400, which changed from Leeb hardness value measured
by D type impact device.
Note: HL values which measured by various impact
devices are various. For example: 700HLD≠700HLC.
5 Special prompts
Replacing impact device must be performed under the
condition of turn off, otherwise the impact device type can
not be identified automatically, and even it is possible to
cause the damage of circuit board of the tester.
In normal conditions, the current measured value can be
printed or stored if the 【 Impact times】 value which had
been set is not satisfying. If the printing and storing are
required at this point, 【 Average】 key can be pressed to
finish measurement, then printing can be carried out.
The functions of 【 Auto Save】 , 【 Auto Print】 , and 【 Auto
Trans.】 will be inactive in case of pressing【 Average】 key
to finish measurement in advance.
Only D and DC type impact device have strength
measuring function so that 【 Hard/
σ
b
】 setting can not be
changed if other types of impact devices are used; if the
setting has been changed into 【σ
b
】 via D/DC type impact
devices, the 【 Hard/ σ
b
】 setting will be changed into
【 Hard】 when other impact devices had been installed
instead of D/DC type impact device.
When 【σ
b
】 has been set, hardness scale will not been
set (cursor will skip off 【 Hardness Scale】 ).
Not all materials can be changed into every hardness
scale, hardness scale will return to Leed hardness (HL)
automatically after material has been changed. So
【 Material】 will be set firstly when setting measurement
parameters, and 【 Hardness Scale】 should be set
subsequently.
6 Detail Testing procedures
6.1 Start-up
Press key to turn on the equipment, following interface
will be displayed.
Tester will check and display the type of impact device. At
this point carefully observe whether the type is right or not,
then enter the main measuring display interface.
6.2 Turn On or turn off
Tester can be turn on or turn off by press key in any
display status.
6.3 Testing
The tester will enter the main display interface after turn
on, as the following figure
The measured values are displayed with big font in this
interface, and multiple shortcut key operation functions
supplied.
6.3.1 Explanation of the main display interface
Battery information: displaying rest capacity when no
charging, and displaying charging degree when charging.
Impact direction: current impact direction.
Average value indicator: average value will be displayed
when impact times setting has been achieved.
Hardness scale: the hardness scale of current measuring
value.
Measured value: current single measured value (without
average value indicator), current average value (with
average value indicator). It expresses the value is more
than conversion or measuring range when is displayed;
and it expresses the value is lower than conversion or
measuring range when is displayed.
Material: material that has been set currently.
Impact times: impact times that has been finished will be
displayed when measuring; Impact times that has been set
will be displayed when impact times is been set by shortcut
key, and the times which corresponding to single
measured value will be displayed when viewing single
measured value.
6.3.2 Testing procedures
Testing can be carried out under this interface status, and
the current measured value will be displayed whenever
one measurement is finished. The counting of impact times
will add 1 per measurement is performed. The buzzer will
send out a long sound provided that the value exceeds
tolerance limit; and the buzzer will send out two short
sounds if the impact times which has been set is achieved.
After 2 seconds waiting, average value will be displayed
with a short sound given out by buzzer.
6.3.3 Key operation
Press 【 SAVE】 key to save current group data. The key
can only be active after average value has been displayed;
furthermore the save can be done only once.
Press 【 DELETE】 key, the latest single measured value
can be deleted, but the deletion should be confirmed in the
following interface.
