6.15  Connection of Data Transmission Cable 

 

One connection plug of transmission cable  (optional parts) 

has to be inserted into the socket on the upleft side of the 

main body . The other plug has to be inserted into the USB 

socket in the back of the computer.

8.      Servicing & Maintenance 

 

8.1    Impact Device Servicing 

 

After  1000  to  2000  times  of  usage,  the  impact 
body and the guide tube have to be cleaned with 

the  provided  nylon  brush.  When  cleaning  the 

guide  tube,  the  support  ring  has  to  be 

unscrewed first. Then the impact body has to be 

taken out. The nylon brush has to be spiralled in 

counter-clock  direction  into  the  bottom  of  the 

guide  tube.  It  has  to  be  taken  out  and  repeated 

for  5  times.  At  last,  the  impact  body  and  the 

support ring have to be installed again. 

 

The impact body has to be released after use.

 

 

Any  lubricant  is  absolutely  prohibited  inside  the 
impact device.

 

 

8.2    Normal Maintenance Program 

 

*  If  the  standard  Rockwell  hardness  block  is  used  to  test 

and if all the error is bigger than 2 HRC, the ball top of the 

impact  device  or  the  impact  object  may  have  to  be 

changed. The invalidation may be caused by abrasion. 

*  If  any  other  abnormal  phenomena  appear  to  the 

hardness  tester,  nothing  may  be  dismantled  or  any  fixed 

parts may not be adjusted by the user himself.  

The  warranty  card  has  to  be  filled  in  and  sent  to 

ARROWELD  GmbH.  The  warranty  service  will  be 

performed within a few working days. 

 

9.      Calibration 

 

The 

HMR 

hardness tester has to be calibrated 

every year

.   

 

10.    Transport and Storage Conditions 

 

 *  The  instrument  has  to  be  kept  away  from  vibration, 

strong  magnetic  field,  corrosive  medium,  dampness  and 

dust. Storage in ordinary temperature. 

 

 

 

 

 

DESIGNED IN REGARD TO THESE STANDARDS:
