How can we know more about elec γ£tronic scales?

Electronic fat scale, he$€‍reinafter referred to as electr ¶₽₹onic scale, has been♦® increasingly welcomed by operat←↓ors and vast customers in the field γ©±®of circulation, and "↕its utilization rate is increasin₩¥g year by year. However↔₩§₩, compared with traditional levera←®ge principles (such as AGT, T £↕GT) and double-sided tension‌↑'≥ spring dial scales, ele‌✘ ctronic scales are quiteφ≤ different in weighing princi♥↔✔ples, and the weighi   ng characteristics of electronic scale'→→πs are not well understood by the user∑↓α₹s.

The operation principle an♥≈£≤d characteristic digital signal of the₽​ electronic scale are®↓∑ processed by the left line o♣λ®₽f the single chip compu™Ω↕©ter. After keyboard input,ε•π the display part is ↓Ω★≈visualized, and then ​"≈÷the whole process of unit price, measur≈§$•ement and weighing is completed. In f☆​♥¶act, the weighing re↓↕₽∏sults are actually known as the'‍≥ gravity of objects anβ←d closely related to th©φ£↔e g value of gravity accel✔•eration. The operation principle of ele₹✘ctronic scale is obviously diφ<≠φfferent from that of ₹‍↕÷lever scale in that the sensor of elα×₩ectronic scale makes e∏↕πlastomer produce an electric signal →≈↔U after being attacked by the grav≈÷≥ ity of the mass Mo of the said obje₩α©ct, and then converts analog s≥¥≈πignal into analog signaσ♣±±l by A/D converter.

The verification principle of electrπ ↕onic scale When the e₽♦•lectronic scale performs th✘σe verification function©π, the single chip computer‌←α> will actively change the <​electric signal value and get the α​€αsame white IF display value. The₩∞refore, in the future, the data of th‌↕≥e database will be changed. In th​→e future, each weighing of electronic s→βcales will share with ↕≠the modified standard daε✔₩<ta to get the correct $÷'γdata.

Attention and protectioΩ∞n in the use of electronic scales

1. Because the accuracy of the electron→"&ic scale is higher than that of the m↔>achine weighing device an♣∑d there are more softw ±¥are to use, the following points≠€§& should be paid attentio®≤n to when using the electron♠ε• ic scale:

(1) The electronic scale§β★λ should be installed on a stable p✘∏¥★latform and rotated four supporting co♣δlumns so that the air bubbles of t✔₽he level meter are in the center→σ and the scale is in the horizontal∑  € state. When adjusting, tr€♣₩¥y not to adjust the suppoβ✘εrting columns too high. Af₽✘ter adjusting, screw the a±÷djusting screws with ∞$nuts.

(2) the outer zero line ground €☆¶ing, that is, the plug oε∑ f the electronic scale is neces♦α←sary for the three wire plug.≈♥ There are three effects: in case<  the external electronic circuit is da∏§εmaged, the operator'λ×;s safety can be ensured; in cש♣ase of external electromagnetic f↔‍∑ield disturbance, the progressive ‌βsystem can resist inter✔∏™"nal ability; in case the p ☆owder is placed on th×∑©e load-bearing disc, the electrost÷÷§atic energy produced ​≤≤by the particle friction ca$£β$n be quickly releaseε±₽d to prevent the impulse noise caused ♣β®by it and make the single-≤>chip computer act incorrectly.

(3) No weighing under dir∑∑♥ ect sunlight, no weighing under co↑∏nditions of less than 10 and 'γ™above 40 C, relative≤←>γ brightness greater than 90%, vol↕πtage change beyond (δ<γcoincidence + 10) clarity, f÷♣§♣requency change greater than 2% ofδ'$≠ taxi, and no working ♠∞≈ under severe oscillation enviro∞↓nment.

(4) Do not allow wat∑φ✘δer to wash or rain, otherwise it will ♣™★•damage the electronic circuit, and®∏•‌ there is a risk of ≥β ∑fire and electric shock; ​≥‍§do not allow strong decaying contact meδφdia and strong solvents to to∏®uch the load-bearing disk, otherwiseσ€ it will damage the disk su ↔ rface. 

(5) avoid weighing goods wh±ε∞en weighing.

2. electronic scale mainten←&ance

(1) weighing goods shou₩÷πld be placed on the bea₽★₽&ring plate to preven÷♥t impact.

(2) excessive weighing (✔¥→overload or overload) is not a¶↓βllowed.

(3) pay attention to the replace÷ ≤∑ment of price indication unit p≥±✔∞rice at any time accord​$ ing to the status of the al£$∑leged object.

(4) when the electronicβ↔★→ scale is not used, goods must not beπ' placed on the bearing plate for a long≥× time.

(5) it is necessary to unplug≠ε± the power plug and clean the σ↔scales with clean cloth and cover th £εe protective cover.

(6) in the operation of key'★‍‍boards, quietly touching, strictly ↔"↑ prohibit fingernail p ±βercussion.

(7) Electronic scale¶✘≥™s shall not use solvents such©"σ∞ as "in-class" to÷εβ scrub their appearanc↑¶e in order to prevent the surface deco∞παπration layer from being se¥×riously corroded and scrappe££✘d.

(8) If an electronic scale is♠× enclosed in an accident, thγ'e user may not disasse™β‍δmble it by himself. Th©α"e measuring instruments'φ€ and duplicate repair δ←₩department should be invited to repair¶∑ it in time in order to prevent seriouε"s damage to the electroδ♥÷αnic scale components←♥∏¥.
