Press F1 or F3 key to move the highlight cursor;
Press arrow keys to increase/decrease the
values.
Press
or F3 key to confirm the setting.
Press
key to cancel the change and close
current dialog box.
Note:
The setting limit cannot exceeds the measure range.
If the lower limit is larger than the upper limit the instrument will prompt an error message.
4.2 Memory manager
Memory Manager is used to manage (view, delete) the internal data storage. On the memory manager
dialog box, it shows each stored file name, mean value of the each test series, and test time of each
series.
Press arrow keys to navigate to the desired line
Press F1 key to delete all test series.
Press F2 key to delete the high-lightened test
series.
Press F3 or
key to view the content of the
high-lightened test series.
Press
key to close the dialog box.
On the view data dialog box (see right), it shows
the series file name, the test time, material, impact
device, impact direction, average test value and
all individual test value.
Press arrow keys to navigate up and down.
Press F3,
or
key to close the dialog box.
4.3 Base calibration (Impact device calibration)
Base calibration is based on a standard conversion function
std
H
(L) and shifts this vertically so that the
conversion of the specified HL value L1 coincides with the known converted value H1.
Base calibration is typically used if only one workpiece with known hardness in the required scale is
available or all available reference pieces have hardness values that are grouped closely together. The
workpieces to be measured are made from the same materials and their hardness differs only slightly
from the reference hardness.
Procedure of the base calibration
：
Open the base calibration dialog box.
Check if the type of the impact device is correct.
Perform five vertical down measurements on a
reference block.
Use F2 and arrow keys to increase/decrease
the nominal value.
To save the new calibration results, press the
F3 key. Or press F1 key to cancel the
calibration and exit.
The new calibration results are saved to the main unit and will be used automatically in the following test.
Note:
Base calibration for a impact device must be carried out before enabling auto detecting the
