6.3.1 Full description of the Main Display 
 

Battery  information:

  displays  the  rest  capacity  of  the 

battery. 

 

Impact direction:

 

displays the present impact direction. 

 

Average  value  indicator:

 

it  appears  to  show  the  mean 

value when the preset impact times are reached. 

 

Hardness  scale:

 

Hardness  method  of  the  present 

measured value. 

 

Measured  value:

 

displays  the  present  single  time 

measured value (without mean value indicator), or displays 
the  present  mean  value  (with  average  value  indicator 
prompting). 

↑ 

means  that  the  value  is  over  conversion  or 

measurement  range. 

↓  means  that  it  is  lower  than 

conversion or measurement range. 
 

Material:

 

The present preset material. 

 

Impact times count:

 

Times that have been impacted. 

 

6.3.2 Testing Operation at the Main Display 
 

Testing operation can be carried out under this interface. 
After  each  impact  operation,  the  current  measured  value 
can be displayed. Impact times count plus one, the buzzer 
will alert a long howl if the measured value is not within the 
tolerance  limit.  As  soon  as  the  preset  impact  times  are 

reached,  the  buzzer  will  alert  a  long  howl.  After  two 
seconds,  the  buzzer  will  alert  a  short  howl  and  the  mean 
value will be displayed.  
 

6.3.3 Key Operation at the Main Display 
 

- The 

SAVE 

key has to be pressed to store the present 

group of measured values into memory. This operation is 
only valid after displaying the mean value. 
-  The 

DEL

key  has  to  be  pressed  to  delete  the  latest 

single  measured  value.  After  pressing  this  key,  on  the 

screen will be shown following:

   

The 

key  or  the 

key  has  to  be  pressed  to 

move the cursor to

has to be pressed to confirm. 

ESC  

has to be pressed to cancel deletion. 

-  The 

or 

key  has  to  be  pressed  to  display  the 

single measured value. 
- By pressing 

AVG  , testing can be ended although the 

preset impact times have not been reached and to display 
the average value. 
- The background light of LCD has to be switched on and 

off by pressing 

MENU  

has to be pressed to enter the system Preset 

Menu.  

- By pressing 

, the impact direction can be preset. 

TIME 

key  has  to  be  pressed  to  change  the  impact 

times  in  one  group.  The  impact  times  count  item  will  be 
highlighted when the 

TIME  

key has been pressed. The 

impact  times  count  value  will  be  added  one  with  each 
pressing.  The  value  will  roll  back  to  1  after  32  has  been 
reached. 
- The 

HD

key has to be pressed to change the hardness 

scale. 
- By pressing 

MTL 

material setting can be changed. 

Presetting  the  hardness  scale,  HL  is  automatically 
recovered after material presetting has been changed. 
 

6.4    Menu Structure 
 

Both,  presetting  system  parameters  and  additional 
functions, can be realised by menu operation. At the main
