Chapter I. Overview
This is a portable industrial non-destructive flaw detector, which can rapidly, easily and accurately inspect,
locate, evaluate and diagnose various defects (crack, inclusion and pinhole, etc.) in a workpiece without destruction.
It can be used both in a lab and field. The instrument can be widely used in any fields that need defect inspection and
quality controlling e.g. manufacturing industry, iron & steel metallurgical industry, metalworking, chemical industry,
etc., also be broadly used in the active safety inspection and service-life evaluation in such fields as aerospace,
railway transportation and boiler pressure vessels, etc. It is an essential instrument for non-destructive inspection
industry.
When the ultrasonic wave propagates in a job, one can detect the defect in it by the influence on the propagation
of ultrasonic wave based on the acoustic characteristic demonstrated by the defect in the material. Based on this
principle, by using ultrasonic wave one can measure such defects as crack, pinhole and inclusion in such media as
metal, non metal and composite, etc.

3.1 Overview of the Instrument
3.1.1 Designation of the Instrument’s Components
Fig.3.1 Outside Drawing of the Instrument
3.1.2 Functional Keyboard
Keys of BSM360 are included in three groups: Function group, usual key group and special function group.
There are 6 keys in Functional group, in which F1, F2, F3, F4, F5 are corresponding with the 5 functional groups on
screen, and the key <> is used for switching of pages; Usual key group comprises 9 key: Up,down, dB+, dB-,+,－,
gain step key, freeze key, Enter key. they are used for usual operating; and special function group consists of 9
keys: on/off key, full screen key, detection zone,gate A,gate B,Auto gain, extend keypeak
memory and measure display. Overall arrangement of the whole face is as following picture.Overall

arrangement of the whole face is as following picture.：
Fig.3.2 Functional Keyboard
Particular Operation Instructions of keys refer to appendix II.
3.1.3 Using of Power Supply
BSM360 can work with plug-in power supply (AC, DC adaptor) or battery.
The detector will switch the power supply to adapter automatically when the power supply adapter is used.
The detector will switch the power supply to battery automatically when the power supply adapter is turned off.
The batteries will be charged automatically When BSM360, which is equipped with battery , is power supplied with
adapter.
3.1.4 Working with Battery
Indicator for charging
At lower right corner of BSM360 horizontal scale, there are symbols for battery voltage:
Battery voltage high Battery voltage drops Battery voltage low
Fig.3.3 Battery status display
If it shows the symbol for low voltage, you must stop detection immediately and use adpter or charge it.

Ultrasonic Flaw Detector BSM360 86+010—51658378

Charging the Li Battery.
You can charge the Li battery by using an external battery charger. It is recommended to charge by using the
power adaptor in the standard kit of BSM360. Before using the charger, please read carefully the Operation
Instructions for it. The continuous charging time for Li (4.8Ah) battery is about 4h～5h.During the charging, Rapid
Charging indicator lamp (green) will light up; when the charging completes, the Rapid Charging indicator lamp goes
out.。
3.1.5 Connecting the Probe
Proper probe shall be connected when using BSM360 to inspect. So long that you have a proper cable, and the
working frequency is within proper range, any probe made by our company is suitable for BSM360.The probe
connector for BSM360 is BNC.
The probe shall be connected to the socket at top of the instrument casing. Both connector sockets , have
different function, sending socket at left (with red mark) and receiving socket at right (with blue mark) .With
Single-Probe mode, the sending socket can be used only. When connecting a double-wafer (TR) probe (one wafer for
sending, another for receiving) or two probes (one for sending, another for receiving), take care that the sending
probe shall be connected to the sending socket and receiving probe to the receiving socket .Otherwise, it may result in
loss or disorder echo waveform.
3.2 Operation
3.2.1 Basic steps
a) Get ready the job;
b) Insert the probe plug into the probe socket of the host, rotate tightly the locking nut;
c) press, turn on the instrument;
d) It will carry out self test;
In normal case, when you turn on the unit, it will automatically enter into the status that it is in during last
turning off. The instrument parameters are consistent with last turning off, but the waveform during last turning
off will not display.
e) Check voltage of the battery; If the power monitor shows that the voltage is low, it will turn off
automatically 1 min after alarming bell.
f) According to your application ,Ten independence setups can be applied, any criterion can be input freely,
we can work in the scene without test block.
Whether it needs to calibrate the instrument, if yes, ask a professional technician to calibrate it (refer to
chapter IV);
g) Measure;

3.2.5 Basic Operation Way
You can select a functional group by <Fn> key; select certain function by <Menu> key and ; at this time, you
can modify parameters of this current menu by Coder And for some functional menus, they are shared by two
functions, when you have selected such a function, by pressing or the corresponding <Menu> key, it can be
shifted to another function.
3.2.5.1 Selection of Functions
There are 5 functional groups displayed below the A-scan zone, which can be selected by the corresponding
<Fn> key, and the selected one will be highlighted. The four corresponding function items will be displayed closely
next to the right of A-scan zone, which can be selected by press “↑” or “↓” key key.
3.2.5.2 Multipurpose Function Items
In some cases, a functional item has two functions. thus they can be shifted by pressing down the press “↑” or
“↓” key key again or striking key. The symbol “>” displayed behind the function name means that it is a
multipurpose function item.
