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 condition, the current measured value can be printed or
stored if the
【
Impact times
】
value which had been set is not satisfy. If
the printing and storing are required at this point,
【
Average
】
key can
be press down 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 down
【
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 type impact
devices are used; if the setting has been changed into
【σ
b
】
via D/DC
type impact device, 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.
