1 Abstract
1.1 Introduction
The analyzes that can be performed on structures in order to obtain
information on the armatures, the presence of irons or carpentry, is
called the magnetometric or pacometric survey. The aim of this
survey is mainly to locate the presence of bars and / or reinforcement
brackets on structural elements. Once the localization has been
carried out and the same are highlighted on the element, it will be
possible to carry out non-destructive surveys on the concrete thus
avoiding to have results falsified by the presence of irons or even to
cut them in the case of performing cores. All the Non-Destructive
investigations that have the objective of the mechanical
characterization of the building materials can and must be performed
after a pacometric survey.
Through the pacometric survey, in addition to the identification and
location of the reinforcements, it is possible to measure the diameter
of the iron and the thickness of the cover. This measurement must
always be verified by making an opening (removal of the concrete
cover) near the localized iron for checking or calibrating the
instrument.

1. Care and Maintenance
1 . Operation Notice
Do not operate the button with too much force and stain it with oil and
mud so as not to affect the button board life.
2. Power Supply
This product built-in rechargeable lithium battery is left in standby model
for at least 20h if fully charged. Please pay attention to battery indicator
when using, if the battery is low, you should turn off the power as soon as
possible and charge timely, otherwise the sudden power failure may

Rebar Locator DR 30000 PK
DRC s.r.l. – [e-mail] Page 7
cause loss of test data or even damage to the product.
Do not use other batteries or power supply for charging, otherwise it may
cause the damage to the product, battery leakage, fire etc. If you have
any problems, please contact us.
Tips: The battery capacity will be insufficient after it is used for
some time, which the symbol will be displayed in the top right
corner of the screen. The more the gray part, the more battery, the
symbol shows that the product need charging as the little gray part
displayed.
. Battery Charging
This product built-in lithium battery uses Micro USB standard port. It is
recommended that the battery should be charged under the shutdown
state. Please connect the power outlet to AC220±10%V power socket, the
other end Micro USB port access to the bottom of the product, or
connected directly on a computer with the USB cable.
If the indicator light turns red when charging, it shows the battery is
being charged. When the red light turns green or off, it shows that
battery has completely charged. The charger or USB cable should be
pulled out in time so as not to overcharge the battery and affect the
battery life. During the charging, there will be the normal phenomenon
that battery and charger will produce a certain quantity of heat. It is
recommended to place the product in a ventilated place.
Tips: In order to ensure the battery completely being charged one

Rebar Locator DR 30000 PK
DRC s.r.l. – [e-mail] Page 8
time, please keep charging for hours or so, and do not charge the
battery in an environment exceeding 50℃. It is recommended that you
should use the manufacturer's standard charger and USB cable, or it may
cause damage to the product.
4. Lithium Battery
General life of rechargeable battery is for charging and discharging 500
times or so. If the battery does not work, no power and low power when
charging, or working time is short every time, it may have been damaged.
Please contact our after-sales service department to replace new battery.
It is forbidden to short-circuit the battery and place it near the heat
source. The battery capacity is 2000mAH (7.4Wh).
5. Preserve ＆ Clean
When the instrument is not used, please place it in a ventilated, cool and
dry (relative humidity less than 90%) place of room temperature. If you
do not use for a long time, please charge it before using, and regularly
turn on it, and charge it once a month at least as well because
rechargeable battery will discharge automatically resulting in power loss.
After using the instrument each time, it should be properly cleaned to
prevent water, oil, mud and dust from the connector for fear of affecting
the test performance.
Tips: Do not immerse the instrument and accessories in water or
scrub them with a damp cloth! Do not use any organic solvents or acid
and alkaline liquid! Please use a clean, dry cloth to scrub the instrument

Rebar Locator DR 30000 PK
DRC s.r.l. – [e-mail] Page 9
and clean the jack with a soft brush.
6. Fault and Handling Method
Instrument cannot boot: please check the battery power whether it is
sufficient or directly insert it into the charger, turn on the soft switch. If
the above method is invalid, connect the charger to charge the battery
for half an hour before switching on.
Instrument automatic shutdown: the product has the function of the
detecting power capacity. The product will automatically shut down
when the power is too low, charge the battery for some time, or directly
insert it into the charger before switching on.
Tips: we provide a year warranty and life-long maintenance services.
Please contact us if you need maintenance service. Repair it by yourself is
not suggested.

3.2.2 Rebar Position ＆ Thickness Measuring
Select the Start Measuring (press 【Side Upper Button】if you want to
select “second range” H) and move the instrument rightwards slowly and
evenly along the concrete surface until the alignment mark displayed as
square-shaped frame is changed from (hollow square) to
(cross-line in solid square) , indicator light in the front of screen
turns red accompanied by the beep prompt tone, which shows the
instrument is precisely aboove the rebar and the rebar has been detected
yet. The current thickness value is displayed in the upper right corner of
the screen, as shown in figure .4.

c. Measuring Location Interface(Second Range)
Fig. .4 Rebar Position ＆ Thickness Measurement (a, b,c)
As the instrument moves away from the rebar, the square-shaped frame
moves away from the centerline again and gradually moves towards the
edge of the screen. When the measuring signal completely disappears,
the square-shaped frame and the centerline overlap without displaying
cross-line in the square-shaped frame.
In the start measuring interface, the scope by default is 600mm each

Rebar Locator DR 30000 PK

page, and automatically increase or decrease in multiples of 600 each
time. In the process of scanning, the system will automatically page if the
display is beyond the scope, press the 【▼】＆ 【▲】to view the previous
screen data, the before and after data in every screen will change
accordingly, except the middle data. Besides, during the measurement,
data thickness interval is automatically increased by 100mm each time.
NOTE: the instrument has not any device to measure distance; the
thickness interval is only indicative.
In the measuring interface, please operate the following buttons to select
the functions:
【 】: Save the measuring data and restart the next measuring
【 】: Clear the measuring data and restart measuring.
【▲】, 【▼】: Page up and down to view the before and after data page.
【Side Upper Button】: Switch the large ＆ small range.
【Side Lower Button 】: The rebar diameter ＆ the corresponding
thickness measuring.
Tips: The measuring modes are divided into the large range and
small range (by default). If the thickness is less than 80mm, please use
the small range. If the thickness is more than 80mm, please use the large
range.
