDKG-01A “Gamma Sapiens” intellectual
gamma radiation detector (hereinafter called the
detector) is designed to measure ambient dose
equivalent (DE) and ambient dose equivalent rate
(DER) of gamma radiation and transfer measured
data to asmartphone or a tablet via the Bluetooth
radio interface.
The detector is used to:
-monitor personal radiation safety;
- monitor apartments, buildings, and
constructions, household items, clothes, soil
surface of grounds, and vehicles exposed to
radiation.
The detector is not applicable for use in nuclear
power facilities.
