Quick Start

HT360 series user manual



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.



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.

Adjusting the support

When using the instrument, the user can open the standing foot as a support to tilt the

instrument upward for easy operation and observation. When the instrument is not in

use, the user can close the support to facilitate placing or moving.
