I. Product Introduction
The HTX-02 detects hardness based on the Leeb hardness measurement principle and
can measure the hardness of a variety of metal materials. The tester adopts advanced
dual coil technology for good repeatability and measurement accuracy. The probe has a
built-in direction sensor, which automatically compensates for the measurement error in
different impact directions. The instrument has a variety of built-in hardness systems,
which can be converted between Leeb (HL), Vickers (HV), Brinell (HB), Shore (HS),
Rockwell (HRA), Rockwell (HRB), Rockwell (HRC).The instrument adopts an impact
device D suitable for assessing the hardness of common metal materials.

III. Features
1. The tester uses advanced dual coil technology to increase repeatability and measurement
accuracy.
2. A Built-in direction sensor automatically compensates for the measurement error of different
impact directions.
3. Integrated handheld design makes the instrument compact and portable.
4. Provides a variety of interchangeable hardness scales.
5. Users can calibrate the standard parts to eliminate the error.
6. Low power consumption means it can work continuously for more than 100 hours.
IV. Operation
1. Power on/off
Power on:
A short press of the button and the serial number of the tester is displayed on the
screen. The instrument will then enter the measurement interface.
Power off:
A long press of the button will shut down the tester or click the “Shutdown” option in
the menu.
2. Measurement
Loading:
Push down the loading sleeve of the probe to lock the impact body.
Positioning:
Press the probe firmly against the surface of the object to be measured and keep it still.
Measurement:
Press the release button on the top of the probe to measure the hardness of the object.
3. Setup and Calibration
Press and hold the button for 3 seconds when off or press the button briefly
when in the measurement state to enter the Main Menu. There are five sub-options,
press the briefly to select [Language, Hardness, Material, Unit, Calibration, Exit,
Shutdown]. A short press of the button will confirm the selection.

Language: Short press button to enter the language option and press button to
select the right language, then press button to confirm your selection.
Material: Short press the button to enter the material selection interface, short press the
button to select the corresponding material, then press the button to confirm the
option.
Hardness Unit:The hardness unit is only displayed in the measurement mode. Press the
button briefly to enter the unit selection interface, press the to select then press the
button to confirm.
Calibration: Short press the button to enter the calibration interface, the screen prompts
[Please measure the standard hardness block], then you can measure the standard
hardness block (single or multiple times). After measurement, the cursor moves to the actual
value area, then press the button to adjust the actual value to the standard value of the
hardness block.
4. History Records
In the measurement mode, press briefly to view the historical data in the browse interface.
The instrument stores 9 sets of data, with the oldest recorded value automatically deleting
when there are more than 9 sets of data. Record 1 is the earliest test data. Recorded data is
not lost when the instrument is turned off.
When pressing button to view the data, the data record number is increasing from the first
one to the last one; when pressing button to view the data, the data record number
decreases from the maximum to the minimum.
In the history view mode or measurement mode, press button briefly and the screen will
show a data deletion prompt, press button briefly to select [Yes] to delete all recorded
data.

V. Notes
1. The surface of the material must not be too rough. It needs to be flat, smooth, free of
oil and grease.
2. The minimum mass of the test object is 5Kg, and the minimum thickness is 25mm.
For objects whose weight and thickness do not meet the requirements, the test must
be coupled with solid bracing.
3. After use, the impact body should be loosened.
4. The use of various lubricants is strictly prohibited in the impact device.
5. When measuring, the distance between any two indentations should not be less than
3mm, and the distance between the centre of the indentation and the edge of the
object to be measured should not be less than 5mm.
