R76 - I Internationalis commendaticiis quia non - automatic Adpendens instrumenta Facit nulla punctum et nulla profecta a valde maximus proventus, et non solum occidere mensurae requisita, sed etiam technica requisita, quia stabilitatem in nulla parte cuiuscumque appendens instrumentum est basic spondet in mensuram perficientur. In his verbis sunt propinqua ad nullus punctum, explicare, analyze rursus.
(I) expressio errore: differentia inter indicavit valorem de scale et verum valorem correspondentes massa (placitum).
(II) maximam licita errore: nam a scale quod est in reference situ et posuit ut nulla cum non onus, in maximam positivum vel negative differentias inter se indicavit, et correspondentes verum sit commendat
(III) zeroing fabrica: A fabrica, qui occidere indicavit valorem ad nullus, cum non est onus in carrier. Nam electronic squamas, comprehendo: semi - automatic zeroing fabrica, automatic zeroing fabrica, initial zeroing fabrica, nulla tracking fabrica.
(IV) zeroing accurate: post scale est zeroed, effectus ex errore in appendens effectus est in ± 0.25e.
(V) nulla punctum errorem: post unloading, in nulla parte libra ostendit ad valorem errorem, maximum permissibilis error in range of ± 0.5e ad primam calibratium.
(VI) nulla tracking fabrica: A fabrica qui statim maintains in nulla significans valorem intra quaedam range. Nulla tracking fabrica est automatic nulla fabrica.
Nulla tracking fabrica potest habere quatuor civitates: Non, non currit, currit, de operating range.
Et nulla tracking fabrica quod liceat operari cum:
- In indicavit valorem est nulla, aut equivalent of a negativa retia pondus valorem cum crassa pondus est nulla;
- Et statera est in stabilization;
- Et correctio non est major 0.5 E / s.
I. Nulla tracking Fabrica Test
Sicut ingens maior pars electronic statera products in Sina ad praesens, ibi est a nulla tracking fabrica, sic opus temptare in nulla parte erroris, oportet ut nulla tracking potest esse in operationem. Deinde nulla tracking fabrica "non currere" solum est ad induendum quandam pondus onus prope nullus punctum, ut nulla tracking extra operating range.
(I) determinare ad correptionem rate of nullus tracking fabrica
Ob pertinet signa et calibration ratio in nulla tracking disciplinam rate non determinari in modum, invenitur quod illic es aliqui in hac speculatione, conscie adducere ad nullus citius, ut ostenderet quod qualis est in productum de singulos products est optimum. Quapropter auctorem in ipsa operis modum potest cito in agro ut reprehendo sicco nulla tracking rate de scale.
Turn in potestate, stabiliendum saltem 30min, posuit onus de 10e onus carrier, ut scale "nulla tracking" est de operating range. Leniter applicare ad 0,3e onus ad intervallis de 2s et observe ad valorem.
Post III continuos 0,3e onerat, in scale ostendit a significant augmentum unam divisionem, significans, significans, significans, significans, significans, significant, indicans quod non est vel non agunt fabrica.
Si autem scale non visibly mutare valorem post III onera 0,3e, quod unitas adhuc operating et tracking Corrections in 0,5e / s.
Deinde, leniter removere III 0,3e onerat et scale ut ostenderet a significant diminutionem unius division.
Quare III 0,3e onerat esse solebat?
0,3e onus minus quam correptio rate of 0.5e / s; Et in III 0,3e onerat sunt maius quam 0,5e / s et minus quam disciplinam rate of 1e / s (quod requiritur disciplinam rate est incremented ad 0.5e / s intervals).
(II) specifically posuit quanto onus ultra in nulla tracking range
R76, ad tempus test in quaestione requiritur onus 10e ad extra nulla tracking range. Quare non 5e onerat, cur non 2e onerat?
Etsi in internationalis suasiones et pertinet ordinationes sunt scilicet stipulata quod correctio rate of nulla tracking fabrica oportet esse "0,5e / s" sed multos appendens in this puncto rate de tracking fabrica. Etiam aliquam appendens instrumentum fabrica, set in maximum disciplinam rate (currently videre maximum correptionem rate of 6e / s).
II. Nulla accurate reprehendo
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
Ad determinandum accurate nulla occasum est ut calculus ad "disciplinam errorem prius disciplinam" perficitur in calibration processus. Cum reprehendo accurate de scale, in pre - disciplinam errorem potest adeptus per formulam: E = I + + 0.5e - Δl - l. Ut scire magis verius errorem ad specifica appendens parte scale, necesse est corrigere eam in nulla parte errore, i.e.: EC = e - E0OCEPS.
Post corrigendum errorem appendens punctum per errorem in nulla punctum, quod potest corrigere valorem, quod leviter excedit ad maximum licitum errorem ut qualified, aut corrigere ut videtur esse in qualified range ut videtur esse in qualified range quod videtur esse in qualified range ut videtur esse in qualified range ut videtur esse in qualified range quod simpliciter. Tamen, prout utrum correctione qualified vel simpliciter, ad usura nulla puncto errore correctis data est facere in test results propius ad veram accurate de scale.
IV. Nulla error determinatio
First of all, the calibration should determine the zero point error of the scale in this way: before removing all the load from the load carrier of the scale, it is necessary to put a load of 10e on the load carrier, then remove the load from the load carrier, and put 0.1e additional weights in order until the value is obviously increased by one division (I+e), and the accumulation of the additional weights is ∆L, then determine the zero point error according to the method of the flashing Point, E = 10e + 0.5 E = 10e + 0.5e - Δl - XE = 0.5E - δl≤ ± 0.5e. Si additional pondus accumulat ad 0.8e, deinde: E0 = 0.5e - 0.8e = - 0,3e<±0.5e.
