R76 - 1 International Kurudziro yeNon - otomatiki Kuridza Zviridzwa Inoita zero zero ne zero kuisa nyaya yakakosha, uye kwete chete zvinodiwa zviyero, Iwo mazwi anotevera ane hukama zvakanyanya ne zero poindi, tinotsanangura, ongorora zvakare.

. Zero tracking mudziyo ndeye otomatiki zero mudziyo.
ZERO Tracking mudziyo unogona kuve nenyika ina: Kwete, kwete kumhanya, kumhanya, kunze kweiyo renji rekushandisa.
Iyo zero tracking mudziyo unobvumidzwa kushanda kuti:
- kukosha kwakaratidzwa kune zero, kana kuenzana kweiyo isina kunaka net uremu kukosha kana huremu hwakanyanya hwave zero;
- uye chiyero chiri mukupokana;
-Kururamisa hakuna kukura kupfuura 0.5 e / s.
1. Zero Tracking mudziyo bvunzo
Sezvo huwandu hwakawanda hwezvigadzirwa zvemagetsi zveChina muChina parizvino, pane zero yekutevera chishandiso, saka kudiwa kwekuyedza zero pfungwa yekukanganisa, iwe unofanirwa kuve nechokwadi chekuti zero kutevera hakugone kushanda. Zvadaro, iyo zero inoteedzera chishandiso "haina kumhanya" nzira chete ndeyekuisa uremu hwemutoro pedyo neZero point, kuitira kuti zero yekutsvaga inopfuura huwandu hwayo hwekushandisa.
(1) Sarudza iyo yekugadzirisa rate ye zero tracking mudziyo
Nekuda kwezviitiko zvakakodzera uye maitiro ekugadzirisa zero anoteedzera kururamisa haana kutsanangurwa nenzira, akawana kuti kune vamwe vanhu pauwandu hwekururamisa, kuitira kuti varatidze kuti mhando yechigadzirwa chega chezvigadzirwa zvakanaka. Nechikonzero ichi, munyori akapfupikisa mubasa chairo wenzira, iwe unogona kukurumidza mumunda kuti utarise iyo zero yekutevera chiyero chechiyero.
Vhura Simba, Simbisa kweinenge 30min, isa mutoro wegumi nemutakuri mutoro wekutakura, kuitira kuti chiyero cheZero "chiri kunze kwenzvimbo yekushanda. Nyoro shandisa iyo 0.3e mutoro panguva dzekupindirana kwezve 2s uye tarisa kukosha.
Mushure me3 inoteedzana 0.3E mitoro, chiyero chinoratidza kuwedzera kwakakura kweimwe chikamu, zvichiratidza kuti chishandiso hachisi kana chisingazoshanda.
Kana iyo chiyero ichi chisingaoneki shanduko kukosha mushure mematanhatu emitoro ye03
Zvadaro, bvisa zvinyoronyoro iyo ye3 0.3E mitoro uye chiyero chinofanira kuratidza kukosha kwehuwandu hwekuparadzanisa.
Nei matatu matatu 0.3E mitoro iri kushandiswa?
Iyo 0.3e mutoro uri pasi pane iyo yekugadzirisa huwandu hwe 0.5e / s; Uye iyo 3 0.3E mitoro yakakura kupfuura 0.5e / s uye isingasviki mari yekugadzirisa ye 1e / s (nekuti iyo inodiwa yekugadzirisa huwandu hwayo hwakawedzerwa ku0,5E / S
(2) zvakananga isa kuti yakawanda sei mutoro unopfuura zero zero yekutevera
R76, panguva yekuedzwa iri mubvunzo, inodiwa mutoro wegumi kuti aiswe kupfuura zero zero tracking renji. Wadii kusati 5e mitoro, wadii kuita 2e mitoro?
Kunyangwe mune dzidziso dzepasi rese uye mitemo yedu yakakodzera inotaura zvakajeka kuti huwandu hweZero hweZero hwekutevera hunofanirwa kunge huchiita " Kunyangwe vamwe vakayera vhigadziri vechils, vakagadzwa mune yakanyanya kururamisa chiyero (parizvino vanoona iyo yakanyanya kururamisa chiyero che 6e / s).
2. Zero yeruzivo rwekutarisa
If the weighing instrument does not have zero tracking function, or there is a special switch to close the zero tracking device, in the detection of “zero accuracy” and “zero error”, there is no need to put additional load (10e). The problem is that most of the weighing instruments in China are not equipped with a switch that can close the zero tracking device, and they all have the zero tracking function, so in order to get the zero error, we have to put an additional load (10e) to make it go beyond the zero tracking range when the scale is unloaded, so that we can get the accuracy of the zero setting “near zero” and the “zero error”. This results in a “near zero” zeroing accuracy. Sequentially place 0.1e additional weights until the value increases significantly by one division (I+e), and the total of the additional weights is ∆L, so that the zeroing error is: E0=10e+0.5e-∆L-10e=0.5e-∆L≤±0.25e. If the total of the additional weights is 0.4e, then: E0=0.5e-0.4e=0.1e<±0.25e. .
3. Meaning of determining zeroing accuracy
Chinangwa chekusarudza chokwadi che zero mamiriro e zero ndeyekuti kuverengerwa kwekuverenga kwe "kukanganisa kwekugadzirisa usati watongwa" kunopedzwa muCalibration maitiro. Paunenge uchiongorora chokwadi chekero, iyo pre - kukanganisa kwekugadzirisa kunogona kuwanikwa neFomula: E = Ini + 0.5E - L. Kuti uzive zvimwe zvakanyatsokanganisa kukanganiso pane imwe nzira inorema pachiyero, zvinodikanwa kuti uzviruramise neZero Point Kanganiso, I.E.EC = E. E0WMPE.
Mushure mekururamisa kukanganisa kwekuremerwa nekukanganisa kweZero poindi, zvinokwanisika kugadzirisa kukosha kwekukwana kwekubvumirana kukuru, kana kugadzirisa kukosha kwacho kunoita kunge mukati memukati memhando yekukodzera. Nekudaro, zvisinei nekuti kururamisa kwakakodzera kana kusina basa, chinangwa chekushandisa zero point Kanganiso yakagadziriswa data ndeyekuita kuti bvunzo dziswedere pedyo nekujeka kwechokwadi kwechiyero chechokwadi chechiyero chechokwadi chechiyero chechokwadi chekero.
4. Zero kukanganisa kutsunga
Chekutanga pane zvese, iyo Calibration inofanirwa kuona iyo zero pfungwa yekukanganisa nenzira iyi: Ndisati ndatakura mutoro wekutakura of the Flashing Point, e = 10e + = 10,5 e = 10e + 0.5e - 10e = 10e = 100E - δL≤± 0.5E. Kana iyo yekuwedzera uremu ichiwedzera kusvika 0.8E, ipapo: E0 = 0.5e - 0.8e = = 0.3E<±0.5e.
