4.5 Preparation before use

Preparation of sample surface

When preparing the sample surface, the influence of heating and cold working on the sample surface hardness shall be avoided as far as possible. If the measured surface is too rough, measurement error will be caused. Therefore, the tested surface must show metallic luster and be flat, smooth and free of oil stain. Curved surface: The test surface is better to be flat. When the curvature radius R of the tested surface is less than 30mm (type D, DC, D+15, C, E, DL impact devices) and less than 50mm (type G impact devices), small support rings or profiled support rings should be used for testing.

Figure 4 Curved sample face

Support of sample

1. No support is required for heavy samples;

2. For medium-sized samples, they must be placed on a flat and firm plane. The samples should be placed stably without any shaking;

3. The sample shall have sufficient thickness, and the minimum thickness of the sample shall comply with Table 3;

4. For the samples with surface hardening layer, the depth of hardening layer shall comply with Table 3.

Coupling

1. For the light sample, it must be tightly coupled with the solid support, the two coupling surfaces must be flat and smooth, the amount of coupling agent must not be too much, and the test direction must be perpendicular to the coupling plane;

2. When the sample is a large area plate, long rod or bending piece, if the weight and thickness are too large, it may cause distortion and instability of the sample, leading to

12

Quick Start

EN

inaccurate test values, so it should be reinforced or supported at the back of the test point;

3. The magnetism of the sample should be less than 30 Gauss.

4.5.1 Measurement

Before measurement, random hardness block can be used to inspect the

instrument, and its display error and repeatability shall not be greater than those

specified in Table 4.1.

1. Booting

a. Insert the impact device plug into the impact device socket on the upper side of the instrument; b. Press the key. When the power is on, the instrument enters the measurement state.

2. Loading

Figure 4 Loading

Push the loading sleeve downward to lock the impact body; For DC-type impact

device, place the loading bar on the test surface, insert the DC-type impact device

into the loading bar until its stop position, and then the loading is completed.

Press the support ring of the impact device tightly on the surface of the sample, and the impact direction should be perpendicular to the test surface.

3. Measuring

 Press the release button on the upper part of the impact device to measure. At this

time, the sample, impact device and operator shall be stable, and the force direction shall pass through the axis of the impact device;

 Each measuring part of the sample is generally tested for five times. The data

dispersion shall not exceed ± 15HL of the average value;

 The distance between any two indentations or the distance from the center of any

indentation to the edge of the sample shall comply with Table 4.2

 For a specific material, in order to convert the Leeb hardness value to other

hardness values more accurately, a comparison test must be conducted to obtain the corresponding conversion relationship. The method is: use qualified Leeb hardness tester and corresponding hardness tester to test on the same sample respectively. For each hardness value, measure five Leeb hardness values evenly around more than three hardness indentations that need to be converted. Use the average Leeb hardness value and the average corresponding hardness value as the corresponding values, and make a hardness comparison curve. The comparison curve shall include at least three groups of corresponding data.

Table 4 Measurement

4. Read the measured value

 Take average value of several valid test points as one Leeb hardness test data.  Display the hardness value in front of the Leeb hardness symbol HL. The HL

values measured by different types of impact devices are different.

4.5.2 Adjusting the support

7 Troubleshooting

1. If the power key is pressed, the screen is still black without any display.

1) Plug in the charger. If the instrument is on, the battery is dead or damaged. Charge

or replace the battery.

2) After the above check, restart the instrument.

3) If you still cannot use this product normally, please contact Hantek.

2. The screen display is too dark to see clearly

1) Check whether the brightness value of the LCD screen is too small. Press the

System > Backlight, press the direction keys to select the backlight, and

press to change the brightness of the LCD screen to an appropriate state.

2) Check the backlight time setting. Press System > Backlight, press the direction

keys to select the backlight time, and press to change the screen backlight time.

3. The instrument does not display the measured value

The sensor cable is faulty. Replace the sensor cable.
