Measurement

Tur n on the mach ine. Pres s setup button and set statisti c times, select the mat erial code accordi ng to the back label, then pre ss retur n button back t o measureme nt mode.

Note: The value can only convert to “Mpa” When select the material code 11~20.

Pres s up arrow bu tt on to selec t right conve rsion sca le. Note

1. The conversion value is “---” indicated the conversion is out of range.

2. Conversion value only supplies the general reference, which may result in some offset. Precisely conversion generally needs related comparative tests.

Samp le Prepar ation: Inap propria te sample will cau se a grea t m easuremen t erro r.

Ther efore, users should make the necessar y hand ling and prep aration u nder the orig inal cond itions of sam ple. Prep aration of the sa mple and th e s urface of tes t s hould be coin cident wi th the follow ing basic r equiremen ts:

1) Dur ing the pro cess of sam ple surfa ce pre paratio n, u sers shou ld avo id the imp acts of cold p ro cessing and the rmal proc essing.

2) The sample surface is plane for bett er, the test sur face shou ld be with a m etallic sh een, and not invol ve oxide laye r orot her stains.

3) Rou ghness of the t est surfa ce Ra ≤ 1.6

4) Sample must be of su ffic ient quality and rigidi ty. If i t's la ck of q uality an d rigidit y, it may caus e displac ement or shaking i n the pr ocess of test ing impac t, which can le ad to large e rrors. Gene rally spe aking, if the s ample qua lity is more th an 5kg can be di rectly tes ted; if the sample qua lity is 2~5 kgs, the sample shou ld b e taken in fixa tion test b y means of appr opriate clam ping; if t he s ample quality i s 0. 1~2kgs, the sam ple shou ld be c onducted coup ling bef ore th e te st; if the sampl e qu a l i t y i s l e s s t h an 0. 1 k g , t h i s h a r dn e s s t e s t e r is inap propria te to use. Coup ling meth od: Testing sam ple's back should be p repared to make a pl ane as a sup porting surf ace wit h a s mo oth form ation. Fi lling with a li ttle coup ling substa nce (Indu stry Vaselin e can b e used), users can no w pres s to th e surf ace of the sup porting obje ct (The weigh t of sup porting ob ject should be mor e th an 5 kg, and it ca n be rep laced by test block) to stic k into integr ation.

5) S amples sh ould be t hick enou gh and wi th sufficie nt surfac e abso rption layered. If users use D-t ype im pact device, the thic kness of sa mple should n ot be less th an 5mm, and sur face abso rption layer (or surfac e-hardeni ng laye r) s hould not b e less t han 0.8mm. To accurat ely measure t he h ardness o f th e mate rial, the best way is to remove the surfa ce-harden ing mate rial, the best way is to remove the surfa ce-harden ing laye r by proces si ng.

6) When test ing s ample surf ace i s not ho rizonta l, th e curv ature radiu s of testin g and nearby su rface sho uld be

larg er t han 30mm. And approp riate suppo rting ring shou ld b e elec ted and ins talled.

7) A s ample should not be with magnet ic. The signal of the

impa ct device wou ld be serio usly inter fered in the w or k by the magn etic, whi ch m ay cause in accurate te st result s.

Meas uring Ste ps:

Load ing: S imply load the impact devic e by sliding the loadi ng tube f orward.

Plac e: Then pla ce and hold the impact device on th e surface of the test piece at the desir ed test p oint. Impact ind irectio n

shou ld be verti ca l with the te st of surface .

Burs t imp act (Measure ): Trigger the impact by pres sing the rele ase butt on. The har dness va lue will be insta ntaneousl y disp layed.

Read o ff t he test resul t from screen .

Note : Gene rally, ea ch measu rement l ocation of sam ple is cond ucted f or th e five tests . The “ S” (diffe rence o f maxim um valu e and minimum va lue) value s must be less than 15 HL. The d istance between any two impa ct posit ion shou ld be ≥3 mm ; the d istance b etween impa ct positi on and the ed ge of the samp le should b e ≥3 mm.

Memo ry: The data group (suc h as test resul t, conversio n res ult, sample mate rial an d impac t directi on) aut omatica lly save in memo ry afte r one i ndividu al measure ment. IS H-PHB ha rdness tes ter can s tore 99 sets of data, when measuring times more th an 99, the las t grou p of data will store the 99th po sition an d the fir st grou p of data wil l be erase d. The second grou p of data will be moved into the 2th position, simult aneously the position of oth er group of data , will be mov ed into lower p osition . Pres s down arro w button to enter me mory stor e mode, u se up and down b uttons to bro wsing the m emory.

Prin t (the printe r is option al): Afte r on e set meas urement press set up butto n an d let the p rint symb ol blink, n ow press retu rn button to pr int curre nt result.

Maintenance

Impa ct Device Mai ntenanc e: Afte r using 10 00-2000 ti mes, us ers s hould c lean the cat heter of

impa ct dev ice and impact body wit h ny lon brush, and scre w off the sup porting ri ng before clean the cath eter, and th en ta ke out the imp act body, rotate the nylon br ush in to the tube in an anticloc kwise dir ection, and p ull out whe n touchin g the bot tom. S o repe atedly, and then load up the impact b ody and supporti ng ring ; User s sho uld rel ease the i mpact body a fter use. And the lubri cant is ban ned.

Factors Affection Accuracy

Measuring And Conversion Range

Inco rrect opera tion o r improper te sting condi tions would hav e seri ous impact on testing accur acy. Follow ing is several common fact ors effect the ac curacy of tes ting for th e use of refere nce:

1) Rou ghness of sam ple surfa ce When the impact body impact on th e samp le, a small pit would arise on the sample surfa ce, s o a t the same time , sho uld f inish the surface of the sample. The more r oughnes s, the less cons umption of impact ener gy wherea s the less roug hness, the mo re consum ption of impa ct

ener gy. Acc ordingl y, the rough ness of s ample testing points o n the surf ace Ra≤ 1.6.

2) The sha pe of sample su rface Leeb testi ng princ iple deman ds the velocit y of rebound and impac t are on t he same lin e, because th e impact bo dy is moving in a metal tube . Even if the ve locity o f rebound and imp act are n ot on the same line , it also can s how h ardness fo r sur e, but the impa ct bo dy wo uld coll ide wi th t ube wa ll w hen it rebou nds, which will affect t he v elocity of rebou nd. Ther efore, a g reater error is on t est ac curacy. W hen the radi us of curvatu re of the t esting sampl e sur face is smaller, th e solu tion is the use of suitable var iant suppo rting ci rcle. If users requ ire special sup porting circ le, we can contribut e to design and proc ess.

3) The wei ght of the samp le If the sa mple weight must be larg er than or equal to 5kg, and not easi ly sway. If the samp le weight w ere less, the s ample wou ld need prop er tr eatment (I t is neces sary to in crease the supp orting or moun ting th rough coupling comp ress on larger weig ht test ing sta nd), and the test ing result s can be ac hieved in accur acy. There shou ld be a certain area at the testi ng po ints (the area require d to meet a set of test ing points) and no vi bration or shak ing. I f th e we ight i s not enou gh, users mus t be as much as possib le reduce the ji tter and slos hing by the method s of i ncreasi ng s upporting , couplin g and comp ressing . And supporti ng device s hould avoid s hock.

4) The sam ple stabili ty Any effective test s need to mi nimize possibl e inter ference from outs ide; it's more impor tant to dynamic me asure such as Leeb hard ness test. T herefore, meas uring only allowe d in stabl e har dness test ing system. If it's lik ely to l ead to s ample movem ent in t he t ests, user s should fi x it b efore tes ting.
