Carefully read the Operation Manual before you use the hardness tester and get to know thoroughly the
operation procedure and the usage precautions so as to avoid the damages to the hardness tester and the
safety accidents caused by the improper operation.
All the bands and the anti-shock tapes should be carefully removed before the hardness tester is installed
and calibrated.
The single-phase 3-pin socket should be used for the power source of the hardness tester and the ground
connecting cable should meet the safety requirements.
It is strictly prohibited to tamper with the installed position of all the electric component parts, switches,
and sockets of the hardness tester without permission, otherwise it will cause accident.
Our company tries to improve the quality of the hardness testers and renew their structure. In case the
contents in the Operation MANUAL are a bit different with the actual structure of the instrument, it is hoped
and apologized for the fact that the further notice will not be given.
