How can we know more about electronic scales?

Electronic fat scale, hereinafter referrΩ'←ed to as electronic scale, h"πas been increasingly welcomed by oper∏♣♠ators and vast customers in theγα↑≈ field of circulation, and its utilizatio↕↔‍®n rate is increasing year by year. However, ∞​♥δcompared with traditional lev↔↕erage principles (such as AGT, TGT) and double-s×✘λ®ided tension spring dial scale®₹∑s, electronic scales are qu±δ☆ite different in weigh​Ω✘ ing principles, and the weighing characteri≠ ≤stics of electronic scales are not wα‍↔ell understood by the users.σ♠ γ

The operation principle and characteristiו∑c digital signal of the electronic scale are pr∞×®ocessed by the left line of the sin↕∑gle chip computer. Aλδ&♠fter keyboard input, the display←π★ part is visualized, and then t✘♣he whole process of unit price, measurement aπ↔€nd weighing is comple₽β↑ted. In fact, the weighing results are actuall☆λ₩<y known as the gravity of objects anβ↓d closely related to the g value o'♠‌$f gravity acceleration. ↑‍The operation principle ↑←←≈of electronic scale is obviously differen¥≥£t from that of lever scale in t™®hat the sensor of electronic scale makes elastomeδ λr produce an electric signal U£ ≠ after being attacked by the gravity of the mas✔₹&s Mo of the said object, and then converts anaε±÷log signal into analog€  signal by A/D converter.

The verification principle of↔  electronic scale When the eφ♠lectronic scale performs the verification fuσ₹nction, the single chip computer will active☆λ÷₩ly change the electric ♣φ♦€signal value and get the same white IF →↑↓>display value. Therefore, in the future∑$, the data of the database will bα¶e changed. In the future, each weighing of elect'←"ronic scales will sha≈φre with the modified standard data to get the c↔→♠orrect data.

Attention and protection in the use≠•¥∑ of electronic scales

1. Because the accuracy of the ele‌εctronic scale is higher than that of theσ≠₹ machine weighing device and there are mo‌±re software to use, the following points £ε♠should be paid attention✔α to when using the elec±β♣>tronic scale:

(1) The electronic scale should be installed on a¥← stable platform and rotated fo✔‌‍₹ur supporting columns so that the ai£≥λ∏r bubbles of the level meter ≠☆∑are in the center and the scale is in the ± horizontal state. When adjusting, try n©$¥♣ot to adjust the supporting columns too ®₽αγhigh. After adjusting, screw the adjustiπβng screws with nuts.

(2) the outer zero line grounding,→×≤ that is, the plug of the₩™ electronic scale is neces™π​sary for the three wire plug. There are thr•αee effects: in case the ♦♠±φexternal electronic circuit is damaged, the ope®©rator's safety can be ensured; in case of÷↕  external electromagnetic field dis↔∏turbance, the progressive system can resist inter∏εnal ability; in case the powder is placed on thγ e load-bearing disc, the electrostatic §★energy produced by the particle frict€↓♠ion can be quickly rel™ε∞eased to prevent the impulse ∞ noise caused by it and make the siπ★‍>ngle-chip computer act  ≤∑incorrectly.

(3) No weighing under↕↑ ☆ direct sunlight, no weighing under conditions o​©f less than 10 and above​× 40 C, relative brightness greater than π₽☆90%, voltage change beyond (coincid₹β&ence + 10) clarity, frequency ch<®λ&ange greater than 2% of taxi,'☆&σ and no working under severe osc‌¥illation environment.

(4) Do not allow wate₽←r to wash or rain, otherwise it will damageφ₹∏ the electronic circuit, and there is a ri←>≈↕sk of fire and elect ≈★Ωric shock; do not allow strong δ$decaying contact media and strong solvents to to±φ®uch the load-bearing disk, otherwise it ∑±will damage the disk surface. ‌₩;

(5) avoid weighing gooγ ds when weighing.

2. electronic scale maintenance

(1) weighing goods should ±€be placed on the bearing plate to prevent im☆π± pact.

(2) excessive weighi‍σ‌ng (overload or overload) is not÷©↓ allowed.

(3) pay attention to the replacement o∑αf price indication unit pric₽β™e at any time according t ©o the status of the alleged object.

(4) when the electronic scale is not used, good&£s must not be placed on the bearing plate §•for a long time.

(5) it is necessary to ™σπunplug the power plug and clean the scales γ§with clean cloth and cover the protective cover₩₽.

(6) in the operation of€₩β keyboards, quietly tou♥÷ ching, strictly prohibit fingernail percussion$≤©.

(7) Electronic scales shall no× ÷'t use solvents such as &→♣☆×quot;in-class" to scrub their appearance ✘≥in order to prevent the surface dec★★₽oration layer from being seriously corroded and"¥™ scrapped.

(8) If an electronic scale is enclosed in an acc±÷↔↓ident, the user may not disassemble it by hi€♣ mself. The measuring instrum‌∑ents and duplicate repair department should <©¶ be invited to repair it in tΩ♣→ime in order to prevent s₽÷₹φerious damage to the electroni σ•≠c scale components.
