5.3 Hardness/Strength testing
Press
key to switch between hardness testing and strength testing (бb) .
Note: Only D and DC type of impact device has the function of strength testing. So hardness
testing is the only selection if the impact device is not D or DC type.
In hardness testing, Press
key to change the hardness scale. The supported hardness scale includes:
HL, HV, HB, HRC, HS, HRB and HRA.
Note
：
Here only displays the valid hardness scale for the present selected impact device and
material. It would not display the hardness scale which is not valid.
Please select material firstly, then select hardness scale.
Presetting hardness scale recovers to HL automatically after presetting material is changed.
5.4 Impact Direction Setting
Press the
key to move to the impact direction that you will preset.
5.5 Average Times Setting
You could modify average times within the range of 1 to 32 as following:
1) Press
key in testing state. The impact times item will begin to flash;
2) Press
or
key to set the average times to the number you want.
3) Press
key finally to exit from the operation.
5.6 Data logging
At most one hundred files (F00-F99, one group as one file) can be stored inside the gauge. By
simply pressing the
key after a new measurement finishes-the screen showing the “AVE” icon, the
measured hardness/strength group values will be saved to memory. The new saved file is appended as
the last file of the memory. This function provides the user with the ability to view/delete a file/group
previously saved in memory.
5.6.1 Viewing stored file/Group
To view the memory data, follow the steps:
1) Press the
key to activate the data logging function. The memory icon will appear. It will display
the current file name, the test parameter of the group data and the mean value of the group. If there
is no data in the memory, it will display: <E04>, which means no memory data, and then return back.
2) Use the
key and the
key to select the desired file to view.
3) Press the
key to see details of that group data.
4) Use the
key and the
key to view each single measured data in that group while viewing
details.
5) Press the
key to return to previous screen at any time during data logging.
5.6.2 Deleting selected file/Group
The user may require deleting a file from the instrument memory. The procedure is outlined in the
following steps.
1) Press the
key to activate the data logging function. The memory icon will appear. It will display
the current file name, the test parameter of the group data and the mean value of the group. If there
is no data in the memory, it will display: <E04>, which means no memory data, and then return back.
2) Use the
key and the
key to scroll to the file that will be deleted.
