One.Precautions
1. It is advisable to use the single‐phase 3‐pin plug for the electric connection on the present
instrument. The grounding end must be according to the stipulatedrequirementforearth
protecting.
2. Itisnecessarytoreadcarefullytheusageinstructionmanualbeforetheoperationofthepresent
instrument in order to know the operational procedures and the precautionssoastoavoidthe
damagestotheinstrumentandthepersonalsafetycausedbytheincorrectoperation.
3. Duringtheinstallmentandthe preoperational test,the stickingpaper thatprotectsthe indenter
againsttheshockduringthetransportationshouldbetakenoffcarefullybecausetheover‐strength
indoingitwouldaffectthepositionalprecisionoftheindenter.
4. Itisprohibitedtodismountandalternatewithoutpermissionalltheelectriccomponentpartsand
the switches as well as their fixed positions. Those who do such unwarranted actions will be
responsiblefortheirconsequences.
5. During the loading process, press the “START” key immediately in case of emergency, and the
instrumentwillstoploadingautomaticallyandreturntoinitialposition.
6. Duringtheloading,dwellingandunloadingprocess,presstheemergencystopbuttonimmediately

7. Our company tries to improve the quality of the hardness testers and renew their structure
continuously. In case the contents in the usage instruction manual are a bit different with the

Two.BriefIntroduction
1. TheVickersHardnessTesterisanewandhigh‐techproductcombiningtheoptical,mechanicaland
electronic techniques, with a good aesthetic aspect, operational functions and reliability, and
henceitisanidealinstrumentforthetestingofVickershardness.
2. The instrument adopts closed‐loop loading control system, it makes the test accuracy improved
andtherepeatabilityandstabilityofthevaluebetter.
3. Withthesoftkeysonpanelboardforinputoperation,itcanpresetthetestingforcedwelltime,
adjustintensityoflightsourceandshowstheindentationlength,hardnessvalue,dwelltimeand
thetestnumber.Ithasthefunctionofautomaticshiftingbetweentheindenterandobjective.
4. Accordingtotheparticularrequirementsoftheclient,thetester can be equipped with CCD
indentation automatically measuring device. The instrument is suitable for the testing Vickers
hardness value of the micro and thin pieces, permeated and coated plane surface, the crisp
materialssuchastheagate,glassanditis,therefore,anidealhardnessmeasuringinstrumentfor
the scientific research institutes, the universities, the industrial production units and the
metrologicalinstitutes.
